A wide range of lasers and pulse lights are used to remove excess hair. The mechanism of action of these methods is based on prolonging the sleep phase of the hair roots and subsequently reducing the volume of excess hair in the area. Before doing laser hair removal, you should pay attention to the following:
- Avoid skin discoloration during treatment, either with the sun or tanning devices.
- Do not remove excess hair from the area for two weeks before starting treatment (razor or shaving cream is allowed).
- Laser hair removal on women’s faces should be done at the same time as checking for hormonal problems to get the best results.
Common lasers are used to destroy hair follicle are: Diode, Alexandrite, as well as pulse lights known as IPL. The heat generated by these devices absorbs the hair follicles and destroys the hair cells in the area, resulting in a reduction in the amount of hair and thinning of the remaining hair.
Duration of action
The number of laser sessions in each area, depending on the patient’s hair color and skin, is between 4 and 10 sessions at regular intervals.
Laser hair removal is performed in most parts of the body without the need for anesthesia and in some sensitive areas under anesthesia with topical ointments.
Inpatient / outpatient status
Immediately after removing excess hair, the patient can return to his daily work.
Possible side effects
Inflammation, swelling, and temporary redness at the laser site are Possible side effects of laser hair removal.
If you come in contact with sunlight and do not use sunscreen properly, dark or light spots may appear in the treatment area. In very rare cases, hirsutism (abnormal growth of hair on a person’s face and body, especially on a woman) has been reported following laser hair removal. Inflammation, swelling, and redness, and in some cases even sores, occur in the area, which can be treated with prescribed medications within a week.
- Due to the fact that the laser can cause inflammation and redness, so do not use cosmetic products on the area for 48 hours after treatment.
- Avoid cutting hair and tanning methods during the treatment period.
- Repeat treatment is required 1 to 3 years after the first stage.
- Washing the treatment site immediately after the laser is not prohibited.
- In case of redness and inflammation, use the healing drugs.
- In cases where laser hair removal is done on the face, sunscreen care is essential.
- If you have a history of herpes, be sure to use antiviral medications.
At the end of the laser hair removal procedure, 70 to 90% of the hair in the area will be temporarily removed. If necessary, the laser will be performed again in 3 years.
With each laser hair removal session, 15 to 20 percent of the treated area’s hair falls into the dormant phase. At best, 90% of hair growth stops in 1 to 3 years.
