Scroll down to read in detail. 

How does a Laser Hair Removal Work?

Hair contains a pigment known as melanin that gives them its colour. The higher the concentration of melanin, the darker the hair. The laser produces a high beam of light that penetrates the skin and targets the melanin in the hair follicle. This damages the root of the hair. As a result, the hair starts falling within a few days of the treatment. 

Technologies for Laser Hair Removal at Bliss Laser Skin Clinic

Dr. Shikha Agarwal, the best dermatologist in Ludhiana, uses two techniques for laser hair removal. These are: 

  • Diode Laser

This technique is good for all skin types because it doesn't target the melanin in the skin. Instead, it goes straight for the hair follicles. It works well for dark, coarse hair, which is why it is perfect for removing hair on the bikini lines. The wavelength of the Diode laser is between 800 and 810 nm. When the wavelength is longer, it can reach deeper into the skin. 

  • Alexandrite Laser

This technique is best for people with a light complexion and dark hair. It can easily cover a large area like the chest and back as the laser spots of alexandrite laser are quite bigger. 

How to Prepare Self for Laser Hair Removal? 

Here are some tips for one to follow to prepare themselves for a laser hair removal session: 

  • Avoid the sun before going for a laser treatment. As the laser targets melanin, treating tanned skin becomes difficult due to increased melanin content in the skin after sun exposure. 
  • Dr. Shikha Aggarwal advises not to bleach the skin before the session as bleach will make the body hair light in color. The treatment may not be as effective as on normal skin colour.  
  • It is also advised not to wax or pluck hair from the target area before the treatment. The laser light focuses on the root of the hair; Waxing and plucking take out the hair follicles, leaving nothing for the laser to aim at.
  • However, one can shave 24 hours before the treatment. This cuts open the hair follicles, making it easy for the laser to target them. 

Procedure of Laser Hair Removal

Here is what one can expect during the procedure of laser hair removal. 

  • As the patient goes for the treatment, they will be asked to wear a surgical gown. 
  • The patient and everyone in the room will wear protective eyeglasses to protect eyes from damage from the laser. 
  • After this, the target area will be cleaned to remove dirt and product residue.
  • Once properly cleaned, the laser technician will apply the numbing gel to the treatment area. This minimises any discomfort that one may experience during the process. 
  • After the numbing gel has done its job, the hair removal procedure starts. 
  • One session may take 1-2 hours, depending on the size of the treatment area. 
  • During the procedure, one may feel like hot rubber snaps on the skin, but this is temporary.

Benefits of Laser Hair Removal 

There are many benefits associated with laser hair removal treatment. These are: 

  • Laser hair removal is a hassle-free and painless (permanent) method of hair removal. 
  • It is cost-effective. Laser sessions are much less expensive than the cost spent on salon sessions, razors, epilators, hair removal creams, in the long run. 
  • The treatment does not involve any side effects. 
  • Compared to other methods, the laser is a long-term solution to the problem of body hair. 
  • It does not carry a risk of ingrown hair or strawberry skin (small bumps on the skin after hair removal)

  • This method can be used on any body part, even the smallest, like upper lips.
