Spot size is defined by the diameter of the laser beam; large spots allow deliverance of more effective fluences in the dermis.11. The period in which the hair is most susceptible to laser light is the anagen, or active growth phase.8,9 The duration of the cycle varies on different parts of the body; consequently, more than one laser session is usually needed because follicles on different parts of the body are in different phases of growth.

As emphasized before, we called all patients in for retouch sessions 2 weeks after each main session was performed. Because the mechanism of action, physical and chemical effects of laser energy, and statistical results of hair follicle removal had been previously published, we sought in this paper to share our practical experience and method of applying the technique, rather than to again demonstrate its effectiveness.14–16. The laser also eliminates brown pigmentation, age spots, reduces fine lines, and rejuvenates the skin.

Paradoxical hair growth (hypertrichosis) refers to the stimulation of hair regrowth caused by a laser treatment. Intense pulsed light (IPL) is also available, while not truly a laser as it uses multiple wavelengths of light to provide energy (400 to 1200 nm). We usually treat patients on the Yag laser in the 50 – 80 j/cm2 range with the Sciton Profile.

Our study is based on the retrospective data analysis and evaluation of 322 patients, all of whom received alexandrite laser hair removal in more than 3 sessions between January 2000 and December 2002. This is because – at any one point in time – each of your (hundreds of thousands of) hair follicles will be in one of several stages of the hair growth “cycle.” (Appropriate) lasers only treat hair follicles that happen to be in their “active” growth stage of the cycle at the time of treatment. This study was presented as a poster at the 6th Panhellenic Plastic, Reconstructive and Aesthetic Surgery Congress in Athens, Greece, October 1–5, 2003.

Laser hair removal can take 5 to 10 treatments before you see full results.
