Does Missing a Session of Laser Hair Removal Mean I Have to Start From the Beginning?

For optimal results in the fewest number of treatments, laser hair removal should be done by a trained dermatologist or directly under their supervision, and should be done at 4 week intervals. The hair should be present but short and the best candidates are those with darker hair and lighter skin. You should not have the treatment if you have a suntan or have had recent sun exposure in the area you're planning to treat.

Lasers create a beam of highly concentrated light that penetrates deep into the skin where it delivers a controlled amount of therapeutic heat that is absorbed by the pigment located in the hair follicles. The laser is only effective when the hair follicle is in its active growth phase. The laser pulses for a fraction of a second, just long enough to destroy numerous follicles at a time and leaves the surrounding skin unaffected. Once these follicles are destroyed, the hair should not regrow even if you miss your next treatment session. It sounds as if your treatments are not as effective as they should be if you are not seeing any improvement by now.
