Your hair may be thinning for a variety of reasons, including natural aging, disease and over-styling (traction alopecia), according to the Mayo Clinic. If your doctor has ruled out serious medical conditions, she may prescribe medications or procedures to help with thinning hair. If you want to thicken your hair at home, you can try some natural remedies to increase your hair's volume to give the appearance of thicker hair.
Get your vitamins. According to Dr. George Obikoya, of the The Vitamin and Nutrition Center, hair follicle cells have specific metabolic requirements that must be met for optimal hair growth. Without the right vitamins and minerals to meet these requirements, hair growth, thickness and quality can be affected. You can get the right vitamins by looking for multivitamin products that provide vitamin B-6, inositol, folate, biotin, vitamin C, vitamin E, zinc, magnesium and sulfur.
Use essential oils with aromatherapy. According to research done by the Aberdeen Royal Infirmary in Scotland, massaging essential oils in the scalp, such as those from lavender, rosemary, thyme, jojoba, grapeseed and cedarwood oils, may be able to help regrow hair, adding to the overall thickness and volume. You can buy essential oils at most homeopathic or naturopathic stores.
Put 2 tbsp. oat flour in your conditioner. Oat flour contains important lipids that can thicken the brittle strands of hair on your head, giving you the look of fuller hair.
Beat a single, large egg and massage it into your hair, being careful not to get any of the egg into your mouth or eyes. Let the egg sit for five to 10 minutes and then rinse. Do not use hot water to rinse or you may cook the egg in your hair, making it difficult to remove. Eggs provide essential vitamins and proteins believed to strengthen and thicken brittle hair.
Avoid harsh hair treatments, such as pulling your hair back in a ponytail and using a flat iron. Use a lower heat setting on your hairdryer, and using natural products or products with little or no harsh chemicals, can help protect your hair from further damage and thinning.
