Laser Therapy for Unwanted Hair
Getting rid of unwanted hair is no longer a painful or unsatisfactory process. Using technologically advanced laser hair removal processes, larger areas may be treated using lasers than with electrolysis, waxing or tweezing. It combines the speed of shaving with the lasting results promised by electrolysis. Laser hair removal is effective on almost any area of the body where smoother hair-free skin is desired. Several laser hair-removal systems – including the diode laser, the long-pulsed alexandrite and Nd:YAG lasers and the IPL – are being used successfully with long-lasting results.
How is laser hair removal different from electrolysis?
Electrolysis delivers an electric shock via a needle to burn the follicle and retard hair growth. Laser hair removal uses wavelengths of light that are specifically absorbed by the pigment in hair follicle structures. Most patients who have had both procedures say that laser hair removal is less painful, faster and more convenient, and they love the results.
What are the laser treatments like?
During laser hair removal, the area to be treated is scanned with the laser. The laser energy passes through the skin and is absorbed by the pigment in the hair follicle.
In a fraction of a second, all of the treated hair follicles are “zapped” and hence disabled. Treatments can last from a few minutes to a few hours depending on the overall size of the area being treated.
You can return to your normal activities immediately. Sun protection, especially the use of sunscreen, is recommended on any treated areas exposed to the sun.
How many treatments will I need?
The number of treatments you may require for optimal long-term benefits depends on the area you wish to have treated, the hair density and your hair’s growth cycle. Your hair grows in cycles, and many factors influence its growth. Age, ethnicity, weight, hormones, diet, medication and metabolism all play a part in your hair’s location, thickness and resilience.
The laser slows the growing capacity of follicles in the growth cycle at the time of the treatment. Since other hair follicles later enter their growth cycle after your treatment, multiple treatments are required to deliver optimal results. Treatment results will vary from patient to patient depending mostly on hair cycle factors, hair color, and number of treatment sessions. Multiple treatments will usually lead to a permanent reduction of hair in the areas treated.
