Laser hair removal is a long-lasting form of hair removal that damages or destroys the hair follicle. However, hair can grow back, especially if the follicle is damaged and not destroyed during the laser hair removal procedure. This is why laser hair removal is now referred to as long-term hair removal rather than permanent hair removal.

Read on to find out how laser hair removal works, how long it lasts.

How does laser hair removal work?

Laser hair removal uses light to target the pigment in individual hairs. The light travels down the hair shaft and into the hair follicle. The heat from the laser light destroys the hair follicle, and the hair can no longer grow. Hair follows a unique growth cycle that includes periods of rest, shedding and growth. Recently tweezed hairs that are in a resting phase will not be visible to the technician or the laser, so a person may need to wait for them to grow back before removing them. For most people, laser hair removal requires multiple treatments over a 2-3 month period.

Is laser hair removal permanent?

Hair removal from a destroyed hair follicle is permanent. However, people who undergo waxing can expect some hair in the targeted area to grow back. Over time, the area can be treated again to reduce the number of hairs that grow back. In some cases, it is even possible to remove all the hair. Whether or not hair regrows depends on many factors, including the type of hair that regrows and the skill of the person removing it. Most people find that when the hair grows back, it is lighter and less noticeable than before. This is because the laser can damage the hair follicle even if it fails to destroy it.

If a hair follicle is damaged but not destroyed, the hair will eventually grow back. It can be difficult to destroy every hair follicle, which is why most people will see their hair grow back. When hair grows back, it is possible to treat it again, so people who want to remove all hair may need multiple treatments.

In some cases, the hairs may be too light, too short or resistant to treatment. In these cases, a person may choose to use other methods of hair removal, such as removing loose hair.

How long does laser hair removal last

Laser hair removal is permanent when the hair follicle is destroyed. When the hair follicle is only damaged, the hair eventually grows back. The time it takes for hair to regrow depends on each person’s own hair growth cycle. Some people grow hair faster than others. Hair that is in a resting phase grows back more slowly than hair that is in another phase.

Most people can expect some hair regrowth after a few months. Once this happens, they can opt for further hair removal treatments.

Does skin or hair color make a difference?

People with fair complexions and dark hair may need fewer treatments than others. Waxing works best on fair-skinned people who have dark hair. Indeed, the pigment contrast makes it easier for the laser to target the hair, move through the follicle and destroy it. People with dark skin or light hair may need more treatments than others and may find that more hair grows back.

To permanently remove hair, the technician must know how to target the hair and choose the right type of laser. Lasers that produce longer wavelengths work better on dark skin.

Side effects and risks

During treatment, some people experience burning, tingling, or discomfort. For this reason, many technicians apply numbing cream to the area they are treating. However, some people may have an allergic reaction or skin irritation in response to the numbing cream. Minor side effects are common and may include:

– changes in skin color, especially in dark-skinned people, which are usually temporary
– redness of the skin
– the formation of blisters or crusts on the skin.

Sometimes irritation from waxing can cause scarring. Damaged skin can also become infected. Although rare, skin infections can spread and be life-threatening. Providing a detailed medical history and discussing the risks and benefits can help the provider determine the right treatment, reducing the risk of serious side effects. After hair removal, the person should avoid exposure to the sun. The sun can irritate the skin, increasing the risk of blisters and scarring.

People who experience severe pain, fever, scabs, blisters, or other signs of skin damage or infection should see a doctor. Laser hair removal can significantly reduce the amount of hair on a person’s body. In most people, some hair grows back over time.

Even when hair grows back, there will be less overall, resulting in a smoother appearance. To get a realistic idea of ​​what you can expect from laser hair removal, discuss treatment goals with a hair removal specialist. Some skin tones and hair types perform better than others. The only way to know for sure what to expect is to speak with a doctor, dermatologist, or other qualified practitioner.
