Can a Laser Stimulate Hair Growth?

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.

Thank you for your question! 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. Best of luck!

Low dose lasers may stimulate hair growth (for example the laser comb that advertises hair growth).  The hair growth is generally very fine.  Lasers used for hair removal generally do not promote hair growth at the recommended settings for skin type..  Are than other factors involved (hormone, medication).?
