Did you mean Photoprotective?

Glossary Photoprotective

Photoprotective refers to the ability of certain substances or mechanisms to protect the skin and hair from the damaging effects of ultraviolet (UV) radiation. In the context of hair loss and hair biology, photoprotection is relevant because UV exposure can lead to oxidative stress, which may contribute to hair follicle damage and hair thinning. Key distinguishing characteristics of photoprotective agents include their capacity to absorb, reflect, or scatter UV rays, as well as their role in preventing inflammation and promoting overall scalp health.
