Comparison of hair shaft damage after UVA and UVB irradiation.
Sunlight, especially ultraviolet (UV) light-induced hair damage is difficult to avoid during daily life. Concerns about the effects of ultraviolet light on hair are emerging recently. These photochemical changes mainly come from damage to hair proteins and melanins. In this study, we performed experiments to find the patterns of morphological and biochemical changes in UV-light-induced damage to hair by scanning and transmission electron microscopy and hair protein analysis. In our results, morphological damage is significant in UVB-irradiated hairs, while biochemical changes are greater in UVA-irradiated hairs.
