Laser hair removal is a popular method today to tackle unwanted hair growth in an efficient and long-lasting way. But how exactly does this technique work, and what can you expect if you opt for laser treatment? In this comprehensive blog, we'll take you through the world of laser hair removal, from the science behind the technique to practical tips for your first treatment.

What is laser hair removal?

Laser hair removal is a cosmetic treatment in which a concentrated beam of light (laser) is used to destroy hair follicles. The laser emits light that is absorbed by the pigment (melanin) in the hair. This energy is converted into heat, which damages the hair follicles and hinders future hair growth. The result? Less visible hair growth and silky smooth skin.

How does the process work?

  1. Melanin absorbs the light: The pigment in the hair acts as a target for the laser.
  2. Hair follicles are destroyed: The heat generated by the laser damages the hair follicles.
  3. Growth is reduced: The damaged hair follicle can no longer produce new hair.

It is important to understand that laser hair removal is more effective on dark hair with high melanin content. For lighter hair types, other techniques may be better suited.

What can you expect during your first treatment?

Many people find the first step toward laser hair removal exciting. Here's what to expect:

Preparation

  • Shaving: Shave the area to be treated 24 hours before your appointment. The hair should be short so the laser can focus on the hair follicle and not the hair above the skin.

  • Avoid sun exposure: Don't expose your skin to the sun for two weeks before treatment and avoid sunscreen products containing self-tanner.

  • No waxing or tweezing: Avoid these methods at least four weeks before treatment. The laser needs the hair follicle to be effective.

During treatment

Your skin is cleansed and prepared with a cooling gel. Then the laser is moved over the treated area. Many people describe the sensation as a warm tingle or the snapping of a rubber band against the skin. Thanks to modern laser technologies, such as the GentleMax Pro, the treatment is usually comfortable and quick.

After treatment

  • Redness and swelling: The treated area may become slightly red, similar to a light sunburn.

  • Avoid heat: Avoid hot showers, saunas and intense exercise for 24 hours after treatment.

  • Use sunscreen: Protect your skin with a sunscreen of at least SPF 30.

How many treatments do you need?

Laser hair removal requires several sessions to be effective, usually between 6 and 8 treatments. This is because hair grows in different stages:

  • Anagenic phase (active growth phase): The laser is most effective during this phase.

  • Catagen phase (transitional phase): The hair follicle retracts and is less sensitive to the laser.

  • Telogen phase (resting phase): The hair falls out and the laser has no effect.

Because not all hairs are in the anagen phase at the same time, multiple treatments are needed to effectively treat all hairs.

Benefits of laser hair removal

  1. Long-lasting results: Unlike shaving or waxing, laser hair removal offers long-term reduction in hair growth.

  2. Fast and effective: Large areas, such as legs or back, can be treated in a short time.

  3. Little discomfort: Modern technologies make the treatment virtually painless.

Possible side effects and how to avoid them

Although laser hair removal is generally safe, side effects can occur:

  • Redness and irritation: This usually disappears within a few hours.

  • Hyperpigmentation or hypopigmentation: This is rare and can be prevented by avoiding sun exposure.

  • Ingrown hairs: Laser hair removal often helps reduce ingrown hairs, but can also cause temporary irritation in some cases.

Is laser hair removal right for you?

Laser hair removal is suitable for most skin and hair types, but effectiveness may vary depending on your unique characteristics:

  • Dark hair and light skin: This is the ideal combination for laser hair removal.

  • Light hair or dark skin: Modern laser devices, such as the GentleMax Pro, can also be effective for these groups, but may require more sessions.
