Laser hair removal
There are a variety of methods for removing unwanted hair, such as cutting, shaving, waxing, and others, and each of them has its advantages, but it is not effective in permanently getting rid of hair growth. The use of laser hair removal is an innovative and convenient way to get rid of it permanently, and this is done by shining a focused beam of light on the hair follicles, the dye absorbs it and then the follicles die due to the high temperature.
How to use laser for hair removal?
The use of laser hair removal is characterized by its selectivity, as the light focused on the area on the natural hair dye that absorbs the light to reach the hair shaft, then increases its temperature to destroy the hair follicle, and thus stops hair growth again, and it is worth noting that the laser hair removal process needs several sessions; This is because hair has a life cycle that passes through several stages, namely: the resting stage, the transitional stage, and the growth stage. The hair in the dormant stage needs a period of time to appear on the surface and be affected by the laser, so the full treatment period needs between two to three months.
Session length
Laser pulses need fractions of a second to treat a large number of hairs at one time, and one laser session takes about an hour to treat large areas such as the back, and the area above the lips does not need more than a few minutes. And you can start noticing the results from the third session of the treatment. The required treatment period varies according to the region. The area above the lips, which is growing rapidly, needs four to eight weeks, and the back area needs a period of up to sixteen weeks.
Longevity of laser treatment
The use of laser hair removal is a permanent way to get rid of hair, except that part of the hair may return to growth again, but it is lighter and lighter than the previous one. It is recommended to do several separate sessions after the treatment so that the hair does not grow back at all, and if the hair continues to grow again, other solutions can be used to remove it, such as plucking. The speed of hair regrowth also depends on the nature of the hair going through the three stages of growth, which differ for each person; Some people have hair that grows faster than others, and hair that is in the dormant phase takes longer to grow. The chance of hair regrowth often depends on the nature of the hair and the skill of the therapist who offers the laser session.
Skin type and hair color
Skin color, hair color and nature play an important role in the effectiveness of using laser to remove hair permanently. White skin with black hair is more suitable for laser treatment; Where the pigment collects in the hair, which facilitates the laser targeting of the hair shaft and then moving towards the follicle to destroy it. People with dark skin or light hair need several sessions to get satisfactory results, and they may notice more hair growth after treatment than others. Some research was conducted in 2013, and the result was that using laser light with long wavelengths gives better results for people with dark skin, so for effective hair removal, the treating technician must know how to target the hair and the appropriate type of laser.
Tips for laser hair removal
It is important to choose the right clinic and the treating physician who is qualified and experienced in giving laser sessions, or that the treating person is properly trained and under the supervision of the responsible physician. Beware of spas, salons, and others that provide laser sessions by unqualified workers. When visiting the doctor for the first time, he will need some information, such as health history, history of skin disorders, and old hair removal methods; To understand the patient's condition and determine if laser sessions are appropriate for him, then develop a plan for sessions and costs.

Stay away from the sun: It is recommended to apply sunscreen with extensive protection daily, and you must adhere to the doctor’s advice regarding not exposure to the sun before treatment for a period of up to six weeks.
Skin bleaching: The doctor may request the use of a cream to whiten the skin if it has been tanned before, and the use of tanning creams and creams that do not contain sun protection should be avoided.

Shaving the area that will be subject to the laser session: It is recommended to cut or shave the hair a day before the laser session, in order to ensure that the skin is not damaged by the burning hair with the laser, because the presence of the cut hair makes the shining light penetrate into the hair shaft under the surface of the skin, affecting only the follicle.
Preparation for the laser session: Special glasses are worn to protect the eyes from laser rays, and a gel is used as a local anesthetic for the area to reduce tingling and discomfort.

The doctor's advice should be taken not to be exposed to the sun between sessions and to use a sunscreen.
