Laser hair removal is the best method to permanently eliminate unwanted hair from various regions of the body, such as armpits, legs, groin, intimate area and beard.

Diode laser hair removal eliminates more than 90% of hair, requiring about 4-6 sessions to completely eliminate hair from the treated area, and only 1 annual session, as a form of maintenance.

The price of each laser hair removal session varies between 150 and 300 reais, depending on the region where the clinic is located and the size of the area to be shaved.

How laser hair removal works

In this type of hair removal, the therapist will use a laser device that emits a wavelength that generates heat and that reaches the place where the hair grows, damaging it, the result is the elimination of the hair.

Before the 1st session, the therapist should properly clean the skin with alcohol to remove any traces of oil or moisturizing cream, and remove hair from the area to be treated with a razor or depilatory cream so that the laser can focus only in the hair bulb and not in the hair itself, in its most visible part. Then the laser treatment starts.

After each region is shaved, it is recommended to cool the skin with ice, spray or cold gel, but the latest equipment contains a tip that allows the site to be cooled right after each laser shot. At the end of each session, it is recommended to apply a soothing lotion to the treated skin.

About 15 days after the treatment, the hairs become loose and fall out, giving a false appearance of growth, but these are easily removed in the bath with a skin scrub.

Does laser hair removal hurt?

During the treatment, it is normal to feel a little pain and discomfort, as if there were some stings in the place. The thinner and more sensitive a person's skin, the greater the chance of experiencing pain during epilation. The areas where you feel the most pain are the ones with the most hair and where it is thicker, however it is in these regions that the result is better and faster, requiring fewer sessions.

Anesthetic ointment should not be applied before the procedure because it must be removed before the shots, and pain and intense burning sensation in the skin are important parameters to identify if there is a burn, with the need to better regulate the laser device.

Who can do laser hair removal

All he althy people, who do not have any chronic disease, and who are over 18 years old can have laser hair removal. Currently, even dark-skinned individuals can perform laser hair removal, using the most suitable equipment, which in this case is the 800 nm diode laser and the Nd:YAG 1 laser.064 nm. In light and dark skin, the alexandrite laser is the most effective, followed by the diode laser and finally the Nd:YAG.

Before performing laser hair removal, care should be taken such as:

  • Have the skin properly hydrated because that way the laser works better, so you should drink plenty of water and use moisturizing cream in the days before the treatment;
  • Do not perform hair removal that removes the hair from the root days before laser hair removal, because the laser must act exactly on the hair root;
  • No open wounds or bruises in the place where the epilation will be performed;
  • Naturally darker areas such as armpits, can be lightened with creams and ointments before the procedure for a better result;
  • Do not sunbathe for at least 1 month before and after performing the treatment, nor use self-tanning cream.

People who lighten their body hair can do laser hair removal, because the laser acts directly on the hair root, which never changes color.

How does the skin look after the session?

After the first laser hair removal session, it is normal for the exact location of the hair to be a little warmer and redder, which is indicative of the excellence of the treatment. This skin irritation disappears after a few hours.

Therefore, after a treatment session, it is necessary to take some care with the skin to prevent it from becoming stained and dark, such as soothing lotion and avoid exposing yourself to the sun, in addition to always using sunscreen in areas that can be naturally exposed to the sun such as face, lap, arms and hands.

How many sessions to do?

The number of sessions varies according to skin color, hair color, hair thickness and the size of the area to be shaved.

In general, people with fair skin and thick and dark hair need less sessions than people with dark skin and fine hair, for example. The ideal is to buy a package of 5 sessions and, if necessary, buy more sessions.

Sessions can be carried out with an interval of 30-45 days and when hair appears, shaving with a razor or depilatory creams is advised, if it is not possible to wait until the day of laser treatment. The use of a razor or depilatory creams is allowed because they can preserve the structure of the hair, not compromising the treatment.

Maintenance sessions are necessary because immature follicles may remain, which will still develop after treatment. As they did not have melanocytes, the laser cannot act on them. It is recommended that the 1st maintenance session be done after hair appears again, which varies from person to person, but is almost always after 8-12 months.
