Darker Skins Are Great Candidates for Laser
Darker skin types can benefit equally from laser, especially when the hair is coarse. In some cases, Fitzpatrick type IV skin with coarse hair may achieve excellent results in fewer than the typical 6 to 8 treatments.
The combination of light skin and dark hair is ideal because laser targets pigment. Dark hair absorbs more energy, making treatment more effective. However, laser can also be attracted to pigment in the skin, which is why lighter skin tolerates higher treatment levels and often responds more quickly.
For darker skin types with significant coarse hair, starting with laser before moving to electrolysis is often recommended.
Is it safe? Hyperpigmentation is the skin’s natural response to injury, and laser treatment creates controlled heat within the follicle. Fitzpatrick type IV or V skin may occasionally develop temporary darkened areas, sometimes appearing speckled or mottled.
Finer hair responds well to electrolysis with minimal after-effects, while coarser hair may respond more slowly and can temporarily darken due to higher treatment levels. Laser, by contrast, is most effective on coarse hair.
Can laser stimulate hair growth? Studies show that “paradoxical stimulation” can occur, but it is very rare. Similar concerns exist with electrolysis. In practice, other factors such as stress, hormonal changes, weight fluctuations, medications, waxing, and tweezing are far more common causes of increased hair growth.
If there is concern about stimulation, treatments can be spaced further apart, and shaving before treatment should be avoided.
