This is really not an academic question. You might want to consult a professional hairdresser who could discuss possible style and care options with you.
You can use argan oil which is great for treating dry hair, you can use it on your hair, nails, and skin as well(you can buy it at sephora for $14). Also, the new craze is the "No Poo" movement. This means not shampooing hair but instead conditioning it daily. If you must use a shampoo, try to use creamy ones instead of clear ones. When it comes to conditioner, you should use it everyday and then use a deep conditioner once a week. If your hair is frizzy, try not to overuse the blow dryer because it tends to dry it out. Finger comb your hair and let it air dry, you can use paper towels to squeeze the moisture out instead of rubbing your hair with a towel. Hope that helps!
if ur hairs are dry and curly u should put oil in ur hairs and wash ur hairs with dove shampoo and use conditioner on ur hairs they will become straight and use conditioner and shampoo both of dove company only
