10 Surprising Products with SPF

Our verdict: Total fluke

Why: According to Danesh, “the hair is not a viable tissue [like the skin is].” So while the sun can penetrate through the hair cuticle, it won’t cause harmful damage to the hair because it doesn’t have live cells. This means “there is simply no added benefit to using hair conditioner with SPF,” says Danesh. It does have other pros, such as “nourshing and detangling strands, preventing frizz and enhancing shine,” says NYC-based hairstylist and makeup artist Kim Gray. But when it comes to actually protecting your hair from the sun, conditioner with SPF is a total fluke.
