Accurate patient education may improve treatment adherence and outcomes. Objective: To compare the accuracy, readability, and user experience of ChatGPT 4.0, Gemini 1.5 Flash, and Deepseek R1 in answering common patient questions about AGA. Methods: In February 2025, a cross-sectional study was conducted using 12 frequently asked patient questions on AGA, sourced from online platforms. The questions were submitted to ChatGPT 4.0, Gemini 1.5 Flash, and Deepseek R1. Two dermatologists independently assessed responses using a validated 4-point accuracy scale. Readability was measured with the Flesch-Kincaid Grade Level and Flesch Reading Ease Score. User experience was evaluated based on response speed, presence of visual aids, citation usage, and overall satisfaction. Inter-rater reliability was analyzed via Cohen’s kappa, and statistical comparisons were made between models. Results: ChatGPT 4.0 and Gemini 1.5 Flash successfully answered all 12 questions, with most re- sponses rated as “satisfactory with minimal corrections.” Deepseek R1 answered only five questions and frequently provided inaccurate content, especially when differentiating between AGA and cicatri- cial alopecia. It also lacked warnings about potential misinformation. Gemini 1.5 Flash included visual aids and citations, improving interpretability. All models generated responses at a high school reading level. In terms of user experience, ChatGPT 4.0 and Gemini 1.5 Flash outperformed Deepseek R1. Conclusions: ChatGPT 4.0 and Gemini 1.5 Flash provided accurate, readable, and user-friendly responses on AGA-related questions, making them promising tools for patient education under physi- cian guidance. Deepseek R1’s limitations highlight the need for cautious implementation. ABSTRACT 2 Original Article | Dermatol Pract Concept. 2025;15(4):5929 Introduction Hair is an important part of a person’s perception of beauty and individual image. Hair loss is therefore a significant problem, not only dermatologically but also psychologically [1]. The most common cause of hair loss in both males and females is androgenetic alopecia (AGA), or male pattern baldness. It is more common in the Caucasian race and has a slightly lower prevalence in individuals of Black and Asian ethnicity [2]. Androgenetic alopecia is a type of alopecia characterised by progressive miniaturisation of genetically predisposed hair follicles under the influence of androgens [3]. There are various topical and systemic treatment options available, but due to the progressive nature of the disease, these treatments must be continued over a long period of time. The lack of information about treatment duration and side effects leads to disappointment, which affects compli- ance and premature discontinuation. It is therefore import- ant that patients are provided with accurate and appropriate information [4]. Patients often use internet tools to learn about diseases and treatments, and artificial intelligence (AI) tools have recently been added. This situation has also led to publications evaluating the role of AI tools in patient ed- ucation [5]. ChatGPT 4.o, Google’s Gemini Flash 1.5, and DeepSeek R1 represent a new generation of large language models (LLM) that leverage advanced artificial intelligence tech- niques, specifically deep learning methodologies, to generate responses to natural language prompts that exhibit char- acteristics reminiscent of human interaction. These models are initially pre-trained on extensive textual data, followed by fine-tuning to facilitate conversational responses to a range of user commands [6-9]. Improved patient interaction can be achieved by integrating AI models into the field of dermatology. In consideration of the aforementioned factors, this study was designed to compare responses from ChatGPT 4.o, Gemini 1.5 Flash, and DeepSeek R1 to a series of patient inquiries concerning androgenic alopecia. Methods A search for “patients’ questions about androgenetic alope- cia” was conducted using Google (www.google.com). The Frequently Asked Questions sections from various clinics were analyzed. From a list of twenty questions, the 12 most frequently asked were selected by a dermatologist with ex- perience in hair-related conditions who evaluates approxi- mately 800-1000 patients annually. The selected questions were presented to ChatGPT (version 4.o, the latest free version as of 2 February 2025), Gemini 1.5 Flash, and DeepSeek R1 chatbot in a single session without follow-up or repetition. Two dermatologists independently reviewed all responses using an evidence-based framework. The second reviewer is a dermatologist currently working at a Training and Research Hospital, where he man- ages tertiary-level patients. He has clinical experience in the management of hair disorders and evaluates approximately 700–800 patients annually. Responses