Remove hair permanently

Excessive hair is one of the most annoying problems for many women and men. Despite the use of old and inherited traditional methods such as wax, razor or hair removal preparations, they are all temporary means whose results do not last long, hair quickly grows again, requiring repeated use regularly to obtain satisfactory results, and each has some side effects that harm Skin health over time.

Types of laser hair removal

Many types of lasers are used for hair removal, which is numerous, and it is essential to start the laser hair removal process by choosing the right type of laser. Before application, expert physicians must decide on the appropriate laser method for the person by evaluating the skin and hair structure. With this evaluation, the expected success rate of hair removal increases and the likelihood of side effects is reduced.

Diode laser for hair removal

"Diode laser" is a treatment administration aimed at reducing unwanted hair. Because the diode laser wavelength is longer than other laser methods, effective results that vary according to the treatment time are obtained even on darker skin. The diode laser has a wavelength of 810 nm. This wavelength goes deeper into the skin than the Alexandrite laser. More effective for deep penetration into the skin and in areas with deep hair. The diode laser can be applied comfortably even on dark skin, as it has a long wavelength.

Features of Diode laser hair removal machine
  • more typical in men, as it is used to get rid of back or chest hair.
  • A suitable option for people with dark skin.
  • Ideal for getting rid of coarse and dark hair.
  • The laser wavelength ranges between 800 and 810 nanometers.
  • It penetrates deeply into the hair follicles.

Nd-YAG laser

The long-pulse laser can be used safely on all skin types, including dark skin but is less effective with delicate or light hair than other lasers.

Features of Yag laser hair removal machine
  • The latest types of cosmetic lasers.
  • Does not target melanin in the skin; it is safe for people with dark skin.
  • It can be used for laser skin peeling.
  • It is also used to remove tattoos from the skin.

Alexandrite Laser Hair Removal

Due to its technical features, the Alexandrite laser is a practical and effective method that can only be used on open skin types. Removing hair from the surface immediately after treatment increases satisfaction after application. Applying this laser to dark-skinned people increases the chance of side effects. Using the Alexandrite laser on areas such as the face and neck may increase thinning hair. It is not recommended for use in these areas, even if the skin tone is light. Alexandrite laser is well held by melanin. Therefore, it can only be used on open skin types. This laser system works well for adequately selected people. However, dangerous areas such as the face can cause hair to grow rather than reduce hair. The back, shoulder and arm areas are among the areas where the effectiveness of this laser is low. It is an advanced regimen for very dark skin types. This laser is very painful and has space restrictions compared to the other two. The laser is rarely used in very carefully chosen situations.

Features of Alexandrite laser for hair removal
  • It is the most common device for laser hair removal.
  • An ideal option to get rid of hair on large body areas.
  • The fastest hair removal device available.
  • Its wavelength is 755 nanometers.
  • A suitable option for people with white skin.
  • It can get rid of freckles.

In addition, there are two devices with other features, such as the ruby laser device and the pulsed light device.

Features of Intense pulsed light devices

  • It does not use an accurate laser but rather an intense pulsed light similar to it.
  • The wavelength used can be controlled.
  • Suitable for removing hair from large areas within a short period.
  • Less effective than the YAG laser.

Ruby laser features:

  • It is the oldest laser device.
  • Less painful than others.
  • Ideal for fine hair and hair.
  • Its wavelength is 694 nm.
  • It needs more sessions than others to achieve the same results.
  • may be harmless for people with dark skin.
  • Not effective for light or gray hair.
  • An ideal option to get rid of hair in small areas of the body.

Cold laser hair removal

Cold laser hair removal destroys the roots of the hair follicles. During the treatment, light flashes are scattered over the skin and absorbed by the melanin in the hair follicles. The temperature of the laser energy increases and damages the hair follicles, which leads to the successful destruction of the cells that stimulate regrowth. It is important to note that hair grows in a cycle and that hair removal is only effective during the active growth phase. Each hair goes through three stages of growth:

  1. Growth stage
  2. Regression stage
  3. The resting phase.

The growth phase is the process in which your hair continues to grow actively. The regression phase, also known as the transition phase, is when the hair follicle shrinks and separates from the papilla, a structure at the follicle's base. The telogen phase, also known as the resting phase, is the phase in which old hair is released and shed. When the old hair falls out, the hair follicle reverts to the papilla and re-enters the growth phase, and the cycle repeats. Each hair on your body can go through a different phase of its growth cycle at any time. Therefore, several cold laser hair removal treatments are required to target multiple hair follicles during their growth phase to target hair in growth phase.

How is laser hair removal applied?

The laser beams produced in the laser device are applied to the skin using a hand tool. A 15 mm diameter area is scanned using one shot at a time. People who perform laser hair removal should wear safety glasses during the procedure. The rays applied to the skin are held by a pigment substance called melanin, which is in the structure of the hair and gives it a black color. The trapped light energy is converted into heat energy in the hair. The heat transmitted to the hair root destroys the hair root within milliseconds. At this moment, there is a slight needle-like feeling, and swelling and redness of the hair follicles are noted. These symptoms indicate that the hair is affected. Thanks to the contact air and cooling provided through the device, the skin is protected, and pain and side effects are reduced. It is noted that redness and edema pass even during cooling.

Results

Hair does not fall out immediately but will fall out over days to weeks. This may look like continuous hair growth. Repeated treatments are usually necessary because hair growth and loss occur naturally in its natural growth cycle, and laser treatment works best with hair follicles in the new growth phase. Results can vary widely and are difficult to predict. Most people undergo hair removal through a process that lasts for several months and may last for years. However, laser hair removal does not guarantee permanent hair removal. When the hair grows back, it is usually more delicate and lighter in color.
