You can find currently 2 known instances where there is a possibility that laser hair removal can 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 probability of it happening are very small.
The very first scenario can occur to anyone, though the majority of people that opt for laser treatment might not be aware of this risk just before treatment. To be able to perform 【激光脫毛】, the technician will require you to shave the desired area a couple of days just before your appointment. Your hair must be as short as is possible, yet still be visible, to ensure that the laser to operate to the full potential. Unfortunately, some areas that individuals wish to have lasered, (like the face and back), contain a blend of the dark coarse hairs that they want gone and “peach fuzz” (the extremely fine and colorless hairs which cover lots of the body). When shaving this place in preparation for laser treatment, the peach fuzz which is present also gets shaved. With shaving, hairs have a tendency to grow back thicker, darker, and faster with every shave. The fine hairs that were once unnoticeable may now commence to appear darker upon return, which could make the illusion more hair is beginning to grow after having laser treatment.
The second instance is a condition 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 fairly new and extremely rare condition, there has not been a great deal of research done on the subject. It is not easy to find out what the exact reason behind this phenomenon is. Some specialists claim that this unwanted hair regrowth can be brought on by extremely low intensity laser or IPL treatments at levels which are too low to work and also end up stimulating new the growth of hair in the hair bulb instead of destroying the hair bulb completely. Others suggest that ethnic background can be a factor as studies have discovered that this reaction tends to happen more in people with skin types 3, 4, and 5 (olive and darker skin) than it does in individuals with lighter skin. Additionally there is the opportunity that certain medication can increase the chance of paradoxical hypertrichosis if taken at the same time because the laser treatments. As you can tell, individuals with this disorder are so few and far between that it must be difficult to obtain a proper sampling.

Intensity which is too much can cause negative 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 unusual that 【激光脫毛】 can make your own hair re-grow thicker, this has been recognized to happen sometimes. If you are concerned, or if you know that the area you would like to have treated includes peach fuzz, perhaps a different method like electrolysis hair removal would be a better alternative to suit your needs. 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 cultivate back thicker. Each hair is individually treated so you do not run the risk of every other area of the epidermis receiving treatment other than where you want to be treated.
