What is a hair removal? Important points to know about laser
One of the most important things that affect the beauty of the skin of the face and body is the removal of unwanted hair, which can be done by laser hair removal. In addition to the unpleasant appearance of the hair, there is a possibility of the occurrence of purulent pimples and constant irritation of the skin.
Types of Hair Removal Methods: 1
Generally, there are two types of methods to remove unwanted hair:
1. Laser systems including alexandrite (low wavelength), diode and high wavelength laser devices
2. Non-laser systems (optical systems of xenon lamps) including E-LIGHT and IPL devices that work with the xenon flash lamp system and in addition to radio frequency light at the same time uses and for this reason it has a better effect on pale hair (golden, white).
How is laser hair removal?
Lasers are actually concentrated light beams that are adjusted to our desired wavelength for specific purposes and can have multiple effects in the desired area according to our needs. The root of each hair has a pigment called melanin, which is activated during hair growth and turns the entire body of the hair into a dark color (black, light brown, dark or blonde). Laser hair removal focuses on the melanin in the hair root and acts on that area and eventually leads to the destruction of the hair root. Therefore, the darker and thicker the person's hair, the better effect the laser will have on it. On the other hand, due to the presence of melanin in the skin itself, the lightness of the skin means that the laser does not affect the skin itself and does not lead to skin burns, so people with fair skin and thick and dark hair are the best candidates for laser hair removal. br>

اری Pre -laser council
Consultation with the supervisor and the person in charge of the laser department is mandatory before doing laser hair removal, and the laser work is done immediately after that. In the consultation session, the color of the skin and the type and thickness of the hair roots of the desired area are checked. Laser hair removal is not performed if symptoms of skin diseases such as eczema, herpes, hives, psoriasis, etc. are observed. Also, areas with sensitive skin and thin and fluffy hair should not be lasered.
Why is laser known the best way?
In fact, when it comes to removing facial and body hair, there are different ways to do it. You can try all these methods, but eventually the hair will grow back after a few days, usually accompanied by itching and sometimes sores. With its precision, the laser beam focuses on the hair pigment cells and distinguishes them from each other. Once the melanin in the hair is detected and targeted, the hair removal laser burns the entire hair shaft and root.
Types of laser wavelengths of excess hair
Laser hair removal devices basically have 3 wavelengths. 755 nm or alexandrite, 800 nm or diode and 1064 nm or ND-YAG
1. Alexandrite laser: suitable for light and normal skin
2. Diode laser system: suitable for normal, darkening skin, absorption of this wavelength in melanin is somewhat less than alexandrite lasers and more than Nd-YAG and IPLs.
3. ND-YAG lasers are safer and more effective for dark and tanned skin.
How do the rays grow?
Hair naturally has three stages of growth, rest and shedding, which are different for each person depending on various factors. The duration of hair growth is longer than the other two phases, but it is not the same in all people. During its growth cycle, your hair produces pigment that gives it color, and these pigments are what the laser targets. For this reason, the laser is more effective on follicles that are in the growth phase.
ماردی Hair is generally in these three stages: @
The cause of multiple laser sessions
The hairs that grow are not all in the same phase at the same time. In a laser session, some hair roots may be in the anagen phase and some in the catagen and telogen phases. For this reason, it is not possible to get a complete and definite result from laser hair removal with only one or two sessions, and the laser sessions must be completed regularly and at certain intervals until a certain time when all the roots are affected by the radiation.
مان The number of laser sessions
Usually the number of laser sessions is between 6 and 8 sessions. In some cases and specific areas, more sessions may be needed. For example, the bikini area shows the final result later than other areas of the body due to its continuous moisture. In order for the hair follicles to be fully exposed to the laser rays in each session, the hair roots must not be removed from the skin. Therefore, during the treatment, only use Gillette to correct the area that has been lasered.

What is the distance between laser hair removal sessions?
For most people, it is better to have four to eight weeks between each laser session, and generally 6 sessions are recommended for optimal results. But our advice is to schedule laser sessions according to the expert's opinion to get better results.
Various factors play a role in determining the intervals between laser sessions, including the rate of hair growth, the area treated by the laser, and skin color. In general, the ideal time between each laser session is 40 to 45 days.
Why wait between laser hair removal sessions?
There are several reasons why you should wait between laser hair removal sessions.
In order for the growth of unwanted hair to stop completely and for the laser to have a favorable result, several sessions should be performed at suitable time intervals for you. The interval between laser sessions is very important in the final result and should proceed according to the hair growth cycle.
Skin relaxation
The first reason is that you need to let the skin rest and regenerate after the laser. In fact, ultraviolet rays are very aggressive for the skin, and if the interval between laser sessions is short, it can lead to skin damage.
Follicole
The second reason is follicle regeneration. In fact, some follicles will be more resistant to the laser than others. Therefore, it may take more than one session to get rid of them permanently. When a hair follicle is not completely destroyed, it regenerates and can regrow new hair. Repeated targeting of resistant follicles does not give them enough time to regenerate.
🌸چرخه رشد مو🌸
The third reason is the hair growth cycle, which is different for each patient, each area of the body and also for each body hair. A strand of hair can be in the growth phase for up to 6 years. With this situation, how do we know what stage the hair is in? It is impossible to know this.
Why should the gap between laser hair removal?
40 to 45 days between laser sessions gives those hairs that were not in the growth or anagen phase a chance to enter this phase. However, because 20% of the hair anywhere on the body is in the appropriate phase, some of them are leaving this phase and others will enter this phase in subsequent sessions.

The numbing effect lasts for two or three hours.
