Who is fit for laser hair removal?
Laser hair removal works best for patients with dark hair. Because melanin pigment (dark pigment) is the main driver of hair follicles, the skin absorbs less laser energy and the hair follicle absorbs more. Tanned skin also “removes” laser energy as it passes through the skin to the hair follicle. Because hair pigment is the driver of laser energy, gray hair (which lacks pigment) can not effectively be treated with laser or any other light device.
How Many Laser Hair Removal Treatments Do I Need?
The number of treatments required to obtain optimum long-term results depends on the area to be treated, hair density and growth cycle. Hair grows in cycles and many factors influence its growth. Age, ethnicity, weight, hormones, diet, medication and metabolism play an important role in hair location, thickness and endurance. Laser energy is most effective in the hair growth stage, also known as the anagen phase of the cycle. As latent hair, or telogen, is activated on average 6 weeks after treatment, the growth of new hair will be observed. Multiple laser treatments are required for best results.
