The technique used in laser hair removal is known as selective photothermolysis. To safely achieve the intended consequences on a particular subject without harming the surrounding tissues, a precise wavelength will match pulse duration. When it comes to laser hair removal, the undesired hair is the aim, and the removal of hair is the outcome.

  • The pigments in the undesirable body hair will be the focus of the laser. The laser’s light energy will pass through the hair and into the hair follicle. It will then transform into heat energy and harm the hair follicle there. It’s critical that hair follicles are irreparably destroyed because they can renew and mend themselves over time.
  • In order to prevent the follicle from receiving any additional blood supply, the blood vessel supplying it must be cauterized. Then and only then can laser hair removal be successful.
  • Patients must wait six weeks between treatments for effective laser hair removal. Initially, to allow the skin to grow and mend. Even though laser hair removal is safe, the light energy employed nonetheless makes the skin more delicate and susceptible to outside aggressors after a treatment. As a result, it takes time to rebuild its strength.
  • The cycle of hair growth is another factor. The only time the hair and follicle contact, the energy can move from the former to the latter.
  • Therefore, only 18 to 20% of the hair in the targeted area may be removed with a single laser hair removal Waiting six weeks will allow hair that hasn’t grown yet or is in another stage of development to transition into the proper stage. The laser will then be able to find them and treat the area properly.
  • Because the laser can more effectively target the strongest source of pigments by contrasting body hair with skin, unfortunately, dark complexion and black hair provide very little contrast. The same is true for fair skin and blonde hair.
  • Each patient will require a different number of sessions for laser hair removal to be effective. In fact, some patients might only require six sessions to get rid of all the hair on their entire legs, whereas the same patient might require four additional sessions to be happy with the results of their bikini laser hair removal. More sessions are necessary to achieve satisfactory results in hormonal areas.
  • For instance, part of your hair follicles will already be destroyed if you waxed for ten years before switching to laser hair removal. Waxing does, in fact, slow down future hair growth. People with blonde hair, who are more difficult to target, could need more sessions.
