Laser Hair Removal - How it Actually Works

Simply put, laser hair removal is one of the techniques used to get rid of hair growing where it is not desired. And many people, hearing about it for the first time, express an interest in knowing how it actually works. This they do, mainly because they are keen on making use of it - and for one, they want to be sure that actually works (as there are many things on sale nowadays that actually don't work). If it works, they want to be sure that the mechanism via which it works is one that is 'palatable' to them. And if that is the case, they also want to be sure that it won't leave them with obnoxious side effects that they have to struggle with all their lives. A sensible person wants to lose unwanted hair, alright, but definitely not at any cost to their body.

So how does laser hair removal actually work?

Well, the first key to understanding how laser hair removal actually works is getting to appreciate that whenever you hear of something being termed as a 'laser technology' you automatically know that it is something to do with light. So there we have the basic foundational fact: that in laser hair removal it is light energy that is used to make possible the hair loss.

But how exactly does light make possible hair loss?

In order to understand how light makes possible hair loss in the laser hair removal, it is worth pointing out that it is not the usual type of light (in raw form) that is applied here, but rather light that has been 'collected and concentrated' so that it can be beamed as a laser. There is special equipment that makes this possible. During the beaming, the light is not just let out, but rather the output is controlled, and the light released in pulses, which make possible the treatment.

Now as we all know, most things that emit light have a burning effect. Mostly, this tends to be destructive. But in laser hair removal (and other laser treatments for that matter), the heating effect is specially harnessed to make it beneficial. In the case of laser hair removal, for instance, it has come to be learnt that it is possible (by changing variables such as frequency and wavelength), to let out the light pulses in such a way that they can damage the material that causes the growth of hair (where it is unwanted in this case), underneath the skin, without actually damaging the rest of the skin. In other words, it is a selective technique. It chooses what to damage (unwanted potential hair follicles) and what to preserve (the rest of the skin).

In terms of effectiveness, laser hair removal is definitely a hair removal technique that has shown what is widely seen as remarkable efficacy - at least as compared to the other available hair removal techniques. As we can see from that exploration of its working mechanism, it is a technique that would work for pretty much everybody.

In terms of a safety profile, laser hair removal is relatively safe; but with a tendency to cause (short-lived) pigmentation changes and itching, sometimes accompanied by a little swelling in the area where it is done. These usually abate within a few days, though. More worrisome, if the treatment is not carried out correctly, is the risk of general skin burn. But then again, if the right type of a laser is used, and it is correctly adjusted for person to undergo the treatment, this is usually nothing to worry about.
