Permanent body hair removal

Thick hair was always desirable but the desirability of body hair is determined by its location. Unwanted body hair has always been a great aesthetic issue which was given a medical, social and cultural meaning. From ancient times man has waged wars with unwanted hair which he tried to remove unsuccessfully. The most famous was Cleopatra's preparation based on lemon and honey. After her many different methods appeared: plucking, wax, shaving, enzyme epilation...   
These methods are unpleasant and give temporary results. Most methods have various unpleasant side effects such as pigmentation development, most commonly on the upper lip and ingrowth of hair which causes scars.

Everything about hair

A hair develops from special stem cells which are located in the hair root. Just by destroying stem cells in the hair root we can prevent their growth. There are two hair types: vellus and terminal hair. Vellus is the thin, gentle light blond hair with which we are born. Out total number of hair is determined by birth and cannot be amplified. Hair which grows after a removal treatment is immature hair which matures in time (this is not new hair). Shaving does not increase the total number of hair but strengthens the existing root and speeds up their maturing process.
During time and  due to hormones and other factors a vellus hair matures into a terminal hair which is darker and thicker. Hair color depends on the quantity of pigment melanin, which is the main target of laser hair removal or an IPL treatment. There are two types of pigment which give hair its color: eumelanin and pheomelanin. If there is more pheomelanin, as is with light blond and red hair, the removal result is poor because that pigment type absorbs the laser ray poorly. If there is more eumelanin, the result will be excellent because that type of pigment absorbs the laser energy very well.
The amount of one's hair depends on numerous factors: race, genetics, age, climate, skin color... For Mediterranean climate, thicker black hair is usual, while in more northern parts hair is lighter and gentler. In many families the amount of hair is plentiful, especially with women of darker complexion, and the cause are not hormonal disorders.
