Dry, frizzy hair is often caused by excessive styling using harsh chemicals or heat. Some medical conditions may also contribute, such as malnutrition, anorexia or an underactive thyroid. Sometimes, dry hair is a product of your genes. Your scalp may naturally produce few oils, which keep your hair healthy. Or you may live in a dry environment. Help your hair recover by avoiding harsh styling and chemical treatments. Provide moisture by using an appropriate cleansing routine and applying hot oil hair treatments on a regular basis.

Things You'll Need

Visit your hair stylist for a trim if you have split ends. You can prevent split ends, but not cure them if you already have them. Trimming them off can prevent the hair shaft from splitting further.

Avoid activities that can damage your hair. Do not use devices like hair dryers, curling irons and straightening tools, and avoid coloring your hair or having a permanent done. If possible, avoid swimming in chlorinated water. Chlorine takes the sebum, or natural oils, out of the hair shaft. This leaves hairs vulnerable to splitting.

Shampoo your hair every two to three days. Use a shampoo with a low pH, as recommended by Women’s Healthcare Topics. Gently massage the shampoo into your scalp; avoid rubbing the hair vigorously.

Condition your hair each time you shampoo it. Turn the water in the shower off and towel dry your hair before applying conditioner. Leave the conditioner on for about three minutes. Comb through your hair very gently to spread the conditioner. Then rinse off with cool water to help seal the hair’s cuticle.

Apply a hot oil treatment to your hair every couple of weeks. Heat 2 tbsp. olive oil in the microwave for about 10 to 15 seconds. Test it with your finger to ensure it won’t burn your scalp. If it’s too hot, allow it to cool.

Massage the oil into your hair, distributing it evenly. Wrap your hair in a damp towel, turban-style. Allow the oil to work for about half an hour, then rinse it out.
