Below I will go over in detail the companies of Kiierr vs. Revian Red Hair Growth System review to give you some more information. These laser cap reviews will reveal the importances of each brand.

What is the Kiierr Laser Cap?

Kiierr 272 Premier Laser Cap Complete Hair Growth SystemThe Kiierr laser cap is a hands-free, portable hair growth device that is FDA-cleared for effectiveness and safety. These caps are designed to use low level light therapy to stimulate blood flow in the scalp and decrease inflammation. By increasing blood flow in the scalp, the proper nutrients and oxygen levels are able to be transported to the scalp to help regrow the hair follicles.

Kiierr’s hair growth system is placed inside the Kiierr ball cap or a standard ball cap of your choice. This makes this cap discreet and convenient. It will be worn every other day for a time frame of 30-minutes. All Kiierr caps are made with a built in timer, so after your 30-minute treatment is up, the cap will automatically turn itself off.

When getting started on your hair growth journey with Kiierr, you will have three different caps to choose from. The differences between the three are the amount of laser diodes they contain, along with the size of the cap. One cap (148Pro) contains 148 laser diodes. The other two (272Premier and 272PremierMD) contain 272 laser diodes. The 148Pro and 272Premier and the same size. The Kiierr272PremierMD cap is larger in size and offers a few other enhancements that you can find here.

The price of the laser caps that you will be looking at will range anywhere from $595-$1,395 depending on what cap you choose. The prices also reflect whether you just purchase the laser cap alone, or if you purchase the complete system. The complete system involves the laser cap and also the amazing hair growth supplements.

Customers typically report noticeable hair growth results around the 4-6 month mark, but there have been individuals that have seen results in as little as 3-months. If you are not satisfied with your purchase after using it consistently for atleast 7-months, Kiierr allows returns for a full money refund.

What is the Revian Laser Cap?

The Revian laser cap works in a similar way to Kiierr in that they are designed to regrow the hair follicles on the scalps of men and women. Their caps increase both thickness and density of hair follicles, resulting in thicker, fuller, and healthier hair.

The Revian laser cap is worn every day for 10-minute time periods. You will be able to start seeing new hair growth results after several months of religious, every day use. They offer a money back guarantee if you do not see results after using the product for at least 6-months.

Comparing Kiierr vs Revian Red Hair Growth System

kiierr vs revian red hair growth system

These two products are similar in the fact that they both strive to regrow the hair on the scalps of men and women effortlessly. Both Kiierr and Revian also offer free shipping on all purchases.

Kiierr contains strictly medical grade laser diodes while Revian contains only LEDs in their caps. LED lights aren’t as preferred, and many hair growth caps use these in their product to make a cheaper cap. While LEDs promote skin health and can even support wound healing, the light being produced from the LEDs typically aren’t preferred for hair growth and don’t have the same capabilities of that of real laser diodes.

A big difference between the two hair growth caps will be found in their guarantees and warranty. Kiierr offers a 7 month guarantee or your money back. Revian gives a 6 month guarantee.

The warranties also differ between the two products. Kiierr gives a two year warranty with each cap, allowing you to be confident and protected with your purchase. They also will send you a new unit, absolutely free, in case of any issues related to the cap. We were unable to find warranty information on Revian’s website.


Kiierr and Revian overall are very different products in terms of technology. When it comes down to being protected and having successful hair growth, Kiierr has you covered. They make sure you feel confident in your purchase with them and that you’re protected in case of malfunction. And the best part is, their caps work amazingly well.
