Laser hair removal is a promising and trending technology to remove unwanted body hair safely and help one achieve a smoother hair free skin. The laser technology safely removes excess or unwanted hair growth from the face and any part of the body.   

If you are seeking permanent laser hair reduction in Delhi, you are most likely to ask about the treatment duration and number of sessions needed to attain desired results. When told that multiple sessions are required in a specific time gap, your next question might be why there is a need for multiple sessions. All such questions are answered here in detail in this blog by laser experts. Take note that it’s crucial to dig deep into laser hair removal works and the treatment time to get the promised outcomes. For that, it’s crucial to understand the hair growth cycle. 

Understanding Natural Hair Growth Cycle and the Need for Multiple Laser Sessions

Each hair strand follows a three-stage growth cycle. The first stage is the anagen, where the hair strands actively grow. Next is the catagen, where the hair follicles start shrinking, and last is the telogen, where the hair falls. This three-stage cycle normally repeats itself every few weeks.

At a particular instance, each hair is not in the same stage of the hair growth cycle, and lasers only work on the hair follicles in the anagen stage. So, for laser hair removal to be a success, multiple sessions are required. With multiple sessions, lasers can target and damage the maximum number of unwanted hair follicles from which hair strands are growing.  

How Laser Hair Removal Works?

Lasers work to get rid of unwanted hair by using their light energy and then converting it into heat. This heat targets the melanin pigment present in the hair follicles/roots. Melanin is a colored pigment, present in the skin and hair, and responsible for their natural color. It is highly sensitive to laser light energy. So, when laser light hits the melanin of the targeted hair follicles, heat is produced, which gets absorbed by the melanin. The laser causes selective photothermolysis of the targeted hair follicles. This makes hair follicles incapable of producing new hair and leads to shedding of some of the existing targeted hair. The heat destruction and damage of the hair follicles only happen in case the follicles are actively growing hair.

Laser hair removal in Delhi by Dr. Rohit Batra at Dermaworld Skin and Laser Clinic can be done in almost all facial and body sites. For small areas, laser sessions last for a few minutes, but when treating large areas, each session can be an hour long. In general, lasers can quickly work on the targeted area, as in a single laser pulse, multiple hair follicles are focused. The clinic has the best machines for optimal unwanted hair removal.

How Many Laser Hair Removal Sessions Are Required to Complete the Treatment Process?

The number of times required for all or the maximum targeted hair to be successfully treated with laser is the number of laser hair removal sessions one would need. This is decided by the dermatologist after a thorough assessment of the patient and targeted area, and it is variable. The factors that influence the number of sittings needed include-

• The targeted area location and the skin tone: Small, easily accessible areas and areas with good contrast in skin and hair will require fewer laser hair removal sessions than would be needed in the opposite case.

• The hair color and texture: The dark, black hair, which is thick and coarse, shows a high response to the laser’s heat. As they can be easily removed, there will be a need for a few laser hair removal sessions. Extra appointments are required when hair is finer and softer or less dark.

• The type of laser: Different laser devices take different times to work. Alexandrite lasers are most rapid and highly effective for fine to medium hair and light to olive skin types.

• Age-related hormonal changes: Hair growth is influenced by hormones. Hormonal disturbances can cause hair to regrow even after laser treatment. This affects the number of laser hair removal sessions needed to achieve hair-free skin.

Typically, 6 to 12 sessions are required to complete the laser hair removal process.

What Should Be the Time Interval Between Laser Hair Removal Sessions?

In between laser hair removal sessions, there needs to be a gap of 4-6 weeks. This time frame needs to be maintained so that the thermal damage to the hair follicles covers all of the targeted area with every successive session.

After How Much Wait Do Results Become Apparent?

The results start appearing after 2-3 laser sessions. With further sessions, the hair growth gets delayed. After completion of the treatment course, there is almost zero hair growth for a minimum of 6 months, a year, or two, variable for each case. If minor hair regrowth occurs, occasional maintenance sessions may be required, as recommended by a dermatologist. Thereafter, there will be no need for shaving, waxing, plucking, or other hair removal methods.