were evaluated using the Mika et al. rating system, previously utilized in AI-related medical research [10]. This system assigns scores on a four-point scale: 1. Excellent (no clarification required): Complete and aligned with the existing literature 2. Satisfactory (minimal clarification required): Lacking mi- nor details but generally accurate 3. Satisfactory (moderate clarification required): Contain- ing outdated or partially irrelevant information 4. Unsatisfactory (substantial clarification required): In- cluding erroneous or overly generalized information that could lead to misinterpretation To ensure consistency and reliability in scoring, each re- sponse was rated independently by two dermatologists, and inter-rater agreement was calculated. The readability of the responses was assessed using the Flesch-Kincaid Reading Ease Score (FRES) and Grade Level (FKGL), widely used tools for evaluating text readability [11]. The FRES provides a score between 0 and 100, with higher scores indicating easier readability. For instance, a score of 70–80 corresponds to a 7th-grade reading level, whereas a score of 30–50 corresponds to a college-level read- ing ability. The FKGL represents the minimum educational background required for comprehension. As this study solely analyzed publicly available online content without involving human subjects, ethical approval was not required. Statistical Analysis The data analysis was conducted using the IBM SPSS Sta- tistics version 25 software package (IBM Corporation, Armonk, NY, USA). The normality of the distribution of continuous variables was assessed using the Shapiro-Wilk test, and descriptive statistics are reported as mean ± stan- dard deviation for continuous variables. Categorical data are expressed as frequency (N) and percentage (%). The Flesch-Kincaid Grade Level (FKGL) and Flesch Reading Ease Score (FRES) for the responses provided by each large language model (LLM)-based AI application (i.e., Chat GPT, Gemini Flash 1.5, DeepSeek R1) were calculated using an on- line Flesch-Kincaid calculator tool available at the Good Cal- culators website (https://goodcalculators.com/flesch-kincaid -calculator/). The statistical significance of differences in Original Article | Dermatol Pract Concept. 2025;15(4):5929 3 FKGL and FRES levels across the applications was evalu- ated by repeated-measures analysis of variance via Wilks’ lambda test. As DeepSeek R1 failed to provide responses to four of the directed questions, the subsequent analysis fo- cused on the subset of fully answered questions. The differ- ences in FKGL and FRES levels between ChatGPT 4.o and Gemini were assessed by a paired samples t-test. Finally, the responses to each user experience question were visualized as bar graphs for ChatGPT, Gemini Flash 1.5, and DeepSeek R1, and descriptive statistics were calculated for the scores obtained from each subdomain. To assess the agreement be- tween the dermatology specialists’ evaluations, kappa coeffi- cients and their standard errors were calculated. A p-value of less than 0.05 was considered statistically significant. Results The questions and answers of ChatGPT 4.o, Gemini 1.5 Flash, and DeepSeek R1 are shown in Table 1. ChatGPT 4.o and Gemini Flash 1.5 were able to respond to all 12 questions in succession without interruption, while DeepSeek R1 was able to answer only five. When it came to the 6th question, DeepSeek R1 replied, “The server is busy. Please try again later.” The same question was asked again five minutes later, but the same response was received. After 10 minutes, the same question was asked again, and the same answer was received. Then, when the 7th question was asked again, “The server is busy. Please try again later,” and no response was received. DeepSeek R1 was able to respond to each subse- quent question after about 15–20 minutes, but the waiting time gradually increased. It was decided that, considering that waiting for more than 20 minutes to get the answer to a ques- tion is incompatible with real-life experience, the answers to the other questions would not be included in the study. One week later, the same questions were presented to DeepSeek R1 again; however, starting from the second question, the response “Server busy. Please try again later.” was received, resulting in a slower user experience. When the questions were asked for the third time on 25 February 2025, the same issue persisted, with DeepSeek R1 displaying the “Server busy. Please try again later.” message from the second question onward. ChatGPT 4.o’s eight responses were rated as “excellent” by Reviewer 1, four responses were rated as “satisfactory re- quiring minimal clarification;” nine responses were rated as “excellent” by Reviewer 2, and three responses were rated as “satisfactory requiring minimal clarification.” Gemini Flash 1.5’s