What causes changes in hair texture?

Dr. Mehmet Oz, MD

Many factors can cause your hair to change in texture. Changes in hair texture are common during pregnancy, when hormones may also cause hair to fall out less and grow faster. Hormonal imbalances can cause normally soft body hairs in women to become coarse, dark, and noticeable. Changes in hair texture can also be caused by certain health conditions. Dry, brittle hair, for instance, can be caused by an underactive thyroid gland. A poor diet can also lead to dry and brittle hair.

Of course, how you take care of and style your hair can also affect its texture. Perming, relaxing, and dying your hair all can change how the hair looks and feels. Curling irons and flat irons, which both use heat, can also change hair texture, although the result is usually temporary.

Consult your doctor if you notice any sudden or unexplained changes in the texture of the hair on your body or head.
