Laser Hair Removal

 Laser Hair Removal

 

Hair waxing is a fairly efficient means of removing your body hair temporarily. Electrolysis of hair is one of the safest technologies to obliterate the unwanted hair from the body. These are convenient and comfortable methods of hair removal, with their share of problems and hazards. However, one more hair removal technique deserves to be discussed. This is the much lauded laser hair removal technology. Hair removal by laser is one of the safest and most durable means of removing hair. It has been approved almost unanimously by scientists and researchers. Like all human inventions, laser hair removal has its own virtues and flaws. A better understanding of this technique can be of value to many people. Let’s check out laser hair removal and its salient features.

 

How Is It Done?

The technique of hair removal, through the means of laser, is quite complicated. Laser hair removal involves the use of a particular density of light and pulse. This particular adjustment is aimed to direct the action of laser’s light and radiation on a particular object. Ever since its evolution, laser hair removal has always concentrated on the attack on the hair follicles and cuticles. The basic objective behind laser hair removal is to hamper the functions of the follicles of unwanted hair. This is what the laser does. It absorbs the hair pigments and attacks the tissue for the growth of new hair. Laser treatments have been valued for their quick processes. It should be kept in mind that laser hair removal does not remove hair completely or permanently. It will remove hair for a long time. However, unlike electrolysis, the hair will not go permanently.

 

Some More Facts

It took quite late for the people to actually make use of the laser technology in removing the unwanted hair. The scientists had spent nearly two decades in experimenting with laser hair removal, before it became commercially viable. Many scientists have approved of the technology’s efficiency and durability. However, despite the success rate, flaws and problems have arisen out of the use of laser hair removal. We will look at the pitfalls of laser hair removal in more detail later. For most of time, the side effects of laser hair removal have been few and mild, compared to those of other conventional hair removal techniques, such as waxing and bleaching.

It should be said that the different wavelengths of laser light are also determinants of how good a laser hair removal can be. Different wavelengths and densities offer differing results on hair. For instance, the Ruby laser and Alexandrite laser are best and most effective for those, who have pale and light colored skin. The pulse diode array laser, with a wavelength of 810 nanometers, can suit both pale and normal colored skin. The best laser for varied hair removal treatments is the YAG laser. This has a wavelength of 1064 nanometers and can work best for both dark and pale skin. Apart from this, the fluency, laser beam width and other related factors play an important part in disabling the hair follicles to prevent and restrict the new growth of unwanted hair. The heat of the laser beams should also be sufficient to perform this function.

 

Sessions of Hair Removal

The usual laser hair removal can take place in seven sessions. However, it would be wrong to assume that all treatments will last for the same duration. Plenty of factors decide how long will it take for the treatment of laser to complete. One important factor is the area under treatment. If it is one of sensitive skin, then the laser treatments can take a lot of time. There are other similar factors, which affect the treatment. Light skin with dark hair often takes little time to be treated. However, the same would not apply to dark skin. It should be also remembered that most lasers do not work well on light colored hair. Therefore, laser hair removal would work best for dark hair and light, fair skin. It is also generally recommended to take the sessions of treatments with regular intervals. The nature of the intervals also depends on some of the above mentioned factors.

 

The Problems of Laser Hair Removal

While being safer and almost painless, laser hair removal is not exactly a flawless means of removing unwanted hair. Many of the laser hair removal’s problems are associated with the disturbances and inconsistencies in the settings of the laser beams. Too much heat can cause a severe discoloration or burning of the skin. The great intensity of laser can also destroy the creation of pigments and colors in hair and skin. This may result in creation of white spots and patches on the skin. There could be also conditions of acne or severe swelling of the hair follicles and cuticles.

Some problems and adversities can occur shortly after laser hair removal is done. Itching and inflammation of the skin are some of the most frequent consequences of laser hair removal. These can occur as a side effect of treatment of hair by the particular wavelength of laser beams. Also, some effects occur before the treatments. Usually, before the hair removal begins, a numbing cream is applied on the skin. Sometimes, the cream is used inappropriately. This can cause many skin diseases and even can be fatal.
