The link between the Morning-after Pill and Hair Loss

The morning after pill otherwise known as the emergency pill has been linked to hair loss in women. Studies have shown that androgenetic alopecia which is a female pattern baldness is prevalent in women using the morning-after pill.

Androgen is the male hormone responsible for hair loss in both men and women. Testosterone, a common androgen, converts to dihydrotestosterone (DHT) naturally on certain body tissues including oil glands of the hair follicle. The result of this action is thinning of hair follicles and fall out of hair eventually. Women experience gradual thinning of hair because they have small traces of androgen naturally. But, this is not the case with the ladies using the morning-after pill.

The morning after pill constitutes of two hormones; progestin and estrogen. The formulation of progestin has a high androgen index. Therefore, the androgen in progestin converts to dihydrotestosterone which binds to hair follicles and causes hair loss as mentioned above. Estrogen, on the other hand, stimulates the conversion of androgen (testosterone) to DHT. This elevates the levels of DHT, resulting in more hair loss.

Hair loss as a side effect of the morning-after pill cannot be avoided. There are products available in the market that can control hair loss caused by DHT. Hence, women using the emergency pill should no longer worry about hair loss.
