Using a laser to remove unwanted hair is a non-invasive method. When it comes to minimally invasive cosmetic procedures, laser hair removal is a popular choice. If you want to get rid of unwanted hair on both large and minor parts of the body, this is a viable alternative for individuals who have a lot of it.
Using a laser to remove unwanted hair
A medical expert (a physician, physician assistant, or registered nurse) cleans the treatment area before the operation. A numbing gel is used if the region is susceptible. Everyone in the room must wear appropriate eye protection to avoid eye injury from the laser during the treatment.
A high-intensity laser beam is directed at the target location once the numbing gel takes effect. The operation will take longer if you need to treat a larger region. Small regions are done in minutes, but more significant portions like the chest might take up to an hour.
One of the most common complaints from patients is that they feel like they have a sunburn. Laser radiation can cause the hair to evaporate and emit a sulphurous scent as it does so.
Getting ready for a laser hair treatment
Before your doctor’s visit, you should be given detailed advice on preparing for it. When these recommendations are followed, the operation is more successful, with fewer adverse effects. Here are a few general suggestions:
- A few days before the surgery, avoid the sun’s rays. The use of hair removal by laser on skin that has been exposed to the sun for an extended period is unsafe.
- Avoid causing skin irritation.
- Avoid using hair removal methods such as waxing or plucking.
- Aspirin and other anti-inflammatory medicines, such as ibuprofen, might increase the risk of bleeding.
- A skin-bleaching substance may be used if you have light or dark skin in the treatment region.
What is the procedure for hair removal by the use of a laser?
It takes a fraction of a second for a pulse of the laser to cure a large area of hair simultaneously. Every quarter of a second, the laser can treat an area the size of a quarter. While the upper lip is treated in less than a minute, it can take up to an hour to treat vast regions such as the back or legs.
Hair follicles, which are tiny spaces in the skin from which hair develops, target hair removal, using focused light to destroy the hair follicles. When the hair follicle ingests the laser’s melanin pigment, the hair is quickly vapourized.
People with dark hair and light complexion are prime candidates for laser hair removal because the colour in their hair attracts the laser.
Hair removal is more difficult for those with dark skin since their hair cannot be seen against their skin. A laser hair removal treatment will have no impact on hair that is light in colour, grey, or white.

After laser hair removal, what can you expect?
Most patients can return to their daily routines immediately following the surgery. Wearing sunscreen after the operation is just as crucial as wearing it before. It will help alleviate any additional discomfort.
A decrease in hair follicles might be expected soon following the operation. You may notice an increase in hair growth in the treated region two to eight weeks following the hair removal. Hair follicles react differently to laser treatment, so this isn’t always possible.
After the first treatment, most patients see a 10% to 25% decrease in hair growth. Permanent hair thinning might take anywhere from three to eight treatments. Before the operation, your doctor will be able to tell you how many treatment sessions you may require. You’ll probably want to come in for a weekly touch-up session to keep the results.
