Hirsutism is a medical condition that results in excessive hair growth in women, typically on the chin, upper lip, chest, and abdomen. It is caused by an increase in androgen hormones, such as testosterone, which can be due to various underlying medical conditions, most commonly polycystic ovary syndrome.

Laser hair removal works by targeting the pigment in the hair follicle with a focused beam of light. The heat from the laser damages the follicle, inhibiting or delaying future hair growth. While laser hair removal can effectively reduce or even eliminate hair growth in these areas, it should not be the only treatment modality for hirsutism. The underlying hormonal imbalance needs to be addressed through medical treatment like oral contraceptives and other medicines to reduce the androgen excess, which will make the effects of laser better and longer lasting.

Do note that may take multiple sessions, more than average, to achieve the desired result and maintenance treatments may be necessary.

In conclusion, while laser hair removal can be a useful tool in managing the symptoms of hirsutism, it should be used in conjunction with medical treatment to address the underlying hormonal imbalance.
