People remove hair and body hair for multiple reasons including health, hygiene, medical conditions, aesthetics, etc. Over the years, several hair removal methods have emerged, starting from shaving to laser hair removal.
In this blog, we shall explore how hair removal works and if it is permanent.
How laser hair removal works?
Our skin layers, namely the dermis and epidermis, have a tubular, sac-like structure called hair follicles. This is where the hair grows from. This is present in different parts of our body, such as the head, face, chest, underarms, bikini lines, arms, legs, face, chest, legs, and back, etc.
Removing the hair using a laser beam is an extremely efficient method. This is because this is an advanced laser hair removal procedure done in a targeted area with precision. This is a long-term solution for hair growth reduction. Not only that, it also helps to even out skin tone.

Target area preparation
Depending on the target area, the skin type, and requirements, a topical numbing cream may be applied before starting the procedure. This may or may not be needed and it has to be consulted between the patient and a certified dermatologist or esthetician.
-
Spot testing
Before starting the procedure, a spot test is carried out to check the following:
- Laser beam type
- Skin hair color
- Skin type
- Skin suitability
- Melanin (skin pigment) ratio and distribution
These are done to ensure the right amount of laser beam is used at the target area, causing minimal discomfort to the patient. This is discussed beforehand so that the patient is prepared for it.

Laser work
Using a concentrated light beam, hair follicles are precisely targeted and damaged. To effectively remove the hair, the hair follicle must be damaged. Naturally, our hair falls due to the hair follicles being loosened or damaged. Therefore, the laser generates a suitable amount of heat to do this.
The melanin or skin pigment in the hair follicles absorbs the heat energy from the laser, breaking it down. This decreases their ability to grow new hair.
Also, the procedure can be done on all skin types since it helps to even out the skin tone. As follicles may be slightly darker than the skin tone, the laser will break it down, making the hair color lighter, and blend with the skin tone- even if some hair remains after the treatment.
So, is it permanent?
Every skin treatment procedure takes a few to several sessions. However, for laser hair removal, the sessions are usually a few and take less procedural time. Given the number of sessions, there will be a great reduction in the overall hair growth, over time.
The hair will have a lighter appearance, making it less noticeable over time. As hair growth is a normal natural phenomenon, there may be some hair growth after a long time in the targeted area. As laser hair removal is convenient, it can be done again if required.
Conclusion
laser hair removal is an easy process that is less invasive than other skin treatments or procedures. It is relatively convenient and easy to do since it requires only a few sessions to get the desired results. For smooth, buttery skin, laser hair removal is a great option. The best practice is to understand the process and know which procedure is the most suitable for your skin. Finally, consult with a medically approved dermatologist or esthetician.
