Laser hair removal is a form of hair removal that is long-lasting, but it destroys or damages the hair follicle. However, the hair can grow back, especially if the follicle is only damaged, not destroyed during the laser removal procedure.
It is for this reason that most doctors now recognize laser hair removal as a long-term solution rather than a permanent one.
Keep reading to find out how this treatment works, how long it will last for, and the cost involved in the procedure.
How does the laser hair treatment work?
When a woman has the procedure done on her armpits, and the laser hair removal destroys the follicle, it is permanent. The treatment uses light to target the pigment of each hair. The light travels down the shaft of the hair, into the follicle.
The heat destroys each follicle, and then the hair cannot grow back ever again.
Hair has a unique growth cycle which involves resting, then shedding, and then finally growing periods. Hair that has been recently removed will be in the resting stage and not be visible to the technician or the laser, in which case a person will have to wait for the hair to regrow before it can be removed.
Most people will need to have a few treatments over about 2 or 3 months.
Is it permanent?
Hair removed from a destroyed follicle will be permanent. What you need to remember is that it is possible in some people for some of the hair in the target area to grow back.
Over time, it is more than possible to have the area treated again so that the hair is less likely to grow back. It is even possible to make sure it never grows back.
Whether the hair grows back or not is determined by several factors, including the type of hair that regrows and the skills of the person performing the procedure.
Many people find that the hair that grows back is much lighter and not so noticeable as before. This is due to the fact that the laser might damage the follicle even if it does not destroy it.
If the follicle is only damaged, the hair is bound to grow back at some point. It is rather difficult to destroy every single hair, so many people will find some regrowth after treatment.
When regrowth does happen, it can be treated again, so you may need to have a few treatments.
How long will the laser removal last?
When the follicles are destroyed, hair removal is permanent. If the follicles are only damaged, the hair will grow back in time.
The time it takes to grow back depends on the hair cycle of a person, and every person’s growth cycle is different. Some people’s hair will grow faster than others. Any hair that is in it’s resting period will grow back faster than hair that is in a different cycle.
In general, people can expect a bit of hair regrowth within a couple of months. When this does happen, they can choose to have a few more treatments.
Does hair or skin color make a difference?
If a woman who has dark hair and a light complexion has laser hair removal, she can expect fewer treatments than other people. Hair removal works best for people who have dark hair and light complexions. The reason for this is that the contrast between the pigments is easier to see with the laser light.
People with light hair or dark skin will most likely find that they need more treatments to get the same effect.
In order to permanently remove hair, the technician will need to know how exactly to target the hair and which type of laser they will need. In 2013, there was research done that shows that lasers producing longer wavelengths work much better on dark skin.
Risks and side effects
While undergoing treatment, some people can experience stinging, burning, or discomfort. Most technicians now use a numbing cream on the skin being treated. There have, however, been cases where people have allergic reactions to numbing creams.
Minor side effects can include:
- Changes in skin color, especially in people with dark skin, which is normally tempory
- Reddish skin
- Crusting or blistering of the skin
- Sometimes people’s skin gets irritated from the treatment, and this could lead to the skin becoming scared. Skin that is damaged can become infected. Even though it is rare, some skin infections can become life-threatening.
Supplying the person doing the treatment with all your medical history, discussing the possible risks and benefits will help the provider to determine the correct treatment for you, which will also lower the risk of any side effects occurring.
After having laser hair removal done, people need to stay out of the sun. The sun can possibly irritate the skin, which will increase the risk of scars and blisters.
Anybody who experiences severe pain, fever, blisters, crusting, or any other sign of skin damage must get medical attention as soon as possible.
As many people will require a few treatments, they need to discuss how many and the costs involved with the person who will be performing the laser hair removal Langley treatment.
The total cost will depend on a number of factors, including who it is that will be doing the removal for you.
