Traditional razors, liquid wax, hair removal creams, and others work superficially by cutting off the hair-growing edges. However, lasers target the hair follicles and restrict the hair growth cycle to stop hair growth in the targeted zones permanently. 

Are you worried about how many years you can cherish laser hair removal? This article takes you through how lasers work on hair-grown regions and damage the hair follicles with a sneak peek into the longevity of laser hair removal procedures and more.


1. What do you mean by laser hair removal?

Laser hair removal applies energy from intense light beams to remove unwanted body and facial hair. It is a non-invasive cosmetic procedure that can provide permanent results with repeated sessions. 

However, one can see a significant reduction in the amount and thickness of hair with the first session itself. Though hair can regrow back after laser treatment, the thickness and growth will be less minimal. 

And this Hair regrowth greatly depends on the targeted areas, fluctuating hormones, and how quickly the hair grows back.


2. How do lasers work in removing unwanted hair?

Lasers are high-beam intense light rays beneficial when used under permitted levels. Laser hair removal commonly treats hair growth regions of the body and face, including legs, arms, armpits, back, neck, upper lip, chin, shoulders, and bikini line. 

The basic principle of laser treatment is that the pigment cells or melanocytes of the skin absorb the laser and damage only the hair-producing follicles and not damage the skin. The risk of skin damage is lesser with light skin and dark hair colour. 

Most common question is how many sessions for laser hair removal. Lasers require 6 to 8 treatment sessions to show potential hair removal outcomes. However, the interval between the sessions depends on the area of the target. Hair tends to grow faster in areas like the upper lip, and one may need to repeat treatments in 4 to 8 weeks. But, in areas of slow growth like the back, a 12 to 16 weeks gap between sessions would be ideal.



3. Why does hair on certain regions of the body and face grow quickly?

After a laser hair removal hair session, hair may tend to grow back for many. And in some regions, they tend to grow faster.

This may be due to the fluctuations of hormones and androgen-initiated hair follicle reactivation, where androgens, such as dehydroepiandrosterone (DHEA) and testosterone, stimulate the regrowth of hair on the face and body. 

Sometimes, hair growth can occur in other areas of the legs, arms, stomach, bikini line, and underarms, causing paradoxical hypertrichosis. 

However, lasers can work on these hair growth factors. Hair regrowth with laser treatment tends to be finer and more sparse. And with repeated sessions, the treatment effects get to be eventually visible. Hair regrowth on the body and face differ post laser. 

Hair regrowth on the body

With due course of treatment, you may find hair regrowing, but as the treatment completes, hair regrowth will eventually come down and will not be seen for many years. Laser hair treatment on the body shows long-lasting results; even if hair grows back, it will be fine and less dense.   

Hair regrowth on the face

Laser hair removal on the face may not show typical permanent results like the body. Some have reported hair regrowth on the face after 10 years of laser treatment. And so people opting for facial hair removal treatment through lasers will need to go for an annual touch-up treatment to keep away unwanted hair growths.  


4. Will repeated laser therapy sessions eventually decrease hair growth?

Laser treatments usually come with a package of sessions. Some may require more sessions than others, while some may need only minimal touch-ups for hassle-free, no-hair skin.  

With repeated laser hair removals, the hair regrowth decreases in thickness and amount of strands. And depending on the area of treatment, skin, and hair type, within 12 sessions, one may have long-lasting, permanent hair removal results.
