Laser hair removal works by heating your hair follicles to stop new growth. The procedure only reduces the number of unwanted hairs in a given area.
Results are apparent after your first treatment, but it will take several treatments to remove the hair permanently. Four to six sessions spaced about four weeks apart will give you about 70-80% of reduction in hair growth.
Laser hair removal generally lasts for at least two years. You will need, however, maintenance sessions to keep the area free from hair permanently.
Many clients swear by laser hair removal. Note, however, that using a laser feels like a rubber band flicking against your skin. Some patients do not tolerate this type of pain easily.
