Oct 10, 2014 - I would have to say that the Jamaican Black Castor Oil is my fav shampoo from Shea Moisture. I have a scalp condition that I believe may be seborrheic dermatitis. I normally have to wash my hair every 3-4 days because of the thick patches and itchy scalp. Since using this product, I can go up to 9 days without washing my hair! It doesn't strip my hair even though it's a clarifying shampoo.(I can't say that about the shampoo from their black soap line though.) Afterwards, my hair and scalp is thoroughly cleansed and moisturized.
