To get rid of unwanted hair permanently, Laser Hair Removal (although very high-tech) is one of the most popular choices. But the capability of Laser Hair Removal depends on numerous factors, encompassing (i) the type of laser being used, (ii) the color of your hair, (iii) the color / type of your skin and (iv) the stage of the hair in the hair growth cycle. There are 5 different types of lasers that are currently used to remove hair. Some lasers suit light skin, some lasers suit dark skin, some suit light hair and some suit dark hair. And even if you get it all correct, you still might not end up with permanent hair removal right away. You see, the answer is in the hair growth cycle, and more especially, what phase of the cycle your unrequired hair is in.... sounds tricky - it is ! Before we come to know the hair growth cycle, it is essential to comprehend just how Laser Hair Removal actually works. That is, to comprehend precisely how you can obtain permanent hair removal, getting an appreciation of the laser process is imperative. The laser process doesn't actually physically remove the unwanted hair. The energy from the laser actually travels through the skin, and is drawn in by the pigment in the hair follicle and shaft. When this energy is soaked into a hair, the follicles are damaged, which then impairs that distinct hairs ability to grow. Eventually the hair will fall out, typically within a matter of weeks. Getting an understanding of how the laser works is important. You need to always remember that the laser does not just make the hair fall out right away. It actually impairs the capability of a hair to grow, causing it to eventually fall out. Now that we have a brief understanding of how the laser operates, it is time to get an insight into how the hair growth cycle relates to the permanent nature of laser hair removal. If the hair is in the right stage of the growth cycle, then permanent removal is more likely, otherwise further Laser Hair Removal sessions will be necessary. You see, the hair growth cycle encompasses three stages, and the permanency of Laser Hair Removal is more predictable when the hair is in one stage particularly - the growth stage. The growth cycle of hair includes 3 distinct stages : (1) Active/Anagen (2) Regressive/Catagen (3) Resting/Telogen. Laser hair removal is most potent 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 expectation of permanent hair removal is less. No two people are the same, and that rule applies for hair growth because so many factors, including age, metabolism, weight and genetics can affect the way a person's hair grows. However, disregardful of how these factors affect individual hair growth, hair itself grows through three clear-cut stages: 1. The ACTIVE or ANAGEN growth phase, consists of approximately 85 % of our body hair at any given moment in time and can last up to several years. During this stage, the hair shaft and follicle has an affluence of pigment and is most affected by the laser light. 2. The REGRESSIVE or CATAGEN phase is the phase 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 point 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 becomes visible. 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. So now we understand the growth cycle of hair, it needs to be asked, "Is permanent hair removal actually possible?" The answer is Yes, Laser Hair Removal can definitely provide a level of permanent nature. As you can see, if a hair in the Active/Anagen stage is exposed to the laser, then that hair will more than likely be killed permanently. If a hair that is in either of the other 2 stages is exposed to the laser, then that hair will most likely be killed, but the new hair coming through will still carry on growing. 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 session will permanently remove all of your problem hair, but the likelihood is that you will need numerous 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 realizable !
