Can a Laser Stimulate Hair Growth?

I have had laser hair removal with Lumenis Lightsheer for 6 sessions. I am not seeing any improvement after the 4th session. Actually, on the 4th session, when the doctor increased the setting, I noticed hair grow back more and darker. Should I continue the treatment? Or I should switch to another Laser or clinic?

Low laser fluences (energy) may lead to hair growth

+2

Current research indicates that using sub-optimal fluences (energies) for laser hair removal treatments is a leading cause for the stimulation of hair growth – not a desirable effect when trying to remove hair.

One possibility why this may be more prevalent in darker skinned patients is because practitioners may be hesitant to use appropriate settings or do not have the correct technology (ex: long-pulsed Nd: YAG laser) for this group of patients.

We believe that a practitioner should not have to trade efficacy for safety if they are using correct technology, have a good understanding of skin typing, and choose safe, effective settings with each and every treatment.

Because we now see a growing trend in the use of low emitting diodes for the stimulation of hair growth, it’s plausible to consider that this concept would apply to treatments wherein sub-therapeutic laser fluences are being utilized. Rather than inhibiting hair growth, the negative outcome of using energies that are too low may be a stimulation of hair growth.

Hair growth with Lightsheer

+2

Well, it has been reported that some of the laser technologies used to remove hair, have indeed induced hair growth at lower settings. First of all, if you feel your condition is getting worst during this treatment regimen, then stop the regimen. Second, I would review the issue with your dermatologist, and make sure nothing else, like a hormonal imbalance, is being missed. Third, consider using another laser technology, like the Nd-YAG or Alexandrite.

Hair Growth and Laser

+1

Results vary from client to client. There are many different circumstances that can limit or change the results. (Hormonal, possible medications, underlining conditions) remember to be open with your provider to anything that may limit or change your results. The more your provider knows about you,  the better they are equipped as to what direction to take in order for you to have the best results. That being said, a laser does do minimal exfoliation during the treatment which can initially cause what may seem like a sudden growth in hair. This is because your hair grows in 3 different stages, Anagen (Baby stage) Catagen (Active stage) and Telegen (Resting stage).  Again results vary from client to client. Some may notice the hair growing out pretty much imidiately. Others it may appear that the hair is grown more. Relax, hair removal is a process and will take time to achieve results. The Lightsheer laser is equipped so that the provider can adjust the setting accordingly, Up or down. So as the provider is aware of how your skin reacted with treatments the more aggressive they can get during each session.

Hair removal takes time

+1

First of all, I truly doubt that any laser used for hair removal could cause more hair regrowth, especially if a very good laser like the Lumenis Lightsheer is used. Patients are sometimes unclear that even with lasers, hair removal takes many sessions and a fair bit of time to see improvement. However, comopared to old-fashioned electrolysis, it is more than 100 times faster.

Before switching to another physician or other laser treament center, I would speak to the doctor and ask him a few questons:

  • How many treatments does he think it will take before you see noticeable improvement?
  • How much will it cost?

I have a patient, who is not seeing me for his hair removal, who told me that he decided to get electrolysis to remove his fairly densely hairy back. He went every week for an hour over a 2 year period until it was declared that he was finished- that is over 100 electolysis treatments.

You just need to be patient and understand that hair removal is a process, but eventually you will get the results you are looking for.
