How to use the laser
The laser is used to removing hair by highlighting the area with the natural hair dye that absorbs light to reach the hair shaft, then its temperature increases to destroy the hair follicle, and thus stops hair growth again, and the laser hair removal process needs several sessions; This is because hair has a life cycle that passes through several stages, namely: the stillness phase, the transition phase, and the growth phase.
Hair in the dormant stage needs a period to appear on the surface and is affected by the laser, so the complete treatment period needs between two to three months.
The length of the sessions
Laser pulses need fractions of a second to treat a lot of hair at one time, and one laser session takes about an hour to treat large areas such as the back, while the area above the lips does not need more than a few minutes.
Results can start from the third session of treatment.
The required treatment period varies according to the region, so the area above the lips that grows rapidly needs four to eight weeks, and the back area needs a period of up to sixteen weeks.
The durability of laser treatment
Laser hair removal is known as a permanent and fast method, but a part of the hair may grow back again, in a lighter and lighter form than the previous one, so even if the laser fails to completely eliminate the hair follicle, it weakens it greatly, and to get rid of it and prevent it from growing again, it is recommended to do several separate sessions.
After the treatment, so that the hair does not grow back at all, and if the hair continues to grow again, other solutions can be resorted to removing it, such as plucking. The speed of hair regrowth also depends on the nature of the hair’s passing through the three growth stages, which are different for each person. There are people whose hair grows faster than others, and the hair in the dormant phase takes longer to grow.
Skin type and hair color
Skin color, hair color, and nature play an important role in the effective use of laser for permanent hair removal so that white skin with black hair is more suitable for laser treatment; Where the pigment collects in the hair, which makes it easier to target the laser to the hair shaft and then move towards the follicle to destroy it. Unlike dark skin or light hair, they need several sessions to get satisfactory results, and hair may grow after treatment more than others. Some research was conducted in 2013, which concluded that using laser light with long wavelengths gives better results for people with darker skin tones.
