Laser hair removal is becoming more and more popular, and many of you may want to know more about laser hair removal, so let’s have a good introduction today.
Traditional hair removal methods are not ideal as there is no way to get rid of the root (destroy the hair follicle), instead, laser hair removal is a good option as it can achieve permanent hair removal.
What you may want to know about laser hair removal
1. How many times do I need laser hair removal? How long is the interval?
How long does it take for laser hair removal to achieve permanent hair removal? The answer depends on the hair growth in different areas.
It is important to know that the hair follicle structure and the growth cycle are different from one part to another and from one body type to another.
Hair growth is divided into anagen, catagen and telogen. During the anagen phase, the hair matricellular cells divide rapidly.
This is the period when the most melanin is present and is therefore extremely sensitive to laser light. In the catagen phase, the hair matrix degenerates and the hair papillae shrink. In the telogen phase, the hair follicle separates from the hair papilla and the hair is shed, the duration of the telogen phase varies depending on the area.
The relationship between the hair growth cycle and hair removal treatment.
① Because the laser has no obvious effect on the hair in the catagen and telogen phases, the laser can only work after these hairs have turned into the anagen phase, so laser hair removal needs several treatments to be effective.
② If the proportion of hair in the anagen phase is small, the number of treatments should be increased. Conversely, the number of treatments can be reduced.
③ As different parts of the hair have different growth cycles, there are differences in the interval between treatments. For example, hair on the head has a relatively short telogen period, so the interval can be as short as 1 month; hair on the trunk and extremities has a relatively long telogen period, so the interval between treatments should be about 1-2 months.
For areas where hair follicles grow quickly, such as armpit hair, about 5 sessions are sufficient, but what about areas where hair follicles grow slowly? Lip hair, for example, requires at least 10 sessions.
The length of the interval is also determined by the growth cycle. For longer cycles, the interval will definitely be longer, from 1.5 months to 2.5 months.
2. Does laser hair removal hurt?
Slightly painful, but the level of pain varies from person to person. The level of pain is mainly determined by the individual’s skin tone and the softness of the hair. Generally, the darker the skin tone and the thicker and harder the hair, the stronger the stinging sensation will be, but it is still within the tolerable range; people with fair skin colour and fine hair will feel less painful! For those who are sensitive to the pain season and need to apply a topical anaesthetic prior to treatment, please discuss this with your therapist first.
Ice laser hair removal can ensure that the temperature during the hair removal process is kept below 5℃, the comfort level will be much better and there is basically no pain during the hair removal process.
3. Can laser hair removal be permanent?
Yes, thirty years of clinical evidence show that laser hair removal is the only effective permanent hair removal. The laser penetrates the skin surface to reach the root of the hair follicle and directly destroys the hair follicle, thus causing the hair to lose its ability to regenerate. Since the process of heat absorption and necrosis of the hair follicle is irreversible, laser hair removal is able to achieve permanent hair removal. Laser hair removal is the safest, fastest and longest-lasting hair removal technology available.
4. What season is more suitable for Laser hair removal?
Laser hair removal is woundless, does not require a recovery period and can be performed at any time.
However, laser hair removal requires several sessions, so it is recommended that you choose autumn and winter, so that in summer you can enjoy wearing summer clothes and show your beauty freely.
5. Will laser hair removal affect perspiration?
As sweat glands and hair follicles are two separate tissues and the wavelengths of the laser are not the same, laser hair removal will not affect sweating.
According to the theory of selective photothermolysis, with the right choice of wavelength, pulse width and energy density, the laser can precisely destroy the hair follicle without causing damage to adjacent tissues. Studies have shown that the histological structure of the sweat glands is not damaged after laser hair removal and in clinically observed patients the function of the sweat glands is largely unaffected. The use of advanced laser hair removal instruments not only does not damage the skin, but also shrinks the pores, resulting in smoother and more delicate skin.
