There are currently 2 known instances where there exists a possibility that laser hair removal will make hair grow back thicker and darker than it was before treatment. Please remember that one is preventable while the other is so rare, the chances of it happening are very small.
The very first scenario can happen to anyone, though the majority of people that choose laser treatment might not be mindful of this risk prior to treatment. To be able to perform 【激光脫毛】, the technician will need you to shave the preferred area a day or two before your appointment. The hair must be as short as you can, yet still be visible, to ensure the laser to function to its full potential. Unfortunately, some areas that individuals want to have lasered, (such as the face and back), contain a combination of the dark coarse hairs they want gone and “peach fuzz” (the extremely fine and colorless hairs that cover plenty of our body). When shaving this place in preparation for laser treatment, the peach fuzz which is present also gets shaved. With shaving, hairs tend to re-grow thicker, darker, and faster with every shave. The fine hairs which were once unnoticeable may now start to appear darker upon return, which can produce the illusion more hair is starting to grow after having laser treatment.
The next instance is a medical problem called “paradoxical hypertrichosis”. It really is a very rare reaction that can be experienced after hair laser removal treatment. As paradoxical hypertrichosis, (or postlaser hypertrichosis), continues to be a relatively new and very rare condition, there is not a lot of research done on the subject. It is not easy to find out what the exact reason behind this phenomenon is. Some specialists suggest that this unwanted the growth of hair can be caused by extremely low intensity laser or IPL treatments at levels that are too low to work and also find yourself stimulating new hair growth within the hair bulb as opposed to destroying your hair bulb completely. Others claim that ethnic background might be a factor as studies have learned that this reaction has a tendency to happen more in people who have kinds of skin 3, 4, and 5 (olive and darker skin) than it can in people with lighter skin. There is also the chance that certain medication can increase the potential risk of paradoxical hypertrichosis if taken at the same time since the laser treatments. As you can see, sufferers of this condition are so few and far between that it is difficult to get a proper sampling.
Regardless of the suggested factors of paradoxical hypertrichosis, it is very important to find a laser technician which is skilled and capable to perform your treatments. They must be knowledgeable enough to discover the correct laser intensity setting for the particular hair and skin attributes. Too low may be ineffective and cause adverse effects. Intensity which is too high could cause unwanted effects including minor burns and skin discoloration. An ideal balance will safely ujuvnd effectively remove your unwanted hair to make your laser hair removal experience an optimistic one.
Even though it is very rare that 【激光脫毛】 will make your own hair re-grow thicker, it has been recognized to happen sometimes. If you are concerned, or once you learn that this area you want to have treated includes peach fuzz, perhaps a different method like electrolysis hair removal would be a better alternative to suit your needs. Electrolysis will not require that you shave before treatment so you may not run the chance of shaving over any peach fuzz and causing it to grow back thicker. Each hair is individually treated so you may not run the risk of every other area of the epidermis being treated apart from where you want to be treated.
