The Kiierr laser hair growth cap is one of the several brands that belong to Low Level Laser Therapy (LLLT) for hair loss treatment. Some studies, though with a small number of subjects, indicate LLLT can halt or even reverse hair loss at its early stages. Although LLLT is generally believed to be less effective than the mainstream treatments like minoxidil and finasteride, it warrants some examination.
In this blog, we will compare Kiierr with several other very similar, almost identical products to help you choose the best product, and also give you specific information abou the guarantees of each, to help you avoid falling into a "fine print" trap.
How does it work?
delivering laser light to the scalp, energizing and activating hair follicles to stimulate hair growth.
What is included in the product?
The Kiierr package contains a laser cap (dome), sport cap, USB cable, wall charger plug, battery, and a manual (see image below).
Who can use the product?
Like the RegrowMD laser cap, this product does not work for all hair loss types and skin types.
How is the Kiierr laser cap compared to other brands?
There are several other brands of laser cap that look and work very similarly. They are listed below, side by side, for the model with 272 laser diodes. Some brands have a lower model with 148 laser diodes. They are not listed here to save space. However, their comparison is very consistent with the 272 model.
|Wavelength of laser (nm)||650||650||650||650||650|
|# of LED lights||0||0||0||0||0|
|Where is it made||China||USA||China||China||China|
At first glance, there is almost no difference between these brands including Kiierr, RegrowMD, Capillus, illumiflow and RedRestore. The main device is made of a plastic dome with 272 laser diodes mounted inside and a sports cap to cover the dome. The sports cap is for aesthetic purpose. The device can be used without it.
So what are the differences between the five brands above?
1. Price: as shown in the table above.
2. Features: Capillus is somewhat different from the other four in that its plastic dome is flexible while the other four have a firm dome. It also has a safety feature that the other four don't have: the treatment session will automatically pause when the hat is taken off the head. Capillus also has a mobile app, while the others don't have.
The other four brands including RegrowMD, illumiflow, Redrestore are essentially the same except that RegrowMD has a flexible Biolight Comfort (see below) for more comfortable wearing.
3. Battery: The batteries used by the RegrowMD and Capillus last much longer than other 3 brands. You can use them more than 10 times before you need to recharge it, while the other three brands recommend recharging the battery after every 3 sessions.
4. Satisfaction Guarantee: This is probably the most important factor when considering which cap to buy. They all sound very good. But that is only true until you read the fine print. Here are the details, current as of Feb 11, 2020.
a. RegrowMD: One year satisfaction guarantee. Buyer can return the product any time within one year, but needs to pay a 25% restocking fee.
b. Capillus: The same as Regrow MD.
c. Red Restore: One year satisfaction guarantee. Buyer can return the product any time within one year, but needs to pay a 20% restocking fee. The product must be in resellable condition. Otherwise, the return may be rejected or the buyer needs to pay a 50% restocking fee.
d. illumiflow: Six months satisfaction guarantee. Buyer can only request a return within six months after the purchase, and customer has a one month widow (from sixth to the 7th month after the purchase) to return the product. There is no need to pay any restocking fee if the product is in the same condition it was in when you received it, except for normal wear.
e. Kiierr: Seven months satisfaction guarantee. Buyer can request a return for refund only if he/she submitted a before photo. Buyer can only request return a seven months after the purchase and the customer has a mere 7 day window to do so. You'd better set some reminders on your phone,; otherwise, you will likely miss the narrow window.
In summary, illumiflow probably has the most lenient return for refund condition, while Kiieer's has the most stringent condition, which makes it almost impossible to get the refund if you do not return in 7 days after receiving the product and are willing to pay 20% restocking fee.
Price and Where to Order
The 148 diode model is $595, and 272 model is $845. The products are only available at Kiierr's official site, and are not available on Amazon.
As mentioned above, the Kiierr battery does not seem to last as long as than other brands. It requires more frequent recharging. The image below shows that the Kiierr battery is a little bit longer, but thinner than that of RegrowMD. The overall volume of Kiierr's battery is smaller than RegrowMD, which probably explains why it has less capability and needs recharging more often.
Kiierr Before and After Photos
The photos shown below are claimed to be the results of using Kieerr Laser Hair Growth Cap for a few months. Because only a partial view of the head is shown, it is really difficult to tell how much difference the product made.
Kierr is one of several laser hats for hair loss treatment on the market. Its price is on the lower side but not the lowest one. It has the strictest satisfaction guarantee conditions. The battery needs to be improved to be on a par with other brands. Overall, it is a good hair growth laser hat. For people who want to get good bang for the buck on a LLLT device, it is not a bad choice. One just needs to be very careful on the return and refund conditions in case you need to return it.
If you want to save some money, you should consider illumiflow, which has the same if not better quality than Kiierr but with more a reasonable satisfaction guarantee. If you have a deep pocket and want to have the best quality laser cap, you should check out the Capillus laser cap. If you want to pay for a reasonable price for a best built laser helmet, you should definitely consider the Theradome laser Hair Growth Device. One product that is quite popular online but you should avoid is iRestore that uses ineffective LED lights to beguile customers.
