1. Don't Wash Your Hair Everyday. Washing the hair daily may cause the oils to be stripped too quickly, encouraging them to come back as even oilier to make up for the loss. If you have naturally greasy hair, it's recommended that you only wash it every 2-3 days.
2. Avoid Chemical Based Shampoo, Conditioner and Styling Products. Most hair products contain chemicals that are effective at cleaning your hair but may cause much damage. Sodium laurel and laureth sulfates are cleaning agents found in most shampoos. They strip the hair of natural oils and cause hair to weaken and fall out over time. Try using Organic products like Aveda and Ojon.
3. Use Essential Oils to Thicken your Hair. Our scalps produce natural oils that coat the hair and protect it from outside damage. When these oils are washed away every day, the hair becomes weaker over time. I use Jose Maran Argan Oil (2 pumps and use it in the bottom half of my hair after a shower when it's still wet, it helps with the breakage and keeps the hair shiny also) If you're hair is more oily than use a “dry shampoo” to treat your hair in between washes. It keeps it looking fresh and has the added benefit of making hair look thicker. Dry shampoo is a powder you can comb through your hair, especially around the roots, between washings.
4. Do NOT Brush Your Hair When You Get Out of the Shower! It breaks the hair. If you insist on combing, use a wide-toothed comb instead of a brush, and work out the tangles with care after it, rather than pulling them through. Be especially gentle when your hair is wet. Don't towel it dry roughly or wring it out, since this may cause some hairs to break. Use a towel to gently squeeze and pat your hair dry instead.
5. Heat is a KILLER. Avoid heat styling tools. Use blow dryers, straight irons, and curling irons sparingly. Overusing heated hair appliances causes your hair to become dry and brittle, making it fall out much more easily. You can blow dry it on cold until it's mostly dry then move to warm not hot on the dryer if you must.
6. Try Volumizing Techniques For a Fuller Appearance. There are many volume-boosting products on the market. Go for the ones with natural ingredients. Try using root lifters and volumizing sprays when styling your hair to get the fullness you are looking for.
7. Trim Your Hair Every 4-6 Weeks. Cutting off dry, dead ends adds new life to hair, making it appear thicker.
8. Take Vitamin B or Hair, Skin, Nails Supplements. Many people experience thinning hair because they have nutrient deficiencies. Eat a well-balanced, healthy diet with plenty of vitamin B and iron. Vitamin B plays a large role in the health of your hair, and getting enough of it is essential to keeping thick hair and reducing how much you shed. Good sources of vitamin B include fruits, vegetables, nuts and brown rice, among others.
9. Keep Your Stress Level Down. Stress often leads to hair loss. If you have a source of stress you can remove from your life, consider doing so.
