Laser hair removal is a cosmetic procedure that uses concentrated light to target hair follicles. The light energy is absorbed by the pigment in each follicle, which slows or reduces future hair growth. People choose this method for many reasons. Some want to spend less time shaving or waxing, while others prefer the convenience of a longer-lasting approach to unwanted hair. Here’s information on what to expect during your first laser hair removal session:
What a Treatment Is Like
Before your laser hair removal session begins, a technician will review the treatment area(s). You may be asked to wear protective eyewear, since the laser light is bright and can be uncomfortable to look at directly. Many clinics apply a cooling gel or use a device with a built-in cooling feature to protect the surface of your skin. During the session, the technician moves a handheld device across the treatment area.
Each pulse of light lasts only a fraction of a second, and you may feel a warm snapping sensation with each one. Smaller areas, such as the upper lip, can take just a few minutes. Larger areas, like the legs or back, may take closer to an hour. Afterward, the treated skin might look slightly red or feel warm, similar to a mild sunburn. This usually fades within a few hours to a day. Your technician may recommend applying a cool compress and avoiding direct sun exposure for a short period.
How Many Sessions Are Needed
Hair grows in cycles, and the laser works best on follicles that are in their active growth phase. Because not all follicles are active at the same time, most people need a series of sessions spaced several weeks apart. The exact number of sessions needed varies from person to person, and the amount depends on:
- An Individual’s Treatment Area
- An Individual’s Hair Color
- An Individual’s Hair Thickness
Many providers recommend a series of appointments, and they schedule these sessions weeks apart to match the natural hair growth cycle. After a session, you may notice what looks like new hair appearing or growing in the treated area. This is often the treated hair working its way out of the skin rather than fresh growth. Over the following days, this hair begins to shed on its own.
Who Can Get Laser Treatments
Laser hair removal works effectively when there is a clear contrast between skin tone and hair color, as the pigment in the hair absorbs the light. For this reason, this treatment doesn’t work well on blond, white, or very red hair, since they contain less pigment. Skin tone also plays a role in how a provider sets up the treatment. Modern devices can treat a wider range of skin tones, but a consultation helps determine the appropriate, personalized approach. During a cosmetic dermatology consultation, a trained provider will look at your hair and skin and explain whether laser treatment is a good match for your goals.
