Laser hair removal damages or kills the hair follicle, resulting in long-term hair removal. However, if the follicle is injured but not destroyed during the laser hair removal operation, the hair may return. As a result, many physicians now refer to laser hair removal as long-term rather than permanent hair removal. Continue reading to learn more about how laser hair removal works, how long it lasts, and how much it costs.
What is the procedure for laser hair removal?
Light is used to target the pigment in individual hairs in laser hair removal. The light passes through the hair shaft and into the hair follicle.
The heat from the laser damages the hair follicle, making it impossible for a hair to grow from it.
Hair has a distinct development cycle that includes phases of rest, shedding, and growth. Hair that has just been removed and is in the resting phase will not be visible to the technician or laser, therefore it may be necessary to wait until it regrows before removing it.
Laser hair removal usually involves numerous sessions over the course of two to three months for most people.
Is laser hair removal a long-term solution?
Hair removal from a follicle that has been damaged is permanent. People who have their hair removed should expect some hair to grow back in the treated region.
It is feasible to treat the area again in the future to limit the amount of regrowing hairs. It may even be feasible to get rid of all hair in rare circumstances.
Hair regrows depending on a variety of circumstances, including the type of hair that regrows and the expertise level of the individual who removes the hair.

When hair regrows, most individuals note that it is lighter and less prominent than before. This is because even if the laser fails to destroy the hair follicle, it may inflict damage to it.
The hair will regrow if a hair follicle is injured but not destroyed. Because destroying every single hair follicle is difficult, most people will experience some hair regrowth.
Hair can be treated again as it regrows, so patients who want to remove all of their hair may need numerous treatments.
Hair may be too light, too short, or resistant to treatment in some circumstances. Other hair removal treatments, such as plucking stray hairs, may be used in certain situations.
When it comes to laser hair removal, how long does it last?
When the hair follicle is destroyed, laser hair removal is permanent. Hair will ultimately regrow if the hair follicle is simply injured.
The length of time it takes for hair to regrow is determined on the individual’s hair development cycle. Hair grows faster in some persons than it does in others. Hair in a resting phase grows back more slowly than hair in a different phase.
Within a few months, most people might expect to see some hair regrowth. They can then choose to have further removal treatments.
Is there a difference in skin or hair color?
Hair removal works best on persons who have dark hair and a light complexion. Because of the pigment contrast, the laser is able to target the hair, go inside the follicle, and destroy the follicle more easily.
People with dark skin or light hair may require more treatments and may notice that their hair regrows more quickly.
To remove hair permanently, the technician must know how to target the hair and select the appropriate laser. Longer wavelength lasers work best on dark skin, according to research released in 2013 by Trusted Source.
Risks and side effects
Some people report burning, stinging, or discomfort during therapy. As a result, many technicians use a numbing lotion on the region they’re working on. Some people, however, may experience an allergic reaction or skin irritation as a result of the numbing treatment.
