You will find currently 2 known instances where you will find a possibility that laser hair removal will make hair re-grow thicker and darker than it was before treatment. Please keep in mind that one is preventable while the other is so rare, the probability of it happening are very small.
The initial scenario can occur to anyone, though the majority of people that choose laser treatment will not be conscious of this risk just before treatment. To be able to perform 【激光脫毛】, the technician will require that you shave the preferred area a couple of days prior to your appointment. The hair must be as short as is possible, but still be visible, to ensure that the laser to operate to its full potential. Unfortunately, some areas that folks wish to have lasered, (like the face and back), contain a mixture of the dark coarse hairs that they want gone and “peach fuzz” (the extremely fine and colorless hairs which cover lots of your body). When shaving this region when preparing for laser treatment, the peach fuzz that is certainly present also gets shaved. With shaving, hairs have a tendency to grow back thicker, darker, and faster with every shave. The fine hairs which were once unnoticeable may now start to appear darker upon return, which may make the illusion more and more hair is starting to grow after you have laser treatment.
The second instance is really a medical problem called “paradoxical hypertrichosis”. It is a rare reaction that can be experienced after hair laser removal treatment. As paradoxical hypertrichosis, (or postlaser hypertrichosis), continues to be a somewhat new and extremely rare condition, there is not a great deal of research done on the subject. It is not easy to determine what the exact reason behind this phenomenon is. Some specialists advise that this unwanted the growth of hair could be caused by extremely low intensity laser or IPL treatments at levels that are too low to be effective and actually find yourself stimulating new the growth of hair in the hair bulb instead of destroying the hair bulb completely. Others claim that ethnic background may be a factor as reports have learned that this reaction has a tendency to happen more in individuals with skin types 3, 4, and 5 (olive and darker skin) than it will in individuals with lighter skin. Additionally there is the possibility that particular medication can increase the risk of paradoxical hypertrichosis if taken concurrently as the laser treatments. As you have seen, individuals with this condition are extremely few and far between that it must be difficult to get a proper sampling.
Regardless of the suggested factors of paradoxical hypertrichosis, it is rather important to find a laser technician which is skilled and capable to perform your treatments. They need to be knowledgeable enough to ascertain the correct laser intensity setting for your particular hair and skin attributes. Too low may be ineffective and cause side effects. Intensity that is certainly too much could cause negative effects such as minor burns and skin discoloration. The ideal balance will safely ujuvnd effectively remove your unwanted hair to make your hair laser removal experience a good one.
Even though it is unusual that 【激光脫毛】 will make the hair re-grow thicker, this has been recognized to happen sometimes. In case you are concerned, or if you know that this area you need to have treated includes peach fuzz, perhaps a different method like electrolysis hair removal would be a better alternative for you personally. Electrolysis fails to require you to shave just before treatment so you do not run the chance of shaving over any peach fuzz and causing it to develop back thicker. Each hair is individually treated so you may not run the chance of any other area of the skin being treated other than where you would like to be treated.
