A Quick Description of Laser Hair Removal
By Bobby Sawyer
Laser hair removal works by using a pulsating, intense beam of light to get rid of any unwanted hair. Even though the process is referred to as laser hair removal, it doesn't actually use lasers. It is just a beam of light that travels down the hair into the follicle. What this does is creates heat in the follicle which slows down any further growth. The beam of light is attracted to the pigment in the hair, which acts as a conductor. Because of this, laser hair removal works best on people with light skin and dark hair. However, technological advancements in the field have created lasers that are starting to work on all skin types and hair pigments. A single treatment alone will usually not eliminate hair growth. It will slow it down and prevent re-growth for months, even years. To permanently prevent hair growth, multiple treatments are required.
Side effects are rare, especially with the newer laser treatments. But side effects, if any, usually come in the form of skin irritation. This is mainly due to the heat involved. If your skin has ever been overheated to the point where you get a heat rash, this is comparable. But, again, side effects are rare.
In general, because the laser targets hair with darker pigments, people with darker skin tones or a tan will be harder to treat. While lasers are coming out now that work on darker skin tones, they're still not as common as lasers that work on lighter skin tones. This will change, but it's gonna take some time. It is recommended that people stay out of the sun for around 4 weeks prior to treatment, to ensure skin tone isn't too dark. And after the treatment it is recommended you don't do any kind of physical activity that will make you sweat a lot, because this will irritate the skin. It is also recommended that you stay out of the sun for several weeks, again so the skin is not irritated.
Nothing is required for after the treatment. Sometimes, right after the treatment, people will experience a little redness. This is to be expected because of the heat involved, but will only last a few hours until your skin returns to normal color. Petroleum jelly is recommended in order to moisturize if the skin experiences any dryness.
Finally, most laser hair removal should only be performed by trained professionals. There are, however, laser hair removal machines that can be purchased and used in the comfort and convenience of your own home. The No No hair removal machine is a very popular and affordable option that offers a 60 day risk free trial.
