Brandon Shares His Kiierr Laser Cap Success Story

“My mom was telling me about a laser light cap that helps you grow hair. I ordered it to try it out. I wear it every other day for 30 minutes. You can wear it at home or on the go. I’m telling you, man, it really works!” -Brandon Wise

Mark G. Late 30’s – Amazing results in 6 months!

Kiierr Laser Cap Review - before and after hair growth image (1)
After years of experimenting with several products (which almost always left me with a long price tag & short term results.) I decided to invest in the Kiierr Laser Cap: 272 Premier Model; not only is the battery life incredible (providing multiple treatments with ONE charge) but after only SIX months of continuous use there has been a remarkable improvement in the strength, structure, and integrity of my existing hair with noticeable growth in those previous ‘problem areas.’

Kiierr Laser
Hair Growth Cap

The Kiierr laser hair growth cap is a powerful, cutting-edge low-level laser device for the treatment of androgenetic alopecia (pattern baldness). The 272 independent laser diodes are contained in a sealed unit that is powered by a lithium battery.

The unit is inserted into the black cap that we provide or any hat or cap that you choose. A battery charger is included. Kiierr laser technology is backed by clinical trials and cleared by the FDA for the treatment of hair loss. Laser hair growth treatment is a revolutionary new option for those who suffer with laser cap for alopecia (hair loss based on genetics). The Kiierr technology is completely portable, and you can grow hair inconspicuously anywhere at any time: at home, at work, driving, running errands.

How does Low Level Laser Light Therapy work for hair growth?

Hair is constantly growing, resting and then shedding the old hair shaft before growing again. With pattern hair loss, the hair becomes progressively thinner and lighter in color with each growing cycle. The cycle keeps repeating until the hair follicle is atrophied.

Low level laser light therapy improves cellular respiration, so that hair stays in the growth phase longer, reducing the duration of the dormant stage. This results in the hair growing back thicker and darker, with the hair loss being reversed, stopped or slowed down. – Shop Now

Is there a warranty if my Kiierr Cap stops functioning properly?

Yes. If you experience issues (very rare) with your device functioning properly, we will pay for return shipping and quickly ship you back a new device.

Our warranty covers your Kiierr Cap for two years from the date of purchase. It protects against factory defects and workmanship errors. If your unit has stopped functioning within this time period, please contact our customer service department, so that we can help you with your warranty return. – Shop Now

Testimonials

Reid age 60 - Amazed at the results after 5 months!!

Reid Fix Kiierr Laser Cap Testimonial Image

This is proof this product works.  I am a man in his 60’s that has male pattern baldness.  I saw this on the local news channel in Las Vegas, Nevada that was covering the Consumer Electronics Show, and thought it looked interesting but did not purchase it.  The following year (and a lot more hair loss) I again saw it on TV the next time the convention rolled through.

This time I thought I’d give it a try.  The photos were taken 5 months apart, I am amazed at the results.
