Laser technology for hair removal was introduced in mid-1990s when it was successfully experimented by a group of dermatologists. Earliest records of commercial advertisements about laser technology includes articles by Massachusetts General Hospital authors, that were published in 1998. Within a period of one decade, laser technology has crawled its way into dermatology clinics around the globe, where it is readily recommended and practised for hair removal.
Laser technology used scientific principle of selective photo-thermolysis to burn hair growing follicles. This technology uses light wavelength and pulse to have optimum coverage on a targeted skin patch. It also helps to ensure precision to avoid effect on surrounding skin tissues.
There is a great debate associated with laser technology. It is about the authenticity of the claim that laser technology has everlasting and permanent results in favor of hair removal. It this really true or not? Should I spend a large amount of money all in vain? Will I get permanent rid of my public hair? These questions are generally asked by consumers. Many of them are pretty insecure to exploit the technology due to similar reasons.
So is it really effective in permanent hair removal?
Laser technology incorporates highly concentrated light beam which results in creation of therapeutic heat. There are various factors that influence permanent hair loss, like skin color, hair color, hair thickness, density and concentration strength of laser beam. According to statistics, permanent hair loss is possible with optimal parameters only in 15-20 out of 100 consumers.
Permanent reduction requires a lot of periodic maintenance, which is only possible with multiple laser courses. Laser technology mostly slows down hair growth, but doesn’t guarantee permanent removal of small colourless hair. Skin tone dramatically affects permanent hair removal. The more the heat absorption by hair follicles, the more effective the hair removal. Heat absorption is more effective on darker tones because darker hair have large melanin pigment. As the laser beam targets melanin, people with dark thick hair have more success with laser treatment in comparison to people with lighter tones and brown or golden hair.
An important factor to be considered while opting for laser treatment are its side-effects. Concentrated light beam can cause excessive burning in hair follicles leading to swelling or itching, especially for people with sensitive skins. Also, people with loose skin may suffer from infection, allergy, blistering, dark patches and skin discolouration.
For many individuals insecure of their excessive hair, laser hair removal has been life altering. On the other hand, many find the whole process extremely uncomfortable. Many people have low threshold for pain and are not able to endure burning sensation. Still, it is way better option than electrolysis because it involves needle probes. Laser technology only ensures permanent hair ‘reduction’, in comparison to electrolysis that has been approved internationally for permanent hair ‘removal.
These days, hair removal through laser beam can also be done in home. Hair removal machines have been invented, that are as effective as any laser course done in a dermatologist’s clinic.
