Laser hair reduction is a noninvasive method of removal of unwanted hair. It can be a good option for those with excess body hair who are looking for a way to effectively reduce or remove hair from various body areas.
Diode Laser hair removal works by targeting the melanin pigment in the hair follicles. The heat from the laser light transmits from hair shaft to the the bulge area which is the growth centre of the hair.
The pigment in the hair attracts the laser, so darker hair absorbs the laser more effectively, which is why people with dark hair and light skin are ideal candidates for laser hair removal. Patients with dark skin typically need to be treated with a special type of laser that detects the hair against their skin.
Those with light hair are less prone for laser effect and they are also less likely to experience drastic results as the laser doesn’t focus well on non pigmented hair. Laser hair removal is not effective on blonde, gray, or white hairs.
The time depends upon the size of the area you are concerned. The bigger the areaﾠyou would like to be treated, the longer the procedure it takes. Small areas likeﾠupper lip, can take as little as a couple of minutes while larger areas such as theﾠchest can take an hour or more. Whole body laser may take as longer as 3-4 hours.
Avoid sunlight exposure as much as possible before the procedure, and always useﾠa sunscreen. The tanned skin makes the contrast between hair and skin less visibleﾠand reduces the efficiency of the treatment.ﾠAvoid shaving the area 3-4 days before the procedure as recognition of the hairﾠshaft by the technician helps in targeting as many hair follicles as possible.ﾠAvoid waxing and other depilatory methods as they pull the hair out of the follicleﾠand leaves no pigmented to be targeted.
The number of laser sessions depend upon the thickness of hair. For normal peopleﾠ5-6 sessions will be sufficient, but women with coarse hair due to hormonal issues,ﾠmay take 10-12 sessions to achieve the desired result. Dark skin makes the contrastﾠless visible and may result in more treatment sessions. People with light skin andﾠdark hair, may get away with fewer sessions.
Depending upon the growth cycle, laser should be repeated at 4-6 weeks interval.ﾠDiode laser and Nd:Yag laser are the commonest and safest lasers used for hairﾠremoval. They all work by targeting the hair pigment also known as melanin. Thatﾠis why laser gives best results with dark, thick and coarse hair and not with fineﾠhair. This melanin pigment is most abundant in the early growth phase (anaphase)ﾠof the hair. Hence, this is the time one should come for a repeat session.
With each session of laser, you may expect 10-20 percent of hair reduction. Itﾠtypically takes between three and eight sessions for permanent hair loss. After aﾠdetailed examination of your area of concern, we can give you a better idea of howﾠmany treatment sessions you may need. Also, you will likely need a touch-upﾠsession yearly to maintain effect, if the need be.
Swelling, redness, temporary discomfort are the common side effects after laser.ﾠRarely, it may cause burns, scars, blisters, infections, permanent changes in skinﾠcolor if performed by untrained people using non medical lasers. So carefullyﾠchoosing a skilled medical professional (plastic surgeon or dermatologist) canﾠgreatly reduce these risks.
Yes, laser hair reduction is permanent and the results depend upon the quality andﾠcolour of hair and skin and also upon some predisposing factors like hormonalﾠissues as in PCOD.
The recovery time after the procedure is minimal and most patients can return to work as normal directly after. Just as wearing sunscreen before the procedure is important, so is continuing to wear it after the procedure. This will help prevent further irritation.
