How Long Does Laser Hair Removal Last?

How long does laser hair removal last: Knowing the duration of the treatments and each of the sessions that make it up is one of the most common doubts among those who decide to try permanent hair removal for the first time. Still, there is no one-size-fits-all answer, as it depends on various variables, such as the amount of hair to be removed and its characteristics or skin type. You will find indicative data in this post if you want to know how long a laser hair removal session lasts (approximately).

In addition, you will learn which session gives you visible results and how effective the diode or alexandrite laser we offer you in Grupostop centers is. Pay attention! Permanent hair removal with pulsed light has potential adverse effects, ranging from burns to eye damage. The National Agency reports this for Health Security which warns of the lack of supervision around the sale of devices allowing this practice. Available on the market for several years, they make pulsed light hair removal accessible at home and no longer reserved for doctors. There would be a danger.

As you know, the main advantage of laser hair removal is that it is a permanent hair removal method that allows you to get rid of unwanted hair once and for all. Of course, a single day is not enough for this, but usually, between six and 14 sessions are necessary for each area to be treated.

The duration depends on the following physical characteristics of each person, and they are the following.

  • Skin tone classified into six phototypes
  • The type of hair or hair, depending on its color, thickness, and density
  • The extent of the part to be depilated and the thickness of the skin covering it

Taking these three variables into account, although at Grupostop, we always carry out a preliminary study for each person to offer personalized treatment, we summarize the approximate duration of a laser hair removal session in each area of ​​the body.

From Which Session are the Results Visible?

Another doubt among those who wish to avail of treatment is its effectiveness. In this sense, you can have peace of mind because the results of laser hair removal are visible from the first session. We recommend this article on how hair disappears with laser hair removal to learn more.

In addition, you will appreciate not only a decrease in hair but also much softer skin. The light of the alexandrite and diode laser stimulates collagen production, significantly improving the dermis’s elasticity and luminosity. Therefore, you will get rid of those unsightly hairs and achieve a rejuvenating effect without surgery. What happened if?

However, we must not forget that permanent or permanent hair removal occurs in the medium or long term. The total duration of the laser treatment depends on the amount of hair to be removed and the physical characteristics of each client.

Regarding the time that should elapse between sessions, the information differs between men and women and between facial and body depilation. Let’s see the most common mistakes without losing sight of the fact that modifications can be made to adapt to the evolution of each person.

Laser Hair Removal for Women

Facial depilation in women: In the beginning, the sessions take place every five weeks, later usually at intervals of about six weeks.

Body hair removal for women: Sessions are held every eight to ten weeks. Although it may seem long, the treated area remains hair-free during this time.

Laser Hair Removal for Men

Male Facial Hair Removal: Initially, sessions are conducted every two weeks. In the final phase of treatment, on the other hand, they last longer than four weeks.

Body hair removal in men: The most normal thing is that the person will be called again in a period that varies between two and four months. This depends on the area being treated and the amount of hair you wish to remove.

In all of these cases, the next session is scheduled to coincide with the onset of the anagen or hair growth phase. At this point, you may be wondering: isn’t laser hair removal supposed to be permanent and prevent hair regrowth since it destroys the hair follicles? True, but remember that not all hair is at the same point in the life cycle when you start treating it. Therefore, several sessions are necessary.

For all these reasons, a complete treatment is usually between eight and twelve months. Once all the scheduled sessions are complete, the result will be permanent in 90% of cases. If hairs reappear, they are blonde and excellent. In any case, only a few maintenance sessions, usually annually, would be necessary.

If this happens in your case, don’t worry about an unexpected payment. The stop schedule gives you a flat rate for each zone, including the number of sessions you need and possible maintenance sessions. This way, you can only focus on what matters: showing a new image without hair.

Laser Hair Removal at Home, with Precautions

For individuals who use less power and, therefore, less efficient devices, the Agency insists on conditioning the marketing of these devices. It recommends more explicit instructions for use on the potential dangers. It proposes “tolerance studies before placing on the market as rigorous as those carried out for medical devices.”

Also, it requires much more detailed instructions for use, warnings, and contraindications with a complete practical guide:

“Shave beforehand and wash with traditional soap the area to be depilated, do not use anesthetic during a laser session, do not expose the same place more than once to the LASER beam during the same session, space sessions, etc.


Laser hair removal lasts when the laser destroys the hair follicle. If the hair gland is just damaged, the hair will eventually grow back. The time it takings for the hair to grow back depends on each person’s hair growth cycle.
