Studysummary In this study, researchers found that UV radiation causes hydroxy radicals to form cuticle holes specifically between the cuticle layers in wet hair, unlike random holes caused by Fenton's reaction.

The study concluded that UV radiation caused significant damage to human hair by creating cuticle holes and peeling off cuticle layers. This damage was attributed to the oxidation of linoleic acid, a polyunsaturated fatty acid present between the cuticle layers, leading to the production of highly reactive hydroxy radicals. These radicals were responsible for forming cuticle holes and overall hair damage. The findings emphasized the importance of protecting hair from UV exposure to maintain its structural integrity and appearance.
