Four types of laser treatments form the Best Laser Hair Removal treatments available today. The argon method which was the first form of laser treatment has become extinct and has been replaced by newer and painless treatment methods. The four laser hair removal technologies recognized by the FDA for safe, effective treatments are the ruby laser, the alexandrite laser, the Nd: Yag laser and the diode laser. The Ruby laser hair removal treatment was the first effective form of laser hair treatment to hit the market. The Ruby laser has a powerful pulse and works well on dark coarse hairs on lighter skin. It can be used at a lower setting on darker skin. The output of the Ruby wavelength is 694mm and the wave is selectively absorbed by the targeted melanin without damaging surrounding skin cells.

While the Ruby is still used by some for effective laser hair removal, there are other technologies that are much more advanced and can get safe effective results both quickly and efficiently. An improvement on the Ruby is the Alexandrite laser. The Alexandrite laser is arguably the Best Laser Hair Removal system available today, is more versatile and can be customized according to the skin type and the amount of pigmentation within the hair follicles. It is useful for spot treatments depending on the hair's thickness and coarseness. The wavelength of the alexandrite instrument is 755mm and like the ruby the laser energy is selectively absorbed by melanin. It works fast and well on coarse, dark hair.

The Nd: Yag laser hair removal machine is very effective when treating coarse hair on darker or tanned skin tones. The wavelength of the Nd: Yag instrument is 1064 mm which allows the laser energy to pass safely through the outer layers of skin and down to the hair follicles below. The Diode laser hair removal method is arguably the most versatile of procedures because it can treat a large range of skin types effectively. The output can be altered according to the need of the patient. The wavelength of the instrument is 800-810 mm. These four laser technologies are the Best Laser Hair Removal systems available and each patient will get optimal results by undergoing treatments with the laser most geared towards their individual hair color and skin tone.
