Laser Hair Restoration FAQs

Does the laser treatment really work?

Yes! Low Level Laser Therapy (LLLT) has been well-researched and in medical use since the mid 1960’s and was also used for many years in Europe to treat patients suffering from hair loss.  In the last decade, clinical research in the United States has proven that low energy laser wavelengths in the red light spectrum can effectively stop hair loss and regrow hair.  Recent U.S. FDA clinical trials have demonstrated that low level laser energy at 650 nanometers stabilizes hair loss for both men and women and regrows hair in 93% of patients who receive treatment.

Is it painful?

No. The Sunetics laser uses Low Level Laser Energy at a very low energy wavelength.  The laser light emitted is non-thermal, painless and cool to the touch.

How does the Sunetics laser work?

Low Level Laser Therapy works by a process called ‘Photobiostimulation.’  Photobiostimulation involves laser energy reawakening dying and miniaturizing hair follicles and bringing new life to these follicles, turning them back into larger, healthy terminal hairs.  The laser energy penetrates ~ 4mm deep where the dermal papilla – the hair follicle root - resides.  Blood flow and capillary size is enhanced.

The laser energy also decreases inflammation and repairs the follicle at the cellular level, resulting in smaller balding hairs being ‘rebuilt’ into larger, thicker terminal hairs.  Studies show that low level laser energy also converst ~70% of resting hairs back into the growth phase.

Are there any side effects from laser treatments for my hair?  Is it safe long-term?

Low Level Laser Therapy at the wavelength employed by the Sunetics laser has been in use for over 45 years.  The laser only penetrates as deep as the hair follicle and stimulates cell function. The effect is non-thermal in contrast to surgical or hair removal lasers. The laser's low level energy does not alter molecular structures, but stimulates the body's mechanisms to repair and heal itself. This laser can also be used for wound healing and that is why there are no reported side affects.


  • Women who are pregnant
  • Active herpes infection (cold sores) in the area to be treated
  • Skin infections such as impetigo at the site to be treated
  • Extreme sensitivity to light
  • Active skin cancer
  • Glaucoma, cataracts or retinal detachment

Who is a candidate?

Both men and women benefit from low level laser therapy and are candidates for the Rejuvenate laser hair treatment program.  Women make excellent candidates for Low Level Light Therapy Hair Restoration, given how well this technology works for diffuse thinning and post-menopausal hair loss. Men will benefit from LLLT as well, using this therapy as a 'stand-alone' drug-less treatment therapy or by combining it with their existing regimen of Propecia and/or Rogaine.  A consultation is essential to determine your degree of hair loss and the right treatment program for you.
