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.

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!

 

7-Month Growth Guarantee: Use your laser cap consistently for 210 days. If no growth is seen, return it within 210-240 days for a refund (25% fee, waived if 7 month photo documentation is provided). Registration with a before photo is required within 45 days of receiving the cap. See full policy for details.

Warranty:Kiierr laser caps come with a 2-year warranty, which covers any defects or failures. 

Shipping: Orders normally process within 2-3 business days and are shipped with 2-Day Shipping via USPS Priority or FedEx. However, our current processing time is approximately 7-10 business days due to high order volume. Shipping within the US is free. We ship to all countries and international shipping is $55 USD (plus customs fees charged by FedEx)

About Kiierr

Will laser therapy work for my type of hair loss?

Absolutely! The great thing about Low-Level Light Therapy (LLLT) is its versatility! Whether you are male or female, 18 or 88, from pattern baldness to hair thinning due to stress or medical conditions like including alopecia areata, hormonal imbalances, telogen effluvium and so much more.

Users of all hair textures and skin tones have seen incredible results, regardless of age. Start your journey to thicker, healthier hair today and see why so many trust Kiierr for their hair growth needs!

We have 4 laser cap options: 148 Pro, 272 Premier, 272 MD Elite, and 302 MD Ultra Flex. Choosing the right cap depends on your specific needs. For early stages of hair loss or those on a budget who are okay with slower, steadier results, the 148 Pro is ideal. If you’re seeking more significant and quicker regrowth, the 272 Premier is our bestseller.
