Rich in protein and probiotics, yogurt is another great hair natural treatment that can repair damaged hair and stimulate hair growth. Depending on the length of your tresses, you’ll need approximately half a cup of yogurt. Apply it to your locks and wrap them in a towel for 15 minutes. When you use yogurt, it’s important to rinse the residues away thoroughly. By adding an egg to the yogurt you’ll increase frizz reduction and get more manageable tresses.
