Effectiveness of Laser

The lasers target area of activity is the stem cell group, where the cells multiply very fast in the growing stage (anagen) of the hair production cycle. Hence, laser therapy is most effective in the anagen stage. Though hair production is gradually slowed down after each laser session, permanent hair removal is not possible. Lasers actually ensure a temporary complete hair removal. Generally, there is re-growth after 6 months (though it is sparser than the initial growth) and one must undergo additional therapy.

Research has also shown that despite the laser type employed, significant clinical result is possible after at least 1 month of the second laser session. More noticeable hair reduction is generally occurs 6 months after the third and last laser application.

Effectiveness of the laser depends on the kind of laser used and the patient’s skin biology. Generally, laser hair removal works best on fairer cases with dark-pigmented hair. Estimates suggest that around 80 percent of cases benefit from laser hair removal, though some require multiple sessions.
