Unwanted Hairs Treatment with Lasers

Laser Treatment for Unwanted Hairs


LASER is short form of a light having unique characteristics which makes it suitable for medical and surgical applications. These characteristics make laser so powerful that it can target a particular molecule in our body in a highly selective fashion without affecting surrounding structures. The property of certain lasers to target pigment and destroy structures carrying pigment like hair follicles forms the basic principle of laser mediated hair reduction. The hair follicles thus treated either become weak or get completely destroyed which adversely affects their growth and they tend to shed off.


Since all hairs do not carry a critical amount of pigment, hence all of them are not damaged to the same extent. Therefore, Laser hair treatment can at best decrease the number of hairs complete elimination of hairs is an ideal but unlikely outcome.


Principles of Laser Hair Reduction

·         Laser hair reduction is a safe procedure having been performed globally in millions of subjects

·         Each hair follows a particular life cycle which has several phases. The laser can target a hair in a particular phase. Since hairs are never in one phase, but are in different phases of growth. That explains why laser does not have a homogeneous impact on all hairs.

·         A light complexion of skin and darker hairs are most suitable for laser hair reduction.


Quick Facts

Until recent past, there was a paucity of options to help subjects get rid of unwanted hairs leading to psychological issues like frustration and disappointment with the use of expensive and inconvenient alternative procedures.

Laser hair removal can be carried out on any area of the body except over and around eyelids. The procedure is most commonly done for the face, legs, underarms, back, chest, upper limbs, shoulders, bikini line, and even groins.

Serial sittings at properly spaced intervals yield superior results. Areas with faster hair growth may be treated after an interval of four weeks while some other areas with slow hair growth might require sessions at intervals of 12-18 weeks. Some patients might be advised a maintenance schedule to prevent growing hairs reaching a significant level.
