Pubic atrichosis or hypotrichosis is a condition of abnormal pubic hair growth - usually a reduction or full loss of hair.
The condition is thought to be very common among Korean women of Mongolian descent. While in the west many women spending ridiculous amounts of money to try and permanently reduce or remove their pubes, in Korea, some are spending grands on pubic hair restoration surgery, or pube transplants.
Pubic hair reduction and loss is a normal part of ageing and also can occur in alopecia universalis. If you experience a random reduction or loss of your pubic hair you should speak to your doctor right away.
