Why: Again, hair is not a viable tissue, so “it is not worth buying UV protection sprays for the hair [for that same reason],” says Danesh. However, if you have colored hair, it is worth buying — the UV protection in the spray will protect and prolong your hair color under the sun, says Gray. But if you’re just worried about your scalp burning, you’re better off using a sunscreen spray, which “is still beneficial for protection of the scalp,” says Danesh.
