The effectiveness of laser hair removal treatmentsdepends on the structure of the hair and the phase of the hair growth cycle. Each single hair consists of two important elements: the stem and root, hidden deep inside the skin, and surrounded by a hair follicle. Located at the base, living part of the hair structure is known as bulb, it contains the elements responsible for hair growth. Melanin, which plays a key role in the effectiveness of laser hair removal, is produced by cells called melanocytes, which form a part of the matrix.
Hair growth cycle can be divided into the following stages: growth (anagen), transitions (catagen) and resting (telogen). Laser hair removal works on the hair in its growth (anagen) phase by destroying the hair follicle together with the bulb and the matrix. The duration of the growth phase depending on the organism varies from 6 to 12 weeks and it is a key determinant to the effectiveness of laser hair removal. Simply speaking, the more hair in the growth stage, the more effective the treatment. During a single visit in the beauty salon, on average, we destroy about 20-30% of hair (depending on the number of hair in the growth phase). With each subsequent treatment session, the amount of remaining hair is reduced, and the full effects are visible after a series of treatment sessions is completed.
