“As you can see, compared to the Dec. 2022 head-shot photo there has now been substantial regrowth of new hair filling in the previously thinning areas. So, I am very pleased with the results of using the Kiierr 272 Premier Laser Cap. The Kiierr Laser Cap really works! No doubt about it. Highly recommended.”

“I purchased my Kiierr cap in 2020 and it has been a great investment for me and my self-esteem. I use it in combination with topical Minoxidil and it really has helped fill out my thin patches. Customer service is helpful and responsive. I definitely recommend this cap if you are looking to get the best results.”

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!

During this phase, you can expect about 10% recovery as the initial steps of hair regrowth begin. This stage often focuses on stabilizing hair loss, with noticeable reduction in shedding for most users. Results during this time will vary depending on the degree of hair loss you started with, as those with less advanced hair loss may see quicker signs of improvement.
By this point, you may notice up to 20% recovery, with subtle regrowth and thicker, healthier-looking hair becoming more apparent. Shedding should have significantly reduced, if not stopped completely, as the follicles respond to treatment. Keep in mind that individuals with more severe hair loss may experience slower progress during this phase.
Hair regrowth continues with up to 30% recovery, as new hair begins to fill in thinning areas and existing strands become stronger. Results at this stage depend on the severity of your initial hair loss, with those in the early stages of thinning likely seeing more visible changes compared to individuals with extensive hair loss.
Significant progress occurs beyond this stage, with up to 90% recovery for many users as new growth becomes fuller and more consistent. This phase is where the most noticeable improvements happen, but the timeline will vary based on your unique hair loss pattern and response to treatment.
