Walnut oil is very rich in omega-3, omega-6 and omega-9 fatty acids, all of which are essential for strong, healthy hair. Omega fatty acids are vital for keeping hair strands shiny, nourishing the hair shaft, encouraging hair growth, and fighting against a dry and flaky scalp.
Omega-3 fatty acids are not naturally produced by the body and are typically found in various foods, making them solely available through consumption. Walnut oil is also becoming popular for its anti-fungal benefits, which are so effective that they are believed to have the ability to kill lice. To use walnut oil as a hair treatment, apply a generous amount of the oil to the ends of hair and massage into the scalp. Let the oil penetrate the hair and scalp for about 20 minutes, and then shampoo and style as usual.
