If you've ever had your scalp burnt, then know you how miserable it is. Normally relaxing things like brushing your hair or taking a hot shower, turn into dreaded chores.
Having light and thin hair, it happens to me often. Using normal spray sunscreen leaves your scalp/hair greasy and sticky, and that is no fun. I'm surprised I've gone 30 years without purchasing an actual scalp sunscreen, but I am about to bite the bullet.
Here are some that I found online that received good reviews.
Let me know if you've tried any, or what your favorite is!
