My hairs were dark black, now its bit brownish and dry. I apply coconut oil, which helps but shows up a lot of scalp. I'll have to go for a matte look greasy product.
I'm a 25 yr old guy with diffused thinning. I have black hairs, but they are not dark enough,looks a bit brownish. I eat a balanced diet. Any supplements which can improve the quality of existing hairs?
