What is laser hair removal
Laser hair removal is a permanent form of laser hair removal that damages or destroys the hair follicles. If during laser hair removal, the hair follicles are damaged but not completely destroyed, there is a high chance of hair regrowth. Therefore, many doctors now regard laser hair removal as permanent hair removal rather than permanent hair removal.

What is the principle of laser hair removal?
Laser hair removal uses a laser to target the pigment in each individual hair. The laser travels down the hair, to the root and into the follicle.
The heat from the laser destroys the hair follicles so that the hair does not grow back.
Hair follows a unique growth cycle that includes a resting, shedding, and growing period. Shortly after epilation, the hairs are in a dormant stage where they cannot be recognized by the technician or the laser. Therefore, in order to continue hair removal, you have to wait for the hair to grow back.
For most people, laser hair removal requires multiple treatments over the course of 2 to 3 months.
Is laser hair removal permanent?
If the hair follicles have died, hair removal is permanent. However, regrowth of hair from the epilation site is to be expected.
Over time, people can treat the same area of hair removal again, reducing the amount of hair that regrows. In some cases, it is possible to completely remove all hair.
Whether the hair will grow back depends on many factors, including the type of regrowth and the technique of the hair removal technician.
Most people find that the hair that grows back is thinner and lighter than before. This is because the laser damages the hair follicle, even if it is not necrotic, the hair follicle is already damaged.
If the hair follicle is damaged but not dead, the hair will eventually grow back. It’s not easy to hit all the follicles one by one, so most people’s hair will continue to grow even after laser hair removal.
In some cases, the hair may be too light in color, too short in length, and too durable to handle. At this point, people can choose to use other methods of hair removal, such as plucking it.
How long does laser hair removal last?
As mentioned above, laser hair removal is permanent when the hair follicle is necrotic, and if the hair follicle is just damaged, the hair will grow back. How long it takes for hair to grow back depends on each individual’s unique hair growth cycle. Some people’s hair grows faster than others. Hair in the resting phase grows slower than hair in other phases.
Does the skin color and hair color affect the hair removal effect?
Laser Hair removal works best on people with light skin tones and dark hair. Because the pigment contrast between skin and hair is large, the laser can easily locate the hair, enter the hair follicle and then break it down.
People with darker skin and lighter hair may need more epilation treatments and regrow more hair.
To remove hair permanently, the technician must know how to target the hair and choose the correct type of laser. According to a study published in 2013, longer-wavelength lasers work best on people with darker skin tones.
