Dry hair: 5 main causes & 8 key treatments

Save Share

Did you notice that your hair has become dry and lifeless? The reasons may be hidden deeper than just in your hair care products. Let’s take a closer look at the problem and find ways to fix it.

Your hair can get dry because your scalp isn’t making enough oil to moisturize your hair. In fact, with age, your hair naturally makes less oil.

A dry scalp peels and sheds, leading to dandruff flakes on your shoulders.

Your hair may get dry because moisture escapes from your scalp.

Each strand of healthy hair has a protective layer called the cuticle that shields your hair from heat and sun damage. In a healthy cuticle, the layers lie tightly together and keep moisture in. When a cuticle’s layers separate and peel away from the hair, its ability to hold moisture is compromised.


5 causes of dry hair

  1. Heat treatment: you blow dry your hair too often, use heated hair straighteners or irons
  2. Environment. Hot, dry climate. You expose your hair to lots of sun, wind, or dry air, and/or swim in chlorinated or salt water
  3. Chemical treatments. Alcohol-based styling products, harsh shampoo that takes away natural oils. You apply dyes, perms, and relaxers
  4. Poor nutrition. Calcium is a key nutrient for healthy hair, as well as bones, teeth, and other tissue.
  5. Health conditions: Anorexia nervosa, hypoparathyroidism, hypothyroidism, etc.

How to fix dry hair

  1. Wash your hair less often, like once or twice a week
  2. Use a mild shampoo for dry hair with fewer drying detergents.
  3. Use hair products that don’t have alcohol in them because it dries hair out.
  4. Use a moisturizing conditioner to keep cuticles lying flat so they hold in natural oils.
  5. Apply coconut or jojoba oils into your scalp with a massage
  6. Improve your nutrition to get all the necessary supplements
  7. Cover your hair to avoid sun and water exposure
  8. Check with your doctor for possible thyroid issues

If your dry hair occurs with fatigue, intolerance to cold, weakness, or hair loss, see your doctor to make sure you don’t have a health problem.
