If you are like me who does not believe in dumping all kinds of products on your skin and hair and believe in being natural, you can rub 4-5 drops of sesame oil (known as Gingelly oil in India) on your palms and finger comb your hair. Pay more attention on the ends. Sesame oil, not only blocks sun rays, but also keeps your hair smooth and shiny. You can also mix sesame oil with some coconut oil and lavender (or rosemary) essential oils. It will ensure healthy growth of hair.
