The document discussed how pregnancy and hormonal contraceptives could lead to hair loss on the scalp and increased hair growth on the face and body in women. These changes were generally temporary and resolved without treatment, except in rare cases of virilization caused by nortestosterone-containing antiovulation drugs, which could lead to androgenetic alopecia and hirsutism. The studies indicated that gestagen might cause temporary disruptions in the hair cycle, increasing the number of telogen (resting) hairs or decreasing the induction of anagen (growing) hairs.
