What is unwanted hair?
People who experience particularly excessive, unwanted hair usually do so due to hormonal imbalances. Darker, thicker hair is usually caused by higher than normal quantities of the hormone testosterone. This occurs particularly in women who have higher levels of testosterone, a hormone which is naturally higher in males. This can happen naturally or it can be caused by medications which affect your hormones.
Polycystic ovarian syndrome can also have an impact on amounts of unwanted hair. Benign cysts which appear on the ovaries can impact the production of hormones. This can lead to many symptoms including weight changes and more hair than usual. Any disorders which affect the adrenal glands, which control hormone production, can also impact the amount of hair on the face and body.
To reduce the amount of unwanted hair you can consult a GP if the medication you are on is affecting your hormones in this way. Shaving and waxing are short term options to reduce the amount of hair.
To achieve long lasting or permanent hair removal, laser treatments are used, it is necessary to destroy the hair follicle from which individual hairs grow. Controlled pulses of light penetrate the epidermis and are absorbed by melanin in the hair contained in the follicle.
Melanin converts the light energy into heat. This heat is transferred to the hair follicle, which is destroyed, making it unable to produce a new hair. Hair in the resting (telogen stage) are treated later. The treatment is only effective on growing hairs as these are still attached to the follicle.
