Hair that grows on the face, upper lips hairs, forehead, ears, neck, abdomen, chin and under the chin and cheeks is called Hirsutism or excess hair growth. Removing these hairs is an unpleasant and difficult. There were various methods for removing excess hair for years. Face threading, shaving creams and powders, waxing, shaving machines, razors and tweezers, and chemical materials are some of these solutions to remove hairs. Due to the temporary and painful of these methods, we need a method that would eliminate the excess hair and difficult methods of removing them forever. In this regard, we can remove these hairs by using laser hair removal machine.
How laser hair removal works
If we want to explain the function of laser therapy briefly, it should be said that the light rays emitted from the laser device target skin pigments which called melanin.
The laser is applied to the skin and absorbed into the hair follicles, causing the melanin to heat up, resulting in the heating of the hair follicles, which eventually destroys the hair follicles.
Therefore, the goal of laser treatment is to damage the hair follicle to destroy that follicle and lose the ability of hair growth forever. However, it should be noted that in any case, the laser won`t remove all hairs in one session. (The reason why not all hair is lost in one session is related to the hair life cycle and growth stages).
The laser hair removing is depending on the skin type and different skin colors, a variety of lasers and their light sources can be used to remove excess body and face hair. Laser hair removal cause permanent and long-term hair loss and is a non-invasive method.
In the past, laser hair removal was used only for light-skinned people, but with the advancement of technology, today this method is also used for dark-skinned people and is safe for them.
In some cases, it may take several years to eliminate the excess hair. Cares must be taken after laser treatment. It is impossible to tell who needs a laser and how many sessions in order for the hair to be completely removed.
What is Alexandrite Laser Machine?
- 755 nm wavelength
The alexandrite laser is a type of laser that emits high-energy light from an alexandrite crystal. When light passes through the alexandrite crystal, a light beam with a wavelength of 755 nm is produced. This number determines how much laser light penetrates the skin. The color of the Alexandrite laser light is red.
The alexandrite laser can be placed in the Q-switch mode, which allows the laser to produce high-energy beams in short pulses. This is a feature which makes it effective for removing excess hair.
The Alexandrite laser is also used in the following cases:
- Aging spots treatment
- Spider veins treatment
- Congenital vascular spots treatment
The alexandrite laser has a higher speed than other models and the size of treated area is larger. Therefore, it is a good choice for treating large areas at high speed. This device has a tremendous depth of penetration and has made it one of the most effective and fastest methods available that requires fewer treatment sessions.
In addition, it has been proven to be more effective in removing thinner hair than other models, making it ideal choice for areas that do not have thick hair. The disadvantage of high speed is that it makes alexandrite laser more painful than ruby.
Despite its long wavelength, there is still a risk of skin pigmentation changes due to the high absorption of light by melanin in darker skin. So it is more responsive for fair skin.
Alexandrite is generally recognized as one of the safest and most effective laser methods for removing excess hair. Especially when you want to treat large areas of the body at high speed.
Benefits of Alexandrite Laser
Perhaps the best advantage is its high speed, which makes it possible to laser larger areas of the skin faster. This feature makes the Alexandrite laser one of the fastest hair removal methods.
Other models have a greater effect on thin hair and can also treat people with fair skin and freckles.
The Alex laser is considered to be the most effective type of laser for all skin and hair types, as it does not affect dark skin like other lasers. Like other lasers, the alexandrite laser is very effective for fair and very light skin and has also been shown to be very useful for removing very thin hair that many devices cannot remove.
The wavelength emitted by the alexandrite laser is easily absorbed by the melanin (pigment cells) in your hair, which causes the cells to heat up and die.
Note that for very dark skin, the Nd: YAG laser is the best option, because the high wavelength of this laser penetrates the hair follicles without affecting the skin.
With Alexandrite laser, the rate of hair loss after the recommended treatment sessions is about seventy percent. It usually takes between six and eight sessions for thinning hair and eight to twelve sessions for thicker hair.
Best candidates for laser hair removal
In general, laser treatment for people with fair skin and dark hair requires a few sessions, so note that if you plan to do both laser and tanning, do the laser first and then proceed to tan your skin. But in general, lasers are used to treat most people with different skin colors and even light brown hair. Naturally yellow, light red, or white hair has little pigment in its roots, so it cannot be completely removed with any laser.
Avoid laser hair removal if you:
- Age less than 17 years
- Having infectious diseases
- Congenital skin diseases
- Tonsil or thyroid Cancer
- Cardiovascular diseases
- Sunburned skin
- Taking Rakutan
Although the effect of laser on embryos has not been proven so far. It is also not recommended for pregnant women.
