The root of each hair contains a pigment called melanin, which is gradually activated during hair growth, coloring all hair in black, brown, blonde and other colors. The mechanism of action of the laser is based on the bombardment and destruction of the pigment or melanin in the hair roots.
Laser hair removal is one of the most important hair removal methods. This method is non-invasive and is based on acting on the hair follicles at the hair roots without causing skin damage such as redness, itching and pimples. Due to laser radiation, the hair follicles are heated and the hair roots are destroyed. Hair grows in different time cycles. That is why laser hair removal should be carried out in several stages and at different intervals.
What you should know about laser hair removal is that this method causes hair loss by affecting the melanin in the hair follicles. For this reason, the darker and thicker the hair, the better the effect.
The 6 weeks before your treatment is very important for you.
Be careful not to tan on your body and avoid sunbathing for at least 6 weeks before your laser procedure. Because this action can cause blisters and burns.
Correct the desired area before the laser, but avoid strips, waxing, bleaching, and electrolysis for 6 weeks before using a separate laser device.
Be sure to wash your body before the laser treatment so that the skin layer is free of anything and make sure that your body does not get wet before the procedure.
Avoid stressful situations and, if possible, caffeinated foods 24 hours before treatment.
Lasers can be used on the entire face, arms, underarms, back, abdomen, chest, legs, bikini, and almost all parts of the body except the eyes. There are various debates about the health risks of lasers. One of the disputes concerns the use of lasers on the female genital area and whether it can cause problems with the uterus, but there are no examples in this case. The laser is said to have a negative effect on the skin, but patients with skin problems directly under the hair laser have not been observed. It is important to note that sunscreen with spf 50 should be used after the laser and should not be exposed to direct sunlight.
Many people claim that they need laser treatment to permanently remove unwanted hair. Of course, this treatment is not carried out in one or two procedures. According to some studies, at least 4-6 laser hair removal sessions are required to see clear and defined hair removal results. Although this number depends on the amount of hair and body structure of different people. People with thick hair may need 8 to 10 laser hair removal sessions to permanently remove the hair.
The rate of hair loss varies in different parts of the body. For example, armpit laser at Mehraz Clinic requires less time and frequency to achieve satisfactory results, while leg hair removal requires more time.
Dermatologists believe that the likelihood of laser exposure increases when the patient has lighter skin and darker unwanted hair. Different devices are used in laser treatment, and understanding the differences between laser hair removal and the benefits of each is a major challenge for many who wish to use this method, which we describe below:
Alexandrite laser hair removal is very effective for patients with fair skin and dark hair. If you have darker skin, the alexandrite laser may not be right for you. The long-pulse alexandrite laser penetrates deep into the dermis (middle layer of the skin). The heat generated by the strands of hair builds up and disables active hair follicles during the growth phase, which allows you to achieve the effect of laser hair removal. The risk with this laser is that the laser can cause changes in skin pigmentation (darkening or lightening) and is not suitable for darker skin.
Nd-YAG lasers or long pulses are a safe and effective long term hair removal method for people with darker skin. In this laser, near-infrared waves penetrate deep into the skin and are then absorbed by the hair pigment. The new results show that the laser does not affect surrounding tissue. One disadvantage of the ND Yag laser is that it does not work on white or light hair and is less effective on fine hair. This laser is more painful than other lasers and there is a risk of burns, wounds, redness, skin discoloration and swelling.