nine responses were rated as “excel- lent” by Reviewer 1, and three responses were rated as “sat- isfactory requiring minimal clarification;” nine responses were rated as “excellent” by Reviewer 2, and three response was rated as “satisfactory requiring minimal clarification.” Deepseek R1 could only answer eight questions in total. DeepSeek R1’s six responses were rated as “excellent” by Reviewer 1 and Reviewer 2, one response was rated as “sat- isfactory requiring minimal clarification,” and one response was rated as “ Unsatisfactory, substantial clarification re- quired” (Table 2). The ratings given by both evaluators regarding the con- sistency of ChatGPT 4. o’s responses were found to be highly concordant (κ=0.800±0.188, P=0.0001). Similarly, the rat- ings given by both evaluators regarding the consistency of responses from Gemini Flash 1.5 and DeepSeek R1 were found to be perfectly concordant (κ=1.000±0.000, P=0.000). The average FKGL levels for the first eight responses be- tween ChatGPT 4.o, Gemini Flash 1.5, and DeepSeek R1 were found to be statistically similar (P=0.666). While no statistically significant difference was observed in terms of average FRES levels between ChatGPT 4.o, Gemini Flash 1.5, and DeepSeek R1 (P=0.053), the Bonferroni-corrected mul- tiple comparison test showed that the average FRES value of ChatGPT 4.o was slightly higher than that of DeepSeek R1 (P=0.047). (Table 3) The average FKGL levels for twelve responses between ChatGPT 4.o and Gemini Flash 1.5 were found to be sta- tistically similar, corresponding to a 10th–11th grade level (P=0.674). Although the average FRES value of ChatGPT 4.o was slightly higher than that of Gemini Flash 1.5, no statistically significant difference was observed in terms of average FRES levels between ChatGPT 4.o and Gemini Flash 1.5 (P=0.059) (Table 4). All of the documents were found to be in a format that was difficult to read. Figure 1 displays the average responses given by the eval- uators for each question that constitutes the user experience of ChatGPT 4.o, Gemini Flash 1.5, and DeepSeek R1, re- spectively, in bar chart form. It can be seen that ChatGPT 4.o and Gemini Flash 1.5 are in a very good position in terms of user experience. On the other hand, it was found that Deep- Seek R1 had a relatively poor user experience, especially in the subcomponents of effectiveness and attractiveness. Discussion In the case of chronic dermatological diseases such as AGA, the most common alopecia in the community, providing ac- curate information and effective patient education is of great importance for the success of treatment processes [12]. With patients increasingly using artificial intelligence to inform themselves about their diseases, the evaluation of both the accuracy of content generated by artificial intelligence and its usability and readability is becoming imperative. A salient finding of the present study is that while ChatGPT 4.o and Gemini Flash 1.5 were able to respond to all 12 questions quickly and without interruption, DeepSeek 4 Original Article | Dermatol Pract Concept. 2025;15(4):5929 T ab le 1 .

Lent et al. evaluated the responses of ChatGPT 4.o to questions regarding actinic keratosis, and ChatGPT 4.o received high scores in terms of speed and practicality. Another notable finding of the user survey is that Deep- Seek R1 received very low scores in the “friendly,” “enjoy- able,” and “boring” categories. In contrast, ChatGPT 4.o and Gemini Flash 1.5 scored high in these categories. As a result, ChatGPT 4.o and Gemini Flash 1.5 met user expec- tations, while DeepSeek R1 did not. Although LLMs have been around for a few years, one reason for the widespread interest in this technology is the emergence of user-friendly interfaces. Our findings suggest that language model-based AI tools should be evaluated not only for their technical ac- curacy but also for their interface and interaction features that improve the user experience. Especially in terms of pa- tient education, it is inevitable to prefer AI tools that provide fast accessible information. Accordingly, in order for Deep- Seek R1 to be more effective in patient education processes, it is necessary to make the responses fast and uninterrupted and to make interface improvements to improve the user experience. When ChatGPT 4.o and Gemini Flash 1.5 were com- pared, although both met the expectations in user experience and received valid answers for all questions, Gemini Flash 1.5 was found to be easier and more practical to use than was ChatGPT 4.o, and the former was seen as more under- standable; it was thus considered more valuable and better by the users. This resulted in a higher score in terms of meet- ing expectations. In the light of these findings, Gemini Flash 1.5 is more prominent in terms of user experience compared to ChatGPT 4.o. Table 2.

