You will find currently 2 known instances where you will find a possibility that hair laser removal could 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 first scenario can occur to anyone, though the majority of people that choose laser treatment may not be mindful of this risk before treatment. So that you can perform 【激光脫毛】, the technician will need you to shave the required area a day or two prior to your appointment. Your hair must be as short as is possible, but still be visible, in order for the laser to function to its full potential. Unfortunately, some areas that folks wish to have lasered, (such as the face and back), contain a mixture of the dark coarse hairs which they want gone and “peach fuzz” (the extremely fine and colorless hairs that cover plenty of the body). When shaving this region when preparing for laser treatment, the peach fuzz which is present also gets shaved. With shaving, hairs have a tendency to re-grow thicker, darker, and faster with every shave. The fine hairs that were once unnoticeable may now start to appear darker upon return, which could make the illusion that more hair is starting out grow after having laser treatment.
The next instance is a medical condition called “paradoxical hypertrichosis”. This is a very rare reaction that may be experienced after laser hair removal treatment. As paradoxical hypertrichosis, (or postlaser hypertrichosis), is still a relatively new and extremely rare condition, there has not been significant amounts of research done on the subject. It is not easy to find out what the precise reason for this phenomenon is. Some specialists advise that this unwanted the growth of hair may be brought on by extremely low intensity laser or IPL treatments at levels which are too low to be effective and also end up stimulating new hair regrowth within the hair bulb rather than destroying your hair bulb completely. Others claim that ethnic background can be a factor as research has learned that this reaction is likely to happen more in individuals with skin types 3, 4, and 5 (olive and darker skin) than it does in people with lighter skin. Additionally there is the possibility that certain medication can increase the chance of paradoxical hypertrichosis if taken simultaneously as the laser treatments. As you can see, people with this condition are extremely few and far between that it is difficult to get a proper sampling.
Whatever the suggested factors of paradoxical hypertrichosis, it is very important to discover a laser technician that is certainly skilled and qualified to perform your treatments. They must be knowledgeable enough to determine the correct laser intensity setting for the particular hair and skin attributes. Too low could be ineffective and actually cause adverse effects. Intensity that is too high can cause side effects including minor burns and skin discoloration. An ideal balance will safely ujuvnd effectively remove your unwanted hair and make your hair laser removal experience a positive one.
Though it may be very rare that 【激光脫毛】 is likely to make your hair grow back thicker, it has been recognized to happen in some instances. In case you are concerned, or once you learn the 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 prior to treatment so you may not run the potential risk of shaving over any peach fuzz and causing it to grow back thicker. Each hair is individually treated so you do not run the chance of every other area of your skin receiving treatment other than where you would like to be treated.
