I agree! sun stroke and skin cancer are no jokes! I always hated putting sunscreen on my head when I wore a horseshoe flattop and that is one of the great benefits of choosing to go fully sly.
I use a great sunscreen that comes in a spray, goes on almost dry, is never "greasy", doesn't get effected bybsweat and roll down my forehead, and is almost waterproof. Comes in five different SPF's
Nutrogena Sheer Mist spraybsunblock. I use it every day on my scalp!
