During a laser session, the laser emits light energy to follicular structures thereby injuring the hair follicle and reducing the ability for it to produce a hair. The technical objective is to destroy the hair follicle by heating it to a high enough temperature without damaging the surrounding tissue. Since not all of the hair follicles produce hair at the same time, multiple treatments are required to effectively treat all the growth cycles. Factors such as thickness, colour of the hair, hormones, laser energy used, clinical standards and experience of the technician may all affect the number of treatments required.

The answer lies in the worry-free time spent without stubble or regrowth. When treated with Laser, hair-free skin can last as long as 6 weeks or longer. Every subsequent treatment permanently erases follicles that are in the growth phase. Regrowth becomes less dense after each treatment.

The general rule of thumb is 8 treatments. Hormones, skin and hair colour are all variables. Most follicles on the face and body remain dormant until triggered by hormones. This is the most evident during puberty or post menopause. The key is to have hair permanently removed before they lose their colour, in which case the laser cannot treat them. Other treatment options such as waxing or electrolysis are best used for grey or white hair.

Both yes, and no. Hormonal changes that stimulate previously dormant follicles may require annual or semi-annual treatments if the area was previously, fully treated. Think of it as a permanent reduction, often times up to 90% reduced.
