Laserpro technology has been shown to be very effective by a number of different studies by some of the worlds leading educational and research institutions.

Harvard Medical School –Study of diode Laser for Hair Reduction on all Skin Types.
In a study on forty subjects, 25 female and 15 males with coarse, dark hair on their thigh and backs, it was concluded that an 800 nm diode laser provides for effective, long term hair reduction of medium to coarse pigmented hair, even in some darker-skinned patients. Both short term hair growth delay and permanent hair reduction was observed. In addition, when hair regrowth did occur, the hair was thinner and lighter.

Jinnah Medical College, Lahore, Pakistan - Laser Hair Removal with an 800 nm Diode
In a retrospective study of 1000 women with Fitzpatric Skin Types II and VI, it was estimated that for 500 women treated on their entire face and neck, apparent hair reduction was in the 70% to 80% range after five to six treatments. In other areas hair reduction was higher ranging from 80% to 95% with the women achieving satisfactory results within four or five treatments.

Harvard Medical School / Laser Center of New York - Effective, Permanent Hair Reduction Using a Diode Laser.
Study was completed on 92 patients treated at two seperate facilities, with 45 males and 47 females of varying hair colours and skin types. Treatments were made at 0, 1, 3, 6 and 9 months.
It was concluded that 89% of patients achieved significant permanent hair reduction in this large, long-term, blind, controlled and quantitative study. Many patients had nearly complete, permaent hair reduction after two treatments. Regrowing hair was typically thinner and lighter in colour, adding to the cosmetic benefit.

Reported on a multicenter clinical trial study involving 150 patients. The study involved six treatments given 1 - 2 months apart with patients being followed for at least six months after the last treatment.
It was concluded 93% of females and 80% of males had significant permanent hair reduction.

 In this study, hair shaft diameter and optical transmission (700 nm) were measured before and after ruby (694 nm) and diode (800 nm) laser irradiation on 47 and 41 patients respectively. "Responders" were defined as subjects with significant long-term hair loss. In ruby laser responders (34/47), regrowing hairs were significantly both thinner (decreased diameter) and lighter (increased transmission). After diode laser treatment, 38 of the 41 subjects were responders and regrowing hairs were both thinner and lighter. These results show that laser treatments can affect structural recovery (size of hair), follicular pigmentation (hair absorption coefficient), or both and that regrowth of thinner hair (decreased shaft diameter) occurs in conjunction with actual loss of hair.
 It was concluded that Laser-induced reduction in hair diameter and/or pigmentation are both long-term responses which provide cosmetic benefits in addition to actual hair loss.

Study was to determine the safety and long-term effectiveness of the 800 nm, pulsed diode laser at reducing hair count. Study was conducted on fifty volunteers, primarily Fitzpatrick skin types II and III, with dark brown or black hair. Each subject had eight treatment sites at varying fluences and pulse durations, as well as a varying number of treatments and pulses.
Conclusion: The 800 nm diode laser with a chilled sapphire tip and variable pulse duration is safe and effective for long-term hair reduction in individuals with skin types II and III.

Objective of study was to evaluate the effectiveness of a diode laser in the treatment of pseudofolliculitis barbae on ten patients with skin phototypes I to IV. Three treatments were performed at 6- to 8-week intervals, and subjects underwent evaluation for improvement in the pseudofolliculitis and the degree of hair reduction. Complete hair-growth delays of 3 to 8 weeks' duration were produced, and a decrease in hair density of greater than 50% was noted in all subjects 6 to 8 weeks after the last laser treatment. All patients exhibited greater than 50% improvement in the signs of pseudofolliculitis.
