Age‐related changes in scalp biophysical parameters: A comparative analysis of the 20s and 50s age groups

Abstract Background Age‐related changes in scalp parameters affect hair quality and condition. However, detailed data on biophysical of the across age groups remain scarce. We aimed to investigate differences between individuals their 20s 50s analyze sex‐specific variations. Materials methods Two hundred participants (160 women 40 men) were equally divided into groups. Biophysical scalp, including elasticity, pH, trans‐epidermal water loss (TEWL), sebum production, desquamation, firmness, redness, yellowness, measured vertex, occipital, temporal regions. Hair density thickness region. The accumulation advanced glycation end products (AGEs) skin was noninvasively a subset 60 women. Results Skin firmness redness increased with women, whereas yellowness both sexes. Sebum production pH levels significantly lower group than group, particularly TEWL men those 20s, occipital A significant reduction observed AGE correlated yellowness. Conclusion have important implications for health These findings emphasize importance considering sex when developing care strategies.
