Customer Reviews
Hair Growth Vitamins worked
Got the Hair Growth Vitamins. Shipped fast. Been taking them a month. My hair feels a bit thicker. Will buy again.
Decent cap, slight shipping delay
I bought the DualWave Laser Cap 272 Diodes a few weeks ago. The cap itself seems like good quality and is comfortable enough to wear. I appreciate that it's FDA cleared, which gave me some peace of mind. Shipping took a little longer than expected, about 8 days to reach the East Coast, which was a minor annoyance, but not a huge deal in the grand scheme. Customer service was responsive when I inquired about the tracking. It's too soon to see dramatic results, but I'm optimistic and will stick with the routine. The price point is a bit high, but I guess that's expected for this kind of technology.
Love the bundle!
Oh my goodness, I am so happy with my Hair Growth Bundle! I got the Kiierr 272 Elite Laser Cap and all the goodies that came with it. Everything arrived super fast, like in three days! The cap is so comfortable, and I'm already feeling like my hair looks a bit healthier after only a couple of weeks. The shampoo and conditioner smell great too. This was such a great purchase, I'm telling all my friends who are dealing with thinning hair!
Easy to use, quick delivery
I finally decided to try one of these laser caps, went with the Kiierr 148 Pro Laser Cap. It came quicker than I thought it would, probably five days to get here in Texas. Packaging was good, everything was safe inside. It's super easy to use, just pop it on for the time it says. Not a hassle at all. I'm hoping to see some results soon, but so far, the whole buying and starting-to-use part has been smooth. No complaints from me.
Good cap, excellent support
I ordered the Kiierr 272 Premier Laser Cap after looking at a few different brands. The ordering process was pretty straightforward on their website. It shipped out in about two days and took maybe another four days to reach me in California. I had a question about the usage schedule once it arrived, so I called their customer service. The person I spoke with was really knowledgeable and patient, explaining everything clearly. The cap itself feels well-made, not flimsy at all. I've been using it for a few weeks now as directed, and while it's too early to see major hair growth, my scalp does feel healthier. It's comfortable to wear while I'm doing other things around the house. Overall, a solid product and a good experience with their team.
Kiierr Community Discussion
Share tips, ask questions & help fellow shoppers save more
What's the real difference between the 148 and 272 laser caps? Is the more expensive one actually worth it for more diodes?
I saw something about a 7-month money back guarantee. Is that for real? Like, if I don't see results, can I actually get my money back?
Hey, thinking about getting one of these laser caps. Anyone know if they actually work or if it's just snake oil? Seen some mixed reviews.
Is Kiierr legit or like some random internet brand? Anyone know if their caps are actually FDA cleared?
Does anyone know if they do any kind of discounts for healthcare workers? Or like, a military discount?
