Coola SPF 30 Scalp and Hair Sunscreen Mist, Vegan and 70 Percent + Organic, Protects Scalp and Hair from the Sun, Suitable for All Hair Types

I bought this because I kept burning my scalp where my hair parts in the middle, and hats don't suit me at all. I struggled to find many alternative products specifically aimed at your scalp, so went for this even though it felt quite expensive. However I am glad I did, it definitely works as I haven't burnt my scalp since and I've been using this product for a couple of years now. Although the bottle is small, it lasts for quite a long time as all you need is a few sprays each time, so it's better value for money than I originally thought.It does make your hair feel slightly sticky but it's not too bad at all.

Leaves major buildup in hair and also dries it out?

Made my hair greasy not good

This smells nice and seems to make my hair look thicker. I use it on and around my parting.
