Medical Reasons for Axillary Underarm Hair Loss in Males

Testosterone and dihydotestosterone, shortened to DHT and even stronger than testosterone, are both androgens or male hormones. These hormones determine male characteristics, including how much, or how little, hair a man will have.

Aging

• As a man gets older, his androgen (male hormone) levels decline. When this occurs he can lose axillary or under arm hair as well as pubic hair. Both are dependent on testosterone for growth.

DHT

• DHT binds to receptors in your body and then travels into cells, interacting with the center of the cell, which alters the production of protein. This result is cessation of hair growth.

Effects

• DHT contributes to the shrinkage of hair follicles and a decrease in visible hair.

Addison's

• According to Cureresearch.com, a condition called Addison’s disease can result in hair loss. This disease is a rare autoimmune disease of the adrenal glands.

Treatment

• Treatment for Addison’s includes replacing the hormones that the adrenal glands aren’t capable of producing. You may be given hydrocortisone to replace cortisol as well as mineralocorticoid.
