Thinning hair and hair loss strike both genders — approximately one-third of women will suffer from alopecia at some point in their lives, while two-thirds of men will have experienced significant hair loss by age 35. Thinning hair stems from a variety of causes, including the natural aging process, over-styling (known as traction alopecia) and simple genetics.

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.

Foods rich in biotin include nuts, eggs and fish, which are also high in hair-promoting protein, as well as mushrooms and legumes. Vitamin E-rich foods include almonds, spinach, sweet potatoes and avocados, the latter of which also containing healthy fats that can help with hair health.
