Laser is being used for many years to remove unwanted hair on humans. This is highly successful in "Permanent Hair Removal". By the rules of FDA, manufacturers may not claim that laser hair removal is permanent unless it finds sufficient data to substantiate the results. Permanent reduction is possible but not the permanent removal of hair. But still there is more probability for the hair follicle to re-grow usually much lighter and finer. Laser hair removal often needs supplementary treatments.
Laser treatment uses energy in the form of light. This beam of energy is directed from the hand piece which is absorbed by the melanin in the hair follicle. The temperature will rise up to 70 degrees centigrade killing the follicle. This dead follicle will not encourage the growth of hair again. When excessive beam of energy is applied, it may result in burns causing blisters. It is suggested that people having dark hair and fair skin like the typical Irish complexion are best suited for the treatment. The melanin level should be as low as possible during the treatment. Hence the patients are advised not to go out in the hot sun prior to treatment.
People with white, grey hair have to be treated with care to avoid skin damage. The laser hair removal requires treatments at a much lower power level. There are more people heading for laser treatment for their problems because of the amazing advances in lasers combined with safer refractive surgical techniques in the past decade. But the laser treatments need well trained and professional operators. Hair grows in cycles and there are many factors influencing the growth like age, ethnicity, weight, hormonal changes, diet, medication etc. The treatment is aimed at destroying the hair that grows during this cycle.

Laser hair removal is accompanied by mild pain during its operation. The discomfort may range from a mild pain to a hectic sensation which can be unbearable. To avoid such discomfort, practitioners use a topical anesthetic cream which creates numbness around the area. Laser energy can enter an area that is wide open enough to accommodate even a single strand of hair. They produce light with specific wavelength to avoid deeper penetration and causing damage. It is important to know about the various laser treatments available in the clinic to find out the best treatment technique.
It is important to avoid large intake of beta-carotene as it might affect the entire hair removal process. Laser hair treatment is dependent on the amount of beta-carotene and independent of anything else. The laser treatment might prove expensive and therefore be aware of the price. They promise the stoppage of hair re-growth for a period of time. This is not a complete and permanent solution. There are chances for the growth of fairer or thinner hair.
