Why doesn’t Laser Hair Removal always Permanently Remove Hair?

By: Jim McDonald

To get rid of unwanted hair permanently, Laser Hair Removal (although very high-tech) is one of the most popular choices. But the effectiveness of Laser Hair Removal relies on numerous factors, embracing (i) the kind of laser being used, (ii) the color of your hair, (iii) the color / variety of your skin and (iv) the stage of the hair in the hair growth cycle.

Today there are 5 different types of lasers that can be used to remove unwanted hair. Your skin type and you hair color will help to determine the most effective laser for you. And even if you get it right, you still might not be left with permanent hair removal in the short term. You see, the answer is in the hair growth cycle, and more distinctly, what phase of the cycle your unwanted hair is in.... sounds tricky - it is !

Before we get to know the hair growth cycle, it is essential to understand just how Laser Hair Removal actually works. That is, to appreciate exactly how you can accomplish permanent hair removal, acquiring knowledge of the laser process is essential.

The laser process doesn't actually physically remove the unwanted hair. The energy from the laser actually travels through the skin, and is soaked up by the pigment in the hair follicle and shaft. When this energy is absorbed into a hair, the follicles are damaged, which then impairs that particular hairs ability to grow. Eventually the hair will fall out, typically within a matter of weeks.

Getting an appreciation of how the laser operates is important. You need to always remember that the laser does not just make the hair fall out on the spot. It actually impairs the ableness of a hair to grow, causing it to eventually fall out. Now that we have a brief understanding of how the laser works, it is time to get an insight into how the hair growth cycle relates to the permanency of laser hair removal.

If the hair is in the wrong stage of the growth cycle, the laser might not provide permanent removal after a first treatment. You see, the hair growth cycle encompasses three stages, and the permanence of Laser Hair Removal is more predictable when the hair is in one stage particularly - the growth stage.

The hair growth cycle comprises three stages : (1) Active/Anagen (2) Regressive/Catagen (3) Resting/Telogen. Laser hair removal is more effective in the Anagen stage where the hair contains the most pigment, and is most sensitive to the laser light. If the laser treatment is applied when the hair is in either of the 2 other phases, then the eventuality of permanent hair removal is less.

Although hair is primarily the same thing from person to person, the way an individual's hair grows is so unique, owing to many factors including: weight, metabolism, age, genetics and environmental conditions. However, regardless of how these factors act on individual hair growth, hair itself grows through three distinct phases:

1. The ACTIVE or ANAGEN growth phase, comprises approximately 85 % of our body hair at any given point in time and can last up to several years. During this stage, the hair shaft and follicle has an abundance of pigment and is most sensitive to the laser light.

2. The REGRESSIVE or CATAGEN phase is the stage during which the hair stops growing but is not yet shed. This phase often lasts a few weeks comprising about 3 - 4% of our total body hair at any given moment in time. The laser will work in this stage, but if it is late in this part of the cycle, a new hair might already be coming through and the new hair will not be affected by the laser.

3. The RESTING or TELOGEN phase lasts 5 - 6 weeks, at the end of which the hair falls out and the new hair emerges. The new hair mightn't be affected by the laser because it will not have pigment in it yet, remembering that the laser actually relies on the pigment to find the hair. Approximately 10-13% of our body hair is in this phase at any one time.

Now that we have a brief understanding of the hair growth cycle, it must be asked, "Is Laser hair removal a permanent process?" The answer is Yes, Laser Hair Removal can certainly provide a level of permanent nature. As you can see, if a hair in the Active/Anagen stage is subjected to the laser, then that hair will most probably be killed permanently. If a hair that is in either of the other 2 stages is revealed to the laser, then that hair will more than likely be killed, but the new hair coming through will still continue to grow.

So the tip on Laser Hair Removal is that you will most likely require a few sessions to ensure that your unwanted hair is removed permanently. You could be lucky - your first Laser hair removal treatment will permanently remove all of your unwanted hair, but the eventuality is that you will need a number of sessions at set intervals to ensure that you get to the hair when it is in the first stage of growth. And that is all there really is to comprehend, permanent Laser Hair Removal is definitely achievable !
