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.
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.
Diode laser is one of the newest lasers on the market. Like the alexandrite laser, it has a high penetration depth into the hair follicle, which protects the skin from radiation and thus safer treatment. This feature makes the diode laser safe for dark skin.
Diode is designed for light to medium skin and has the best effect on dark and thick hair. Its ability to cover large areas makes it a great choice for the waist and bikini area. The novelty of this method means that not enough research has been done on its long-term results. The long-term results reported show a 70% reduction in hair after eighteen months.
In terms of side effects, even with greater penetration depth, hyperpigmentation and scarring are still possible. In most cases, the side effects are temporary.
The benefits of diode are its effectiveness in treating dark and tanned skin as well as coarse and thick hair. Although alexandrite laser treatment is possible for light skin and ND-YAG for dark skin, it has been scientifically proven that the diode laser is the only model that can effectively treat various skin types with one device.
Its longer wavelength reduces the risk of skin damage. It has a shorter treatment duration and faster recovery. It has a greater effect on coarse hair than other.
High speed treatment: Hundreds of extra hairs are targeted at each beam of light emitted by a laser hair removal device. Removing facial hair follicles takes only 10 minutes, and this time for larger areas is half an hour, which is definitely a faster way to get rid of excess hair.
Fewer treatment sessions: Because the Diode laser hair removal device targets a large number of hair follicles each time, the number of sessions required to complete the treatment is greatly reduced. The number of sessions required depends on the color of the excess hair and the skin color of the area.
Painless treatment: Diode laser hair removal is a relatively painless, and only in some people, if the Diode laser light is too focused on high-sensitivity areas, it may feel a slight burning sensation.
Permanent Hair Removal: Diode hair removal is a relatively permanent method of removing facial, body and genital hair.
Effective for all skin types in both men and women: Diode laser for excess hair can be used for all skin types, especially dark skins, it can also be used for both men and women.
Most people need an average of 6-10 sessions to remove the main part of their hair. This treatment works by targeting the hair during its active growth phase, and because the hair has grown at different stages of its growth cycle, it will take several sessions to remove all the follicles in the area. The outcome of treatment depends on the area being treated, gender, age and hormone levels.
In general, laser treatment for people with fair skin and dark hair requires a fewer session, so note that if you plan to do both laser and tanning, first do the laser and then do the tanning. But in general, lasers are used to treat most people with different skin colors and even light brown hair. Hair that is naturally yellow, bright red, or white has little pigment in its roots, so it cannot be completely removed with any laser.
Although the effect of laser on embryos has not been proven so far. Laser use is also not recommended for pregnant women.
