Treating Dry Hair:

If your hair looks dry and lifeless. This type of hair craves moisture, and in most instances requires a healthy dose of protein. Dry hair needs protection in the form of emollients and lubricants, which will lay down the outside cuticle layer of the hair and create the shine you want. Humectants will attract and retain moisture within your hair. Moisturisers  contain humectants that not only replace lost moisture but actually attract moisture and retain it in the cortex of the hair. Daily shampooing and conditioning with mosturizing and emollient treatments will go a long way toward alleviating a dry, tight scalp, while  replenishing lost moisture and proteins  along the hair shaft. Try using moisturisers, which have humectants in it. Essential fatty acids are great moisturizers. One of the best and most cost effective essential fatty acids is safflower oil. The scalp produces the best essential fatty acid called sebum but sebum cannot reach upto the entire length of the hair, especially if it is long.
Take a few drops of safflower oil in your palms while the hair is dry apply to the ends and then work toward your scalp. By applying safflower oil your dry hair will have the proper amount of humectants to attract and retain moisture. If possible leave in your hair at least 2 hours. Use a moisturizing shampoo  and conditioner on your ends only every other day. Rinse with water alone on off days.. When you're at beach, spread some of the sunscreen use on your body through your hair so that it doesn't dry out and get fried from the sun.
