While some take a whole lot of time, others are extremely painful to endure. But as time goes by, our hair removal methods have also gone through an upgrade. Ever wondered how does laser treatment for hair removal work? Introducing the laser hair removal procedure – a painless way to get rid of unwanted body hair. It’s hassle free, delays hair growth and keeps your skin soft and smooth for a long duration.

It’s time to say goodbye to your bi-monthly salon trips! Wondering how laser hair removal works and how long does it take for laser hair removal to work? Let us decode the science behind this revolutionary skin procedure.

What is Laser Hair Removal?

Laser Hair Reduction is the process of reducing hair growth by destroying the root of the hair follicles through a laser treatment. With the help of pulses of light designed to heat the hair follicle (till it dies), they are destroyed. This includes the use of specific wavelengths of light that targets pigment to keep the skin unharmed. 

How does laser treatment for hair removal work, you ask? It targets areas such as the chin, under arms, hands, legs, thighs and even the bikini area. After the procedure, hair starts falling off gradually and the new growth is significantly lesser and delayed. Hence, you remain hair free for a few months.

P.S. This is why laser hair reduction is known to be most effective on darker hair.

While options like threading, waxing, shaving, using epilators and electric treatments are available, they are extremely painful and do not offer permanent effective results. In fact, they can cause skin redness, irritation and some scars if not done by a professional. Also, they do not delay hair growth like laser hair reduction. In the next section, we detail out what to do before the procedure and answer the question “how long does it take for laser hair removal to work”.

A. Things to keep in mind before Laser Hair Removal?

Before you undergo a laser treatment for hair removal, it is important to understand how laser hair removal works and go through a few precautionary measures.

  • Your aesthetician will consult you on the basis of your skin type, needs and medical history to determine how long the process will take
  • Don’t pluck, shave* or use electrolysis for at least six weeks before the procedure
  • *Shave 24 hours before the procedure so that it’s easy for your aesthetician to detect the hair follicles and proceed to burn them.


B. What To Expect During The Laser Hair Removal?

After the initial consultation with your aesthetic surgeon, you can see for yourself how laser hair removal works. The session will last about a few minutes to an hour, depending on your target area.

  • You will be given protective eyewear to use during the laser hair removal procedure.
  • We will provide a complimentary underarm Laser Hair Reduction trial session to assess effectiveness and understand your level of comfort.
  • A cleanser/moisturiser is applied to the area which is to be shaved in order to prevent the experience of a burning sensation.
  • Once the hair is shaved and excess hair is dusted, the aesthetician marks out grids on the treatment area indicating sections that will receive the Laser Hair Removal treatment.
  • A cold gel is applied over the treatment area which enables the aesthetician to sweep the LHR handpiece across the area with ease and also prevents the laser from burning the skin.
  • After the area has been treated, the gel is removed and the area is wiped clean. Once the complete session is done, a moisturiser & sunblock is applied. And voila! That’s the magic of how laser hair removal works.

How Long Does it Take for Laser Hair Removal to Work?

How long does it take for the laser treatment for hair removal to start working? On average it takes some months for the full treatment, with sessions about 4 weeks apart (depending on the area being treated).  This is done because the treatment is effective only when the follicles are on their active growth cycle. With these growth phases in mind, the laser treatments are done on specific intervals.  Also, each part of the body has a different growth cycle so depending on the area of treatment, the time required to complete the treatment may vary.