R1 experienced considerable delays in the response process commencing from the sixth question and could only respond to eight questions due to augmented response times. This de- lay resulted in DeepSeek R1 receiving the lowest score for speed and practicality in the user experience survey. Con- versely, ChatGPT 4.o and Gemini Flash 1.5 demonstrated high levels of speed and practicality. In a similar vein, a study 24 Original Article | Dermatol Pract Concept. 2025;15(4):5929 cases where the model disseminates incorrect or misleading information, this could lead to delays in seeking medical as- sistance and the misuse of over-the-counter products, result- ing in inappropriate treatment approaches. In the present study, references were appended to the re- sponses of Gemini 1.5 Flash to a number of questions. In contrast, ChatGPT 4.o did not provide references in any of the responses analyzed in this study, although it is capable of including references under the conditions specified by the algorithm. Similarly, DeepSeek R1 did not include any refer- ences in its responses. This distinction enables the evaluation of Gemini 1.5 Flash’s responses as either verifiable informa- tion or AI hallucinations, while the reliability of ChatGPT 4.o’s and DeepSeek R1’s responses becomes more uncer- tain. Additionally, DeepSeek R1’s failure to notify users of potential inaccuracies due to AI hallucinations may lead to misleading and potentially damaging consequences, as users may not realize that inaccurate or incomplete information is presented. The response of ChatGPT 4.o, Gemini Flash 1.5, and DeepSeek R1 to the question “Why does hair fall out?” was deemed to be “Satisfactory with minimal explanation re- quired” by both evaluators. This assessment was made on the basis that cicatricial alopecia was not identified as a cause of It is interesting to note that Gemini 1.5 Flash provided vi- sual materials with its answers to some questions, in contrast to ChatGPT 4.o and DeepSeek R1, which did not. While vi- sual aids can enhance comprehension, they may pose a risk for individuals with limited visual health literacy, potentially leading to misinterpretation of medical information. Further studies are needed to assess the impact of AI-generated visu- als on patient education. The phenomenon of AI hallucinations emerges when ma- chine learning models such as Gemini 1.5, Flash, ChatGPT- 4.o, and DeepSeek R1 endeavour to generate content that extends beyond the boundaries of their training data. AI hal- lucinations can be delineated as content that is not grounded in reality and is not derived from authentic data. Instead, it is the product of extrapolation or creative interpretation of a machine learning model’s training data [13]. Therefore, users of ChatGPT 4.o are notified with the warning “ChatGPT 4.o may make errors. Check important information,” while Gemini 1.5 Flash provides users with a warning that says, “Verify the answers given by Gemini Flash 1.5 as it can make mistakes.” In contrast, DeepSeek R1 does not provide any information to users in this regard. Since Deepsek R1 does not provide any warnings about potential errors, users may perceive the information it provides as entirely accurate. In Figure 1. Mean user experience ratings for ChatGPT-4.o, Gemini Flash 1.5, and DeepSeek R1, derived from the feedback of dermatology specialists who completed a user experience questionnaire on AI-assisted anal- ysis. Scores range from −3 to +3, where values between −0.8 and +0.8 denote a neutral evaluation, values above +0.8 indicate a positive evaluation, and values below −0.8 indicate a negative evaluation. Original Article | Dermatol Pract Concept. 2025;15(4):5929 25 Artificial intelligence models, thanks to their free ver- sions, provide accessible sources of information for a wide range of users. However, the readability level of the infor- mation they provide may be above the level that the general public can understand. The answers produced by ChatGPT 4.o, Gemini Flash 1.5, and DeepSeek R1, which we exam- ined in our study, were found to be at the 10th–11th grade FKGL (Flesch-Kincaid Grade Level) and were evaluated as difficult to read in terms of FRES (Flesch Reading Ease Score). However, the American Medical Association (AMA) and the National Institutes of Health (NIH) recommend that patient education materials be written at the 6th and the 8th grade level, respectively [21]. Previous studies have also shown that medical questions posed to AI models for patient education are above the rec- ommended readability level and generally produce answers at the 10th–11th grade and university level [22-23]. These findings suggest that AI-based information resources in the field of healthcare may be insufficient in terms of