How Does Laser Hair Removal Work? 

The permanent reduction of hair is rapidly becoming one of—if not the most—popular and sought-after cosmetic treatments all over the world. With the advancements in light-based procedures and equipment, such as Alexandrite and Nd YAG laser wavelengths, rapid rates of repetition, and synchronized and adjustable proportions, you no longer need to go through bothersome and tedious options for hair removal like waxing, tweezing, and shaving that often require regular maintenance.

These days, most patients looking to get rid of unwanted hair can opt for more permanent methods like laser removal. This treatment option uses concentrated light beams to precisely eliminate follicles of hair to prevent their future growth. With that in mind, we’ll talk about the process behind the procedure in this article.  

Procedure overview for laser treatments

While the light-based technologies utilized for hair removal can vary, the treatments are generally similar for most procedures. During the session, bright flashes of light will be emitted on the targeted areas, with the light penetrating your skin and targeting the selected melanin in your hair follicles. The light energy is absorbed by the pigment, effectively eliminating the hair. It’s possible for multiple hairs to be treated at the same time, depending on how big the handpiece used is. 

Often, it takes multiple sessions to ensure that the hair follicles are accurately targeted during the growth stage. It’s not uncommon for most patients to get four to six treatment sessions to achieve the desired, long-lasting, and permanent results. It’s also worth noting that while laser treatments are permanent, it doesn’t necessarily mean that they don’t require touch-ups. In reality, it should be expected, especially in the beginning.

Most patients should start to see results upon the completion of their first session—hairs will begin to grow much weaker and finer than they initially were, and the skin will start to feel smoother. The results will gradually become more and more impressive and noticeable with every succeeding session until the follicles are all completely eliminated, permanently stopping their growth.   

Some expectations for laser removal 

Usually, the hair on the areas to be treated is trimmed to right above the surface of the skin. Topical numbing solutions are applied around half an hour before the procedure to keep any discomfort at a minimum. Also, the laser will need to be adjusted and calibrated to your skin type and the location and thickness of the hair to ensure that the hair is removed successfully with minimal or no adverse effects.

Depending on what light source or laser is used, the technician and you may need to wear protective eyewear to prevent any damage to the eyes. It’s also necessary to use a special device for cooling or a cold gel to keep the skin’s outer layer protected. 


Laser removal may sound like a complicated affair—and in reality, it can be. However, the process is much simpler than you might think. Ultimately, the results will depend on the laser hair removal machine suppliers and how much preparation is done beforehand. So make sure to choose your specialists carefully and let them know what you’re after.
