Can we remove hair permanently by laser?
Shaving, plucking, or waxing hair can often be time-consuming. Many people turn to laser hair removal as a solution to take care of unwanted facial and body hair. But, is laser hair removal a permanent solution?
After you have your first laser hair removal treatment, you will see a reduced number of hairs immediately. Hair growth may increase in the treated area from 2 to 8 weeks after since not all hair follicles respond equally to the treatment. It usually takes 3 to 8 sessions to achieve permanent hair loss. You may also need touch-up sessions about once a year.
Laser hair removal permanently reduces hair. Even if some hair grows back, it should be less noticeable as well as finer and lighter than it was before your treatments.
How does laser hair removal work?
Laser hair removal uses light to target the pigment in individual hairs. The light travels down the shaft of the hair and into the hair follicle.
The heat from the laser light destroys the hair follicle, and a hair can no longer grow from it.
Hair follows a unique growth cycle that involves resting, shedding, and growing periods. Recently removed hair that is in a resting phase will not be visible to the technician or laser, so a person may need to wait until it regrows before removing it.
Hair removal from a destroyed hair follicle is permanent. However, people who undergo hair removal can expect that some hair in the targeted area will grow back.
Over time, it is possible to treat the area again to reduce the number of hairs that regrow. In some cases, it may even be possible to eliminate all hair.
Whether or not hair grows back depends on numerous factors, including the type of hair that regrows and the skill of the person removing the hair.
Most people find that when hair regrows, it is lighter and less noticeable than it was before. This is because the laser may damage the hair follicle even when it fails to destroy it.
If a hair follicle is damaged but not destroyed, the hair will eventually regrow. It can be difficult to destroy every single hair follicle, so most people will see some hair regrowth.
When hair regrows, it is possible to treat it again, so people who want to remove all the hair may need several treatments.
In some cases, hair may be too light, too short, or resistant to treatment. In these cases, a person might choose to use other hair removal methods, such as plucking stray hairs.
Why Does Hair Still Grow After the Treatment?
Whether hair comes back depends on many aspects, including the hair type that regenerates and your commitment to manual hair removal methods. After laser treatment, new hair growth becomes thinner and less noticeable. The laser will damage the hair follicle even though it doesn’t kill it. The hair will gradually recover if a follicle is damaged but not completely lost. Every hair follicle can be challenging to eradicate. For this reason, most people who undergo the treatment still notice regrowth.
Hair grows in stages. Your hair produces the pigment in the active cycle, which gives it its color, and the laser targets this pigment. Laser treatments for follicles in the active stage are most successful. The energy of the laser won’t harm follicles that are inactive or dormant. Waiting a few weeks between each treatment will enable more hair to shift from dormant into the active stage of development. Thus, repeat treatments will allow more follicles to be eradicated.
