You can find currently 2 known instances where there is a possibility that laser hair removal can make hair re-grow thicker and darker than it was before treatment. Please take into account that one is preventable while the other is so rare, the chances of it happening are very small.
The initial scenario can happen to anyone, though the majority of people that choose laser treatment may not be aware of this risk before treatment. In order to perform 【激光脫毛】, the technician will require that you shave the desired area a day or two just before your appointment. Your hair has to be as short as possible, yet still be visible, in order for the laser to operate to the full potential. Unfortunately, some areas that individuals wish to have lasered, (including the face and back), contain a combination of the dark coarse hairs that they want gone and “peach fuzz” (the extremely fine and colorless hairs that cover plenty of our body). When shaving this region when preparing for laser treatment, the peach fuzz that is present also gets shaved. With shaving, hairs have a tendency 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 and more hair is starting to grow after you have laser treatment.
The second instance is really a condition called “paradoxical hypertrichosis”. It really is a very rare reaction that may be experienced after laser hair removal treatment. As paradoxical hypertrichosis, (or postlaser hypertrichosis), is still a fairly new and really rare condition, there is not a lot of research done on the subject. It is difficult to find out what the precise cause of this phenomenon is. Some specialists advise that this unwanted hair regrowth could be caused by extremely low intensity laser or IPL treatments at levels that are too low to work and actually find yourself stimulating new hair growth in the hair bulb rather than destroying the hair bulb completely. Others claim that ethnic background might be a factor as reports have discovered that this reaction tends to happen more in people who have skin types 3, 4, and 5 (olive and darker skin) than it does in individuals with lighter skin. Additionally there is the chance that certain medication can increase the potential risk of paradoxical hypertrichosis if taken simultaneously since the laser treatments. As you can tell, sufferers of this problem are really few and far between that it must be difficult to get a proper sampling.
Whatever the suggested factors of paradoxical hypertrichosis, it is extremely important to discover a laser technician that is skilled and qualified 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 can be ineffective and also cause negative effects. Intensity which is too high can cause unwanted effects such as minor burns and skin discoloration. The ideal balance will safely ujuvnd effectively remove your unwanted hair to make your laser hair removal experience an optimistic one.
Even though it is rare that 【激光脫毛】 is likely to make the hair grow back thicker, it really has been known to happen in some cases. In case you are concerned, or once you learn that the area you need to have treated includes peach fuzz, maybe a different method like electrolysis hair removal might be a better alternative to suit your needs. Electrolysis does not require you to shave before treatment so you do not run the risk of shaving over any peach fuzz and causing it to cultivate back thicker. Each hair is individually treated so you may not run the chance of any other area of your skin receiving treatment other than where you need to be treated.
