As one of the leading laser hair removal providers in the area, Dr. Mark X. Lowney receives a lot of inquiries about the treatment. One of the questions that arise frequently is whether hair grows back after treatment, so Dr. Lowney decided to devote a blog post to the answer and explanation.
RESULTS DEPEND ON THE NUMBER OF TREATMENTS
It is important to understand that hair grows in different stages, and treatment only affects hair in the active growth phase. Certain hair follicles may be dormant during treatment and enter the anagen (i.e., active growth) phase a few weeks later. This is why Dr. Lowney and our team recommend a series of treatments, spaced several weeks apart, to see the desired results. According to the American Academy of Dermatology, each treatment session causes a reduction of between 10 and 25 percent in hair growth.
If it is recommended that you have a series of five treatments on your legs or arms, and you only finish one or two sessions, it is reasonable to expect to see hair regrowth. Also, if you go to another facility with a less-powerful laser and an inexperienced technician performing the treatment, you might start to see hair growing in the treated area.
On the other hand, if you had laser hair removal supervised by a physician at a credible facility, and you completed the entire series of appointments recommended by the doctor, you should see a dramatic reduction in hair in the treated area. You can reasonably assume that most of the hair will be gone and there should be very little growth (think: sparse hairs, if any).
OTHER FACTORS AT PLAY
If you have completed the recommended number of treatments but notice hair growing back in the treated area, there may be other factors at play. For example, you may have an underlying hormonal problem that is causing hair regrowth. This is an issue you should bring up to Dr. Lowney or your primary care physician. You might need to have bloodwork done to check your hormone levels or another test to rule out another type of medical condition.
