TLDR UVA damages all hair types, especially permanently waved and colored hair.
The study examined the impact of ultraviolet A (UVA) on virgin, permanently waved, and colored hair, finding that UVA exposure caused damage across all types. The most significant damage was seen in permanently waved and colored hair, with effects including reduced tensile strength, loss of elasticity, and color changes like increased brightness and decreased chroma. The study recommended using sunblock products for all hair types and specialized shampoos for colored hair to reduce UVA damage. It also noted the potential for increased hair damage due to global warming and environmental issues, stressing the importance of protecting hair from UV rays.
