How Long Does Laser Hair Removal Last?


Using lasers, unwanted body and facial hair can be removed non-invasively.

Permanent or near-permanent results can be obtained with laser hair removal on the body for some people.

Some people see a smaller amount and thinning of regrown hair over time.

The face rarely achieves permanent results, and regrowth may take years.

Several factors affect the results. Treatment areas and fluctuating hormone levels are two examples.

When will hair begin to grow back?

In the course of laser treatments, you will still see hair. There is some regrowth, but a great deal of it is untreated hair.

It may be many years before you see regrowth following your treatment course.

Laser hair removal on the body can provide permanent or extremely long-lasting results. The hair that does regrow overtime should be thin and fine.

When laser hair removal is done on the face, it is not typically permanent, but can last for years.

After 10 years or more, some people have no hair left. Those who experience regrowth sooner require touch-up treatments annually in order to maintain hair-free skin.

After laser hair removal, hair is most likely to return to areas such as the chin, neck, and other areas of the face.

Dehydroepiandrosterone (DHEA) and testosterone can stimulate hair follicles to grow.

The hair on the chin, neck, upper lip, and sideburns can regrow when estrogen levels drop during menopause.

The body can also regrow hair. In some individuals, the bikini line, stomach, or underarms may be more likely to be affected than the arms, legs, or chest.

Does hair or skin color make a difference?

You may have less success with laser treatments if you have dark hair or light skin, but once the treatment is complete, your hair will grow back at the same rate.

The laser cannot remove hair from blondes, whites, and grays.

Having laser treatments touched up as necessary can curtail hair regrowth.

Another option is electrolysis if the growth of hair is sparse. Rather than treating whole areas at once, electrolysis treats individual hairs.

When you have polycystic ovarian syndrome (PCOS), maintaining your hormone balance can help prevent hair regrowth. By taking medications like Metformin or modifying your diet, such as eating fewer carbohydrates, you can balance these hormones.


Laser hair removal is long-lasting and removes unwanted hair from the face and body. It can sometimes produce permanent results. Laser hair removal is more common on the body than on the face.

Hair regrowth can also be caused by hormonal fluctuations for some people.
