Laser hair reduction versus laser hair removal. What can be achieved? A caller asked me recently.

Laser hair reduction is getting rid of 70 to 90 percent unwanted hair. Laser hair removal means getting rid of 100% hair.

Medically,laser hair reduction is possible medically. Laser hair removal cannot be achieved. In case, one claim to deliver, laser hair removal, understand it’s a lie. Till date, best of the lasers can deliver only laser hair reduction. 70 to 90 percent hair gets killed. Whatever hair remains is reduced to thin villous hair. Their original thickness is gone. Also, when remaining hair is shaved, they grow back after a delayed time. If they used to grow back after a week’s time post shaving, they would now grow after three months. They are very soft to touch. Thus, laser hair reduction is good enough target to be achieved.

Laser hair removal till date is has not been achieved. Don’t fall prey of the centers claiming the same.

A US FDA approved Diode laser can deliver laser hair reduction. It takes around 6 to 8 sessions. Sessions are done at 4 to 8 weeks interval. Each session of full body takes around 2 hours. Smaller areas take lesser time. Dermatologist should be supervising each session. Slight pin prick sensation can be felt during laser shots. It can be tolerated comfortably.  Person can resume normal life immediately after the session. Laser hair reduction has no long term side effects.

With advent of technology, lasers have undergone a huge transformation. Newer  technology replaces the old one almost every five years. Laser hair reduction is no exception.


IPL: Very first we had IPL –Intense pulse light for laser hair reduction. It’s basically broad band light and not specific to kill hair. Thus, it was least effective.

Nd :Yag Long pulse laser: Better than IPL since it was more specifically targeting hair. Drawback was energy needed to kill hair would make the whole procedure very painful.

Diode: The best so far. Diode is specific for targeting hair, and is suitable for all skin colors. Also it has proved it’s efficacy in reducing hair safely and for long term over more than two decades.

Alexendride: Technically superior to diode in giving results, but is too expensive thus didn’t get much acceptance in market. Also it’s a very strong laser, so if done right, give good results but in case gone wrong, chances of burns are much higher.

Triple wavelength laser: It emits all the three wavelengths: ND:YAG, diode and alexandrite in single shot . Technically sounds to be the best. Fault lies in the fact that one third is wasted in less effective Nd: Yag. The alexandrite put in this triple wavelength laser is not of the right pulse width required to kill hair. Thus, plain alexendride is better than the triple wavelength laser.

So now we know that diode is the best laser.

Apart from the technology it’s the quality that matters.

A cheap diode laser won’t give any results. Only a high quality US FDA approved laser would give the desired results. A photograph can be clicked with a cheap smart phone camera and also with a high quality DSR camera. Quality and the results of the photograph is not going to be the same. Same stands for laser. Thus always check for the laser quality before going for laser.


Just ask for the brand name of the laser and google it out. You will find out the quality and technology . In case the clinic refuses to divulge the details , you already got your answer.

Some people don’t get results after laser hair reduction. Reasons are summed up as below:


  1. QUALITY OF LASER MATTERS: One can click a photograph with 2000 Rs. Smart phone also and a 2 lakhs Rs. DSLR camera also. The results and quality of photograph is not going to be the same. Similarly lasers have quality. A cheap laser won’t give results. Only and only USFDA approved good quality laser would give results. That’s because only it has the power to deliver the voltage and energy required to actually get results.

Now how do you find out what quality laser is a particular clinic using. Just ask the brand name of the laser and Google it out. In case the clinic refuses to tell the brand name, you got your answer. A clinic using good quality laser would certainly let you know the brand  name .

  1. ONLY RIGHT ENERGY GIVES RESULTS: The interplay of various laser parameters like energy, spot size, pulse duration etc. decides the results. A lay man when given even the best of the camera in hand just knows how to says cheese and click. Only a professional photographer knows how to use the camera and click the best shot. So get it done by a dermatologist run clinic where everything is supervised by a doctor and not by businessman run clinics, where technicians are handling everything. right energy delivered give results , low energy gives no results , high energy may leads to side effects.

So choose your skin laser clinic wisely.

Summary: Right energy levels delivered under dermatologist’s supervision by a US FDA approved laser and not by cheap laser is the key to get best of the results with laser hair reduction.

Best clinic for laser Hair reduction follows the given criteria:

  1. A qualified dermatologist should do laser hair reduction : A dentist or homeopathic doctor should not be doing it. A dermatologist has in depth knowledge of laser treatments. Other specialists are not expert in dermatology.
  2. US – FDA approved lasers are recommended: Market is full of Chinese lasers. Stay away from them. Chinese lasers compared to US FDA approved lasers, is like comparing picture taken from cheap smart phone with a DSRL camera.  A smart phone may cost 2000 INR whereas a DSLR camera is worth 10 times of that. Quality of the photograph is not going to be the same. This analogy can be extended to laser treatment. Also, bad quality laser have more side effects.                                            
  3. Doctor’s supervision is foremost. Dermatologist must be present during laser treatments. In lot of commercial laser centers, non-medicos are doing the procedures.  As a surgeon  performs surgery,  dermatologist should perform laser treatments, not anyone else.
  4. Avoid laser on soft hair. Soft hair are  hardly visible after bleach.Thus,  Don’t do laser there. Thick hair are ideal for laser hair reduction.
  5. Maintenance sessions are important: Annual maintenance sessions are required after the desired results are achieved. This will ensure results are permanent. Skin would try to regrow the killed hair roots. Its important to kill whatever hair  skin has regrown by having once a year maintenance sessions.

SUMMARY : Best clinic for laser Hair reduction follows the given criteria: Uses USFDA approved laser. Dermatologist supervises the laser treatments.
