Wendy Lou; Adelle Quintana; Roy Geronemus; Melanie Goldman. Prospective Study of Hair Reduction by Diode Laser (800 nm) with Long-Term Follow-Up. Derm Surg. 2000; 26:428-432. Objective: The purpose of this study was to determine the safety and long-term efficacy of the 800 nm, pulsed diode laser at reducing hair count. Methods: Fifty volunteers, primarily Fitzpatrick skin types II and III, with dark brown or black hair, were treated with a diode laser (800 nm, 10-40 J/cm2, 5-30 msec, 9 mm x 9 mm, 5oC chilled hand piece). Each subject had eight treatment sites at varying fluences and pulse durations, as well as a varying number of treatments and pulses. Hair counts were obtained at each site at baseline, 1, 3, 6, 9, and an average of 20 months after treatment. Results: After one treatment, hair regrowths ranged from 22 to 31% at the 1-month follow-up visit, then remained stable between 65 and 75% from the 3-month to the averaged 20-month follow-up. After two treatments there were relatively longer growth delays, with hair regrowths plateauing beginning at 6 months after treatment and ranging from 47 to 66% for the remainder of the follow-up evaluations. Side effects were limited to pigmentary changes, transient in subjects with skin types II and III. Conclusions: This 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.

Laser Hair Removal
Remove Unwanted Hair
Now there is a BETTER SOLUTION for removing unwanted hair.
You may be surprised to learn that virtually your entire body is covered with hair. Because most of this hair is fine and pale, it usually isn’t visible to the naked eye.
But, when darker, coarser hair appears in places which make you uncomfortable, it may be time to consider hair removal with LightSheer DUET.
Understanding Hair Removal
In the past, remedies for unwanted hair included plucking, shaving, waxing, electrolysis or chemical depilatories. Some are painful. Some are messy, and all are only temporary.
Laser hair removal is a more effective solution.
The High Speed LightSheer DUET uses state-of-the-art diode lasers with vacuum-assist technology to remove unwanted hair and with greater speed and comfort than other methods.
