If you have dry hair, try shampooing it only 2-3 times a week instead of every day. If doing so makes your hair look oily between washings, spray your roots with dry shampoo, then comb it through to the ends of your hair. Each time you shampoo, use a conditioner made with natural oils to nourish your hair. Once a week, apply a deep conditioner to your hair and leave it on for at least an hour. Whenever you can, avoid using heat to style your hair, since heat can dry out your hair more

Handle your hair gently when you wash and dry it. 

 If you have dry hair, you have fragile hair. Handling it roughly will cause your ends to split and could even lead to breakage. When you're washing, drying and otherwise handling your hair, think of it as a delicate fabric that needs to be treated with extra care. That means no scrubbing, pulling or wringing it out.

• When you shampoo your hair, use the tips of your fingers to gently pull the shampoo through your hair instead of roughly scrubbing it in.
• Rinse your hair using cool or lukewarm water; hot water is extra damaging to dry hair.
• When you're done, gently squeeze excess water from your hair instead of twisting and wringing it out. Pat it dry with a towel.

Hair becomes dry when the natural oils produced by your scalp aren't getting the chance to nourish it. Shampooing dry hair every day will make it ever drier and more brittle since you're stripping those oils away on a daily basis. Cut back to shampooing just two to three times a week, to give your hair the chance to receive those nourishing oils.[1]

• When you first cut back, you'll notice your scalp producing a lot of oil, since it's used to having to overproduce to make up for how much gets washed out. Give it a week or two and you'll find that things balance out; you'll be able to go several days in between washings without your hair looking dirty.
• If your roots start looking a little oily, dry shampoo is a great way to remedy the problem without washing your hair.

Apply a quarter or dime-sized amount of conditioner, depending on the length of your hair. You want to use enough to coat the strands of your hair without weighing it down. Gently massage it through your hair, focusing on the tips, and rinse out with lukewarm or cool water.

• If your hair is extremely dry, you might want to consider a leave-in conditioner as well. This will protect your hair from drying out during the day, helping it stay shiny and manageable.
• If your hair looks dull and lifeless after conditioning, you might want to switch your conditioner. Look for one made with nourishing natural oils and free of silicones.
