How Many Sessions Are Needed For Laser Hair Removal

Up until now, laser hair removal is still the preferred method for removing unwanted hair from one’s body. This is due to their efficiency, precision, minimum risk of ingrown hair, convenience, and long-lasting result.

To get the best long-lasting results, however, the treatment needs to be done in multiple sessions. It is not an instant treatment where you can enjoy the result from just having the treatment once.

But how many sessions is exactly needed to get the desired result? Well, each person can have a varied amount of sessions they will need. In this article, we’re going to tell you the general amount you will need, and what affects those numbers.

Amount of Sessions Needed for Laser Hair Removal

Generally, it is recommended to undergo a series of treatments, typically spaced about 4-6 weeks apart, in order to achieve the desired results. Treatment intervals also vary depending on the specific laser being used and the area being treated. Some lasers may require treatments every 4 to 6 weeks, while others may be spaced out every 8 to 12 weeks.

Most people will need between 6 and 12 laser hair removal sessions to achieve satisfactory results. However, some may need more or fewer sessions depending on their individual circumstances. It is important to follow the treatment plan recommended by your provider and to be patient, as it can take several weeks or months to see the full effects of laser hair removal.

Factors Affecting How Many Laser Hair Removal Sessions You Will Need

The number of sessions needed for laser hair removal can vary depending on a number of factors, including the type of laser being used, the thickness and density of the hair being treated, the skin tone, and the area being treated. 

1. Laser type

There are several types of lasers that can be used for laser hair removal. Some of the most commonly used lasers include Alexandrite lasers, Diode lasers, Nd: YAG laser, and IPL (Intense Pulsed Light). Some lasers require more sessions, whereas some require less.

For example, compared to other types of laser hair removal treatments, the Diode laser treatment often requires less sessions for completion. In contrast, Alexandrite treatment may take more sessions to achieve. This difference is due to different wavelengths of each laser type.

2. Hair thickness

A very thick hair can take longer to be permanently destroyed. Thicker hair requires more effort for the laser to completely abolish it. However, thinner hairs can also present a challenge because they may not be a robust enough target for the laser to find and remove the hair.

3. Hair density

Each laser lens has different diameters which indicate the spot size of the energy that will be delivered. That is why when a patient has dense hair surrounding a large area, such as the back, the laser will be able to eliminate them faster, compared to fewer hair on the chin with multiple separate spots.

4. Skin tone

Generally, laser hair removal is most effective on people with light skin and dark hair. If you have darker skin or lighter hair, you may need more sessions to achieve the same results.

5. Area being treated

The area being treated can also affect the number of sessions needed. Larger areas, such as the legs or back, may require more sessions than smaller areas, such as the upper lip or chin.

It is also important to note that laser hair removal is semi-permanent, and most people will need to undergo maintenance treatments in the future to keep the treated area hair-free. Due to that reason, it is best to choose a treatment centre that can accommodate your needs the best.
