There are currently 2 known instances where there exists a possibility that hair laser removal will make hair re-grow 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 most people that opt for laser treatment will not be conscious of this risk before treatment. So that you can perform 【激光脫毛】, the technician will require that you shave the required area a couple of days prior to your appointment. The hair must be as short as possible, yet still be visible, in order for the laser to work to its full potential. Unfortunately, some areas that folks wish to have lasered, (like 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 lots of our body). When shaving this region when preparing for laser treatment, the peach fuzz which is present also gets shaved. With shaving, hairs often 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 may make the illusion more and more hair is beginning to grow after having laser treatment.
The second instance is really a condition called “paradoxical hypertrichosis”. It is a rare reaction which can be experienced after hair laser removal treatment. As paradoxical hypertrichosis, (or postlaser hypertrichosis), remains a somewhat new and really rare condition, there has not been a lot of research done on the subject. It is difficult to find out what the precise reason for this phenomenon is. Some specialists advise that this unwanted hair growth may be brought on 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 might be a factor as studies have discovered that this reaction is likely to happen more in individuals with kinds of skin 3, 4, and 5 (olive and darker skin) than it will in people who have lighter skin. Addititionally there is the chance that particular medication can increase the risk of paradoxical hypertrichosis if taken concurrently since the laser treatments. As you can tell, people with this problem are really few and far between that it is difficult to acquire a proper sampling.
No matter the suggested factors of paradoxical hypertrichosis, it is rather important to locate a laser technician that is certainly skilled and qualified to perform your treatments. They should be knowledgeable enough to ascertain the correct laser intensity setting for the particular hair and skin attributes. Too low may be ineffective and cause side effects. Intensity which is too high may cause negative effects like minor burns and skin discoloration. An ideal balance will safely ujuvnd effectively remove your unwanted hair to make your laser hair removal experience a good one.
Even though it is rare that 【激光脫毛】 will make your hair re-grow thicker, this has been proven to happen in some instances. In case 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 might be a better alternative for you. Electrolysis will not require you to shave just before treatment so you may 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 potential risk of some other area of your skin receiving treatment apart from where you need to be treated.
