No one likes shaving. Well, beyond your 15-year-old who is shaving for the first time, no one likes shaving. That is true regardless of sex, age, or any other criteria. The prospect of dragging an incredibly sharp piece of metal across your skin week after week for your entire life is just a drag, literally and every other way!

How does the laser get rid of the hair?
Some people incorrectly assume that the laser energy somehow cuts the hair, but if that were true, the hair would still return. What’s key is to damage the body’s ability to grow the hair in the treatment area. This involves two keys — laser energy and the hair follicle. For permanent hair removal, the hair follicle’s bulb, bulge, and papilla must be destroyed.
The vehicle is laser energy. We calibrate the laser to the wavelength where the melanin in the hair will absorb the laser energy. Different lasers and different calibrations are used to effectively address different hair colors. Melanin is responsible for that color. When the laser energy is delivered onto the target area, the melanin absorbs the energy. It converts to heat and travels down the hair shaft into the follicle. When it reaches the follicle the heat damages the follicle so that it cannot produce hair. Sometimes, if the follicle isn’t fully disabled, hair growth function can return in a few months.
Timing is important
That’s why the timing of laser hair removal is important. People wonder why you can’t zap the hair once and have it gone forever, but the timing has to be right. Only actively growing hair responds well to laser treatments because the hair has the most melanin in that phase. But in addition to the anagen (active growth) phase, there is telogen (no growth), and cathagen (hair ejection) phases. The human body has around five million hair follicles; men have a few hundred thousand more than women. All of those hairs are in different phases at different times. Plus, different areas of the body have more hairs in anagen phases than others, because hair growth is more important in those areas.
That’s why it takes multiple laser hair removal sessions to get the maximum hair reduction. Each client is unique, but in general, you can expect to need between four and eight treatments, spaced six to 12 weeks apart. These numbers vary by the body location of the unwanted hair. Also, some areas grow hair more densely. Compare, for instance, a man’s beard area with chest hair. Big difference in hair density.
