Permanent Hair Removal

Permanent hair removal procedures verses other methods….what is permanent when it comes to hair removal?  Well, when it comes to advertising, permanent hair removal doesn’t mean it lasts forever.  Other products that tote that they are permanent are a permanent wave and a permanent magic marker. But are they?  Assessing new hair removal systems or procedures that manufacturers claim to be permanent it is very unlikely they will stop hair from returning over time.  Look at the advertising campaigns such as one manufacturer that claims their permanent hair removal results last 9 weeks…thats just 9 weeks, other alternative methods like waxing can last that long.  What is hairfacts definition of permanent when we look at hair removal treatments?  Without having to use another treatment or another product your hair should not return for a year.  Now this doesn’t seem like it is long enough to be defined as true permanence, but most people are satisfied with one procedure a year.  The only method that is clinically proven to permanently remove hair is electrolysis as some lasers or flash lamp achieve only permanent hair reduction.  Because of all the different distinctions of permanent hair removal I have divided them into three different categories; long-term hair removal, semi-permanent hair removal and hair reduction.

Long-term hair removal as defined is at least 6 months from the final treatment without using another method or product.  Semi-permanent hair removal which usually describes a laser treatment results lasts a few weeks.  As permanent hair removal destroys the hair follicle’s ability to regenerate and grow, hair reduction by lasers reduce the size of hairs especially coarse dark hair and lighten their color, the reduction appears to be permanent. 

If you are seeking permanent hair removal and want to spare the surrounding tissue from damage (which is hard to do) electrolysis will destroy the follicles by inserting a thin metal probe into the hair follicle. Proper insertion will not puncture the skin and should be done by a qualified practitioner as self-treatment is not recommended. If done wrong can be very painful, partial or full regrowth of hair and infections, Electrolysis has over 125 years of clinically proven safety and effectiveness. Up to 10% of the people treated were not satisfied with the results.  Treatment can be expensive, but can be 100% permanent.  

Lasers use a light at a specified wavelength that causes thermal or mechanical damage to a hair follicle while sparing the surrounding tissue.  Some customers experience long-lasting hair removal or permanent hair reduction.  If hair returns it can come back finer in texture and/or lighter in color. Best used on dark hair, generally not as effective on gray, red or blonde hair.  Not recommended on darker skin tones or those that tan.    It is generally safe to perform, but if improperly performed can cause burns, lesions, skin discoloration that lasts several months and patchy regrowth.  Can be expensive and more than one treatment may be recommended.  Treatments vary since each individual's hair growth occurs at different rates. On the average, treatments are usually spaced about 4-6 weeks for facial areas, 6-8 weeks for back and bikini areas, and 10-12 weeks for legs.

Flashlamp like laser therapy uses a full spectrum (non-coherent) light and low-range infrared radiation is filtered to allow a specified range of wavelengths to destroy hair follicles with long-lasting hair removal or permanent hair reduction results.  Result data is the same as laser results.


Other lasting hair inhibitions that require continued use are oral prescription medications and topical preparation, Vaniqa. Vaniqa (pronounced “VAN-i-ka”) is a brand name prescription cream applied to the skin for the reduction of unwanted facial hair in women ages 12 and older. Your health insurance may not cover Vaniqa.  In clinical trials 58% of the women that used it had improvement, while 42% had no improvement. This medication is not a depilatory but acts as a hair retardant.  You may have to shave and/or pluck while you take Vaniqa, as full results take up to two months. If you stop taking Vaniqa your hair may grow back within two months.  Vaniqa should not be used by men as it has not been tested on males, by women that are pregnant or nursing, females under the age of 12, if you have acne or broken skin or by eyes, nose, mouth or vagina.


Restricted methods include x-ray which is banned in the United States and photodynamic therapy which is experimental.  Other methods that get rid of hair but are not permanent are; electric tweezers, transdermal electrolysis, transcutaneous hair removal, photoepilators, microwaves, dietary supplements and nonprescription topical preparations.
