Is the LaserCap's low level laser light effective to re-grow hair? 
The LaserCap uses the same laser diode wavelength and output power per laser as an FDA-cleared low-level-laser device for hair re-growth; however, the LaserCap has 224 laser diodes versus 9 laser diodes in the FDA-cleared device and the LaserCap treats the entire affected scalp with an accurate and adjustable light dosimetry. The LaserCaps dosimetry may be set significantly higher than the FDA-cleared device and significantly higher than in-office dome devices: this higher dosimetry combined with consistent regular use (i.e., patient compliance) may be essential for effectiveness, according to the photomedicine experts. The LaserCap maximizes patient compliance since it is worn under any head cover (baseball cap, scarf, etc.) and is completely portable as it is powered with a small belt-clip battery pack. The LaserCap is currently in pre-clinical studies in preparation for formal clinical trials to receive FDA 510(k) clearance as a hair re-growth device if clinical efficacy is demonstrated. No medical claims are being made in regard to the LaserCap at this time.
