Real People, Real Results

Susan G – After 3 Dermotologists.. Kiierr Worked For Me.

“I went to 3 dermatologists, all with different answers (even a scalp biopsy). Their answers didn’t make sense. I saw your advertisement and due to the fact I had 7 months to try it out, I bought it. It took patience….months to begin to see progress.”

/ Happy Kiierr Customer

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

“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: 22 Premier Model;not only is the battery life incredible.”

People Have

01 Which cap is the best for me?

We have 3 cap options: 148Pro, 272Premier and 272Premier-MD. The main difference is the amount of laser diodes, 148 vs 272. We recommend the 148Pro for those who are just noticing hair loss/thinning or want to prevent it. The 272Premier is recommended for those who want to see more significant results & noticeable regrowth. The MD cap is an upgraded version of the 272. It has many additional features including an upgraded battery, faster pulsing rate (which would help you see quicker results), enhanced laser diode panel, no reminder beeps and more! The MD cap comes in two sizes: standard and Elite. The Elite has all of the upgrade features but is larger & has more scalp coverage on the sides/back.

02 Will laser therapy work for my specific hair loss situation?

This is an answer that will vary. Basically as long as the follicles are still active, it can work. When they ask how to know if the follicles are active I tell them: To know if your hair follicles are still active, you would take a look at the scalp. If you see any hairs on your scalp—no matter how sparse, thin, short or fuzzy—your hair follicles are still alive. When your hair follicles have died, the skin on the scalp takes on a smooth, shiny appearance. 

Website Idea

Maybe we go through our reviews & pick out all the photo ones that reference why they were having hair loss. Then make a page dedicated to who it works for & link that on the home & product pages. We should also make a scrollable before/after section on the home page for results. We only have 1 on the home page. Also add on product page the different types of hair loss. 

03 How does a laser cap work & how long until I see results?
The hair follicle converts the red light into energy that stimulates your scalp’s blood circulation and increases your hair’s nutrient intake, resulting in healthier hair growth and the renewed functionality of hair follicles. Results vary depending on the degree of hair loss when you begin. The majority of users, after using the cap as directed, typically report visible changes in 4-7 months.
04 Can I get a discount? What is the best price you can offer?
We’re currently running some of the best pricing you’ll find all year. Feel free to take advantage before it ends!
05 I’m having issues ordering on your website, can you just place the order for me?
Yes! Please call us at 801-834-4970 and we’ll be happy to place your order over the phone.
06 What is the difference between the MD and 272?

The MD cap is an upgraded version of the 272. It has additional features including an upgraded battery, faster pulsing rate (which would help you see quicker results), enhanced laser diode panel and no reminder beeps. It is also made with more durable and quality components. The MD cap comes in two sizes: standard size and elite. The elite has all of the upgrade features but is larger & has more scalp coverage on the sides/back.

07 Do I need to use supplements? What do you reccomend?
The DHT blocking shampoo, conditioner, vitamins and other supplemental products will assist in quicker and more noticeable results. It is important that your scalp has everything it needs for optimal hair health.
08 How does your guarantee work? What is your return policy?

We have a 7 month growth guarantee! You would use the cap for a full 7 months & if you don’t see results, you can return it (you just need to register your device in the first 45 days with a before picture to be eligible). See the full policy here.

09 Does it matter the age? Does it help gray hair? Is it safe to use on color treated hair? Does it matter the texture or length of your hair?

Results vary depending on the degree of hair loss when you begin, rather than age. The majority of users, after using the cap as directed, typically report visible changes in 4-7 months.

LLLT (low level light therapy) is a great option for those who have chemically treated hair. The cap can help to provide longer lasting color with less fading and oxidation and will help repair damage normally caused by chemical services.

Laser therapy can be used on all types, textures and lengths of hair. The laser diode will penetrate through the hair follicles to target the scalp and increase blood low.

As we get older, the pigment cells in our hair follicles gradually die. When there are fewer pigment cells in a hair follicle, that strand of hair will no longer contain as much melanin and will become more transparent (gray, silver or white) as it grows. Consistent use of a laser cap will increase blood supply to the scalp which helps in cellular restoration to reverse or slow graying.

10 What size head does the cap fit?
Our standard caps fit up to 23.5” in circumference which would be a US 7 hat size. The MD Elite cap fits up to 24.5” which would be a US 7 1/2 hat size


Jolene & Mike


Mike and Jolene Anderson are the founders of Kiierr.

Jolene was experiencing post pregnancy hair loss and wanted a safe, effective, and natural way to regrow and strengthen her hair. Together Mike and Jolene researched various hair growth products and found that they were either ineffective, difficult on the body, or incredibly expensive. They discovered that LLLT was an effective treatment for hair loss but couldn’t make the time to go to the doctors office to use their device. This is when they decided to create Kiierr. Using the same medical grade diodes, Kiierr is able to provide FDA Cleared LLLT services for a fraction of the cost and at the convenience of your own home.
