I have what I think is coarse hair and protein works great. I do weekly protein treatments and balance with moisture the rest of the week. I used Bone Marrow protein treatment for years and my hair was at its finest (I would balance with Aussie moist shampoo). Nowdays I am far away from the US and can't find Bone Marrow, however I am using Mega-Tek which is protein based and my hair is thriving again.
