Sunscreen use in hair care products is limited since most sunscreens are not substantive. Hair is a nonliving structure.

Hair Care ProductSunlight, wind, air, pollutants, and chlorine in swimming pools can be susceptible be damaging agents. Although nonliving, these agents can cause damage to the hair fiber, and this must be prevented at great expense, especially treated or relaxed hair.

The use of anionic polymers polyquaternium 59 and butylenes glycol significantly increased the sun protection of the hair.

This next formula is a sunscreen spray formulated especially for the hair. This formula doesn’t contain sunscreens, and the product is not an OTC drug, but a cosmetic, and will not require any OTC testing as long as the claims are carefully thought out.