compre- hensibility for patients. Therefore, it is emphasised that the readability level of the information provided by artificial in- telligence models be improved and made more suitable for public health needs. Limitations This study is not without limitations. Firstly, the questions used in this study were selected based on clinical experience without the application of a standardized selection protocol, which may have limited its reproducibility and introduced selection bias. Additionally, although the accuracy of the questions was evaluated using an evidence-based approach and demonstrated high inter-reviewer reliability, subjectivity remains. Additionally, user experience is entirely subjective and based on individual evaluation. Second, each question was asked only once and in a lit- erary style. Since the quality of the input presented to the AI tools directly affects the accuracy of the responses, different answers may be generated for the same question. Further- more, as the free version of ChatGPT 4.o has question lim- itations, the system may switch to an older version (ChatGPT 3.5) during the conversation, potentially leading to different responses. Moreover, all AI tools may be updated based on new training data. Given these factors, the results obtained may differ from those of a real conversation. Third, while the rating system we used has been success- fully employed in similar studies, it is a relatively new and evolving scoring system Finally, all questions in our study were presented in English. As AI-based tools may generate responses that are influenced by linguistic and cultural factors, the generaliz- ability of the findings to other languages and cultural con- texts may be limited. hair loss [14]. Although DeepSeek R1 discusses lichen planus and lupus under autoimmune diseases, it does not sufficiently address or provide examples of scarring alopecias. ChatGPT 4.o’s response to the query regarding the onset of androgenetic alopecia was evaluated by both assessors as “Satisfactory with minimal clarification required.” Androge- netic alopecia, also known as male pattern baldness, affects both males and females, yet ChatGPT 4. o’s response exclu- sively addressed the topic to men [2]. In their response to the question “Can androgenetic al- opecia be confused with other hair loss conditions,” both ChatGPT 4.o and Gemini Flash 1.5 were deemed by Re- viewer 1 to provide a satisfactory answer that requires minimal clarification. This is because it does not mention fibrosing alopecia in pattern distribution, which is often con- fused with AGA-related seborrhoeic dermatitis [15]. The response provided by DeepSeek R1 to this question was evaluated by both reviewers as “Unsatisfactory, requiring substantial clarification.” The statement given to distinguish androgenetic alopecia from scarring alopecia, “Scarring alo- pecia involves visible damage to the scalp and is not patterned like androgenetic alopecia,” is incorrect. Fibrosing alopecia with pattern distribution was described approximately 30 years ago in a group of Australian women as a subtype of lichen planopilaris [16]. Over time, it has been reported in an increasing number of patients of both sexes [17,18]. Contrary to DeepSeek R1’s response, there is a type of scarring alopecia that exhibits a pattern distribution resembling androgenetic alopecia. The provision of incorrect information by DeepSeek R1 could lead to negative consequences for patients. This may cause delays in seeking consultation with a dermatologist and significant time loss. It should be noted that time is a critical factor in the treatment of scarring alopecia. Delayed treat- ment can result in permanent damage to more hair follicles. Furthermore, patients may incur financial losses by spending money on shampoos or hair cosmetics that have no effect on the treatment of scarring alopecia. These findings under- score the necessity for the information provided by artificial intelligence tools to undergo expert supervision before being applied in clinical settings. ChatGPT 4. o’s response to the question “How is an- drogenetic alopecia recognised?” was described by both assessors as “Satisfactory requiring minimal clarification re- quired.” The response indicated that the pull test can be used to differentiate androgenetic alopecia (AGA) from telogen effluvium. However, it should be noted that the pull test may also be positive in AGA [19]. Gemini Flash 1.5’s response to the query regarding the treatment of androgenetic alopecia was evaluated by both assessors as “Satisfactory with minimal clarification.” Gem- ini Flash 1.5 did not mention platelet-rich plasma treatment and was therefore assessed as such [20]. 26 Original Article | Dermatol Pract Concept. 2025;15(4):5929 References 1.
