How Does Laser Hair Removal Procedure Work

In the following article we’ll mention a vital topic that’s “How Does Laser Hair Removal Procedure Work?” let’s discuss within the article given below:

So What Is A laser

LASER actually means “Light Amplification by Stimulated Emission of Radiation”, complicated right.

Well, in simple language a laser is a very strong and very focused beam of light. Lasers are used in a huge range of applications, from industry, to communications, to mapping. If we talk about Laser hair removal it actually relies on specially designed medical grade lasers that are really safe to use on human skin.

The Three Stages Of Hair Growth

If you want to understand how exactly laser hair removal works you first need to understand the different stages of hair growth. Hair actually has 3 different stages of growth and not all hairs grow at the same time.

Three different stages of hair growth:

Anagen – the active growth phase. At this stage, the bottom of the hair follicle (the bulb) is attached to the dermis and its blood supply through the dermal papilla.

Catagen – the transition phase. The hair follicle begins to die and enters the catagen phase

Telogen – the resting phase. In this particular phase, the remains of the hair bulb are quite inactive and thus the attached hair falls out really easily.

How Do Lasers Remove Hair

Laser hair removal actually works because the light of the laser beam can be converted to heat in order to remove the hair. The light is really attracted to the pigment (i.e. melanin) in the hair. Dark pigment actually absorbs the light and the converts it to heat. After which the heat then affects the hair follicles to prevent hair growth.

So as to destroy a hair follicle, the bulb of the hair follicle where the blood actually supplies the hair with oxygen to grow and also the stem cells that are responsible for hair regeneration, both need to be destroyed. To be able to do this, a temperature of about 70 degrees needs to be reached.

The darker and the thicker a hair is the more pigment it will actually hold, and thus the more light it will absorb making it easier to remove the hair. This is why it is important that you don’t wax or pluck your hair before a treatment, because if there is no hair there, there is no way for the laser light to treat that hair follicle.

So to recap, what happens is that the light is emitted, is then absorbed by the pigment in the hair, travels through the hair and is converted to heat and destroys the root. That hair is destroyed and does not grow back! It’s just so simple and effective.

Is Laser Hair Removal Permanent

There are 3 main factors which will actually affect whether or not we are able to achieve permanent hair removal.

Only hairs in the growing stage (hairs that are in the anagen phase) can actually be treated successfully, however not all hairs grow at the same time. For example, at any one specific given time on our body, only about 20-40% of hair is growing (in anagen phase) the others are either in the transition or resting phase. This is why a course of treatments is required to get the different hairs as they enter the growing stage. Treatments are every 8 weeks for the body and 4 weeks for the face.

Secondly, only hair that has pigment can actually be treated. If you actually have white, grey, blond or red hair, it’s important that you understand these won’t respond, as there’s no dark pigment in these hairs to hold that light. Thus the laser cannot 

actually generate enough heat in order to destroy the hair. Also the finer and lighter the hair, the harder it’ll be to attain permanent hair removal as there’s less pigment in the hair.

The thicker and darker the hair, the more pigment it contains, which implies the light will actually be absorbed, convert to heat and reach a temperature of about 70 degrees, and therefore destroy the root of the hair. If this temperature isn’t reached, the treatment will only damage the hair which can actually result in lighter finer hairs growing back. In this case the hair follicle won’t be effectively destroyed.

And the third factor is skin colour. The lighter your skin the higher the fluence (intensity) you’ll be treated with. If your skin is darker, the therapist will actually need to use a lower the fluence to treat you. This is because laser light doesn’t know the difference between the pigments in your hair or your skin, so if you actually have a tan you increase the chance of burning your skin. It’s best to keep your skin as light as possible, because you can then be treated on a higher fluence. And that’s why if you have a tan, you need to stay out of the sun, wear sunblock every day and start your treatment when the tan is gone.
