Dry hair usually owes it's texture and dullness to raised cuticles on the hair shaft. In healthy hair, these cuticles lie flat, lending the hair a healthy sheen and making it smooth and manageable. These flat cuticles also help to keep moisture inside the hair. When cuticles are raised, the hair is more porous and moisture escapes relatively easily.

Understanding the underlying cause of dry hair is the first step towards knowing how to care for it.

Dry hair is characterized by dullness, a dry or rough feeling, split ends, frizz ness, and it is often difficult to comb or brush. Dry hair is frequently caused by excessive or amateur coloring or perming, heat-assisted styling (using hair dryers, straightening tools, curling tongs, etc) and exposure to sun and chemicals. However, some people do have hair that is naturally dry.

Dry hair occurs when your scalp produces a less than average amount of oils to
naturally moisturize the shaft. Either you have few oil glands, or the glands produce a low amount of oil; dry hair is not influenced by hormones. Dry hair tends to occur in the darker shades, and it holds a style for along time. Dry hair does not respond well to perms or coloring and will become brittle due to water loss unless great care it taken.

1. Use a shampoo with a rich emollient that will clean and soften your hair.

2. If you have dandruff, use a shampoo with coal tar .

3. Naturally dry hair, unlike dry hair caused by processing or coloring, is not weak or brittle, so you can use a conditioner that contains ingredients like ammonium salts to make your hair soft and manageable.

4. If the ends are extra dry, look for a conditioner with protein or balsam

5. For styling products, look for alcohol-free ones.

6. After you’ve washed, conditioned, added styling product, and dried your hair, rub a little facial moisturizer onto your palms and run them through your hair. Then brush your hair to distribute the moisturizer. 

7.Fine, straight hair usually contains too much moisture. This is why the hair lays flat and limp. It is important to keep the hair clean and dry. 

8. If your hair is fine and not chemically treated, get your stylist to recommend a good shampoo for fine hair and forgo the conditioner. Once a week protein treatments work wonders. 

9. If your hair is fine and chemically treated, permed or colored, use a shampoo for fine hair and a conditioner that will work on the inside of the  hair. Use the conditioner more on the lengths of the hair and try to keep it away from the scalp. If the roots are free of conditioner, the hair will be fluffier.

10. To style fine hair, first blow-dry the hair trying to get more volume at the roots. Use a light styling lotion to create volume without weighing the hair down.

11. For a fancier, fuller look, use Velcro rollers on pre-dried hair and a light hair spray and apply heat. Hot rollers are excellent also.

12. A good haircut to remove split ends is highly recommended. Ask your stylist to recommend a haircut that will compliment your fine hair and suit your features.

13. Very long hair is usually not recommended for fine, thin hair. If you must wear it long, keep the ends blunt and use a protein treatment once a week. A colour or perm usually adds body to fine, limp hair

14. If your hair is dry, wash it twice a week with a shampoo for dry hair, followed by a conditioner. If your scalp feels very dry and flaky, use an anti-dandruff shampoo. Be very gentle with the ends of the hair, which are the driest parts and tend to split easily. You may be tempted to use styling products to tame the frizz, but avoid it. Frizz is usually caused by the inadequate flow of sebum from the roots, as it is being blocked by the flaky scalp. Give your hair a good oil massage before washing, to loosen the flakes, and rinse hair extra thoroughly.

15. Do you spend a lot of time in the strong sunlight? Try using a suitable hair sunscreen or protecting your hair with a headscarf or hat during the hottest parts of the day.

16. Do you use your hair dryer on a high temperature often? Try allowing your hair to air dry wherever possible, and when it is necessary to use your hairdryer, use it on a cooler temperature and aim it down the hair shaft (pointing down from the top of your head). This is because your hair cuticles are naturally aligned away from the scalp. Make sure you move the hairdryer around when you're using it rather than leaving it concentrated on just one section of your hair.

17. Additionally you can use a conditioning treatment specifically designed for use with heated styling tools. A good conditioning treatment will limit the damage that they inflict.

18. A through brushing of the hair using a slow, gentle, even strokes to minimize pressure on the split ends every day keeps it free from unwanted particles and helps to bring the natural oils from the scalp to the hair split ends. This will make your hair less dry and brittle and will help it to look silky and lustrous.

19. Avoid sun damages, chlorinated swimming pools by wearing hats and swimming caps.

20. Avoid shampoos that are extremely alkaline or that contain alcohol.

21. Keep split ends or dead hair cut. In most cases you cannot repair the damage by treating hair from the "outside-in." Hair has to be repaired from the "inside-out." Keeping the hair healthy and free of dead and/or split ends will help new hair grow faster.

22. Use the jojoba oil and rosemary mixture on your hair once a week. This can be applied overnight (wear a cap or use a old pillow case) or use as a hot oil treatment under the hair drier

23. Eat a high protein diet, drink water, and stay away from hair coloring, junk food, and chemicals.

24. Heading into the pool? 
Have a quick shower first, being sure to thoroughly soak your hair. This will stop your hair from soaking up too much chlorine, which can leave your hair dry and brittle.

25.Does your skin seem drier lately? 
It could be that antihistamine you're taking. Antihistamines "dry up" your nose but it can also have a drying effect on your skin and hair. Remember to moisturize often and try using a moisturizing conditioning mask on your hair.
