This Native Brazilian hair secret combines ox marrow (tutano do boi) with other natural or cosmetic ingredients:
I. pure ox marrow
II. needs to be boiled
III. let it cool a little bit
IV. mix it with either conditioner or other hair creames
V. mix it with natural hair-loving ingredients such as avocado
Apply it to semi-wet hair, cover with a plastic cap (or bag from the supermarket ;) and let it sit for about an hour, if possible put a hot towel on it or relax in the garden sun... Then remove it with shampoo and condition as normal.
This traditional recipe is incredible for moisturizing dry hair after a long day at the beach just be careful to not get everything greasy - best thing might be to use plastic gloves ;)
