272 Premier MD Laser Cap review
Laser diodes, not LEDs, which matters for hair: the clinical evidence for hair regrowth is built on low-level laser therapy specifically.

What we like
- 272 true 650nm laser diodes rather than LEDs
- FDA cleared for hair growth since 2018
- Seven month money-back guarantee is the longest in the category
What to know
- Over a thousand dollars
- Results need six months of consistent use
- Its headline output figure is diode count times 5 mW nominal, so it measures nothing about delivered light
