Kiierr Laser Cap Hair Growth System
Clinically proven FDA-cleared laser technology stimulates hair growth and prevents hair loss
Details
Kiierr laser caps, powered by our exclusive PureLaser™ technology, utilize only high quality medical grade laser diodes (no LEDs) to deliver precise, effective LLLT at 650 nm for optimal hair regrowth.
With options of 148, 272, or 302 diodes, and total power outputs of 740 mW, 1,360 mW, and 1,510 mW respectively, Kiierr caps offer targeted stimulation for fuller hair. Simply use the 148 and 272 models for 30 minutes every other day, or the 302 model for 6 minutes daily, and start seeing results in as little as 6–8 weeks, with significant improvements typically visible within 4 to 7 months.
How It Works
This advanced, FDA-cleared LLLT technology penetrates the scalp to stimulate hair follicles at the cellular level, enhancing blood flow and nutrient delivery to dormant follicles. The result is a revitalized scalp environment that supports natural hair growth cycles, promoting thicker, fuller hair that’s clinically proven to be effective. With over 100,000 satisfied Kiierr customers and a money-back guarantee, there’s no reason to wait. Experience the transformation for yourself and watch your hair thrive!
