How long does laser hair removal last?
Disease description:
I have always been troubled by my hirsutism. I heard that laser hair removal can provide long-term reduction of hair growth, but I'm not sure how long the effect will last. I would like to ask the doctor, if I undergo laser hair removal, how many years can this smooth condition be maintained?

In general, laser hair removal can provide a hair reduction effect lasting from six months to three years.
Laser hair removal is a cosmetic procedure that uses laser energy to destroy hair follicles, thereby achieving long-term hair growth reduction. The longevity of its effects is influenced by multiple factors, including individual skin type, hair color, treatment area, and procedural details during treatment.
For patients undergoing laser hair removal for the first time, if they have a faster metabolism, more active hair follicles, and a smaller treatment area, the results may last a relatively shorter time, usually between six months to one year. However, if advanced laser hair removal equipment is used, and the patient has previously undergone laser hair removal with a slower metabolism, the effects may last longer, up to three years, and in some rare cases, may even achieve permanent hair removal.
The duration of laser hair removal also depends on the treatment area. For example, areas such as the face, where the hair is finer and has a shorter growth cycle, may experience relatively shorter-lasting results. In contrast, coarser-haired areas such as the legs may yield more prolonged effects.
