Laser hair removal is the process of removing unwanted hair with laser light that destroys the hair follicle. Once the root is destroyed, it can’t produce more hair.
Laser hair removal is widely practiced in clinics and even at homes with home laser hair removal devices. It has a specific wavelength and pulse to obtain the optimal effect on a targeted tissue with minimal effect on the surrounding area because lasers can selectively heat dark target (melanin) in the follicle while not heating the rest of the skin.
Using highly concentrated energy hair follicles are targeted and destroyed with the minimal discomfort. This noninvasive method is used for permanent reduction of unwanted facial or body hair.
Today, laser hair removal is one of the most common aesthetic procedures because it leaves the skin looking smooth and silky.
Most popular laser types
- Diode – this laser is very effective for light and dark skin.
- Alexandrite – this is the fastest of all lasers and works best for treating larger body areas on patients that have light to olive complexions.
- ND:YAG – long pulse laser can safely be used on all skin types, including tanned skin. It’s less effective for light or fine hair when compared to other types of lasers.
The best areas for laser hair removal
Although laser works on all body parts, the best results are in bikini area, lip, chin and underarms.
Candidates for laser hair removal
Laser hair removal works best on thick, coarse and dark hair. That said, it can take a little longer to fully work on thicker hair.
Medications you need to avoid beforehand
The laser hair removal is incompatible with certain meds. You should avoid medications that are photosensitive at least one week prior to the treatment. Also the patient shouldn’t be using skincare with strong actives such as retinoids and alpha hydroxyl acids. These ingredients can increase a skin cell turnover, making skin more vulnerable to the sun and irritation during the treatment period.
How many sessions do you need?
Everybody is different, so the amount of the sessions it takes varies per individual. Lasers work best when the hair is its active growth rate. Depending of the part of the body you are treating it can take longer or shorter. On average clients need 6-9 treatments for full hair removal.
The importance of attending all sessions
One of the biggest mistakes people make is not completing the necessary amount of the sessions. Because once the hair growth slow down clients don’t follow through.
What to do when you have a period?
You shouldn’t cancel your treatment due to your period. It’s very important to stay consistent with treatment, even if the woman is menstruating and wants to treat her bikini area, she must follow through. She just needs to wear a tampon.
It’s important to avoid sun exposure and to use sunscreen. Any hair growth between session should be shaved off not waxed or threaded.
