Once a month (usually the night before I plan to wash my hair) I drench my whole head with coconut oil and let it sit overnight. I rub the oil into my hands, comb the oil through, braid my hair, and sleep on it. Although the coconut oil will wash out of your bed linens I usually like to put an old pillowcase that I don’t use on the regular just in case. In the morning when I wash my hair I shampoo twice then condition as usual. My hair is left feeling silky smooth and I swear it has helped my blonde, treated hair stay healthy!
