Kiierr is very responsive with any customer service issues and I've really been helped with their red light hat. Definitely would recommend.

Update: they claim delivery conveniently today (lie) but provide no tracking and won't respond to my credit card company and the credit card company is giving a full refund based on fraud. This company is a total scam. Beyond dishonest. *I ordered this product and paid $1200 and they have never delivered the product. They will not return my calls, my emails and their customer service chat is always down.I've had to file a complaint for a full refund with my credit card company.

Had a battery pack that wouldn’t charge anymore. Reached out and got a reply same day that they were sending me a new one. Excellent customer service.

Customer service is excellent. My charger is not working, so I asked to buy a new battery. Instead of taking my money they sent directions on how to trouble shoot the battery.

Trusting my belief in red light therapy to reignite my hair follicles. 5 weeks in and 6 minutes a day is a breeze. The Flex Cap is comfortable and fits well. Very optimistic about successful results moving forward and Steven at Kiierr Team has been incredibly helpful in the process.

Be warned do not trust Kiier shampoo and customer service. This is a scam. I ordered this three weeks ago and have not received the shampoo. I keep calling the customer service number, but there is nobody there. Everything is done through emails and they do not respond. This whole gimmick is just a scam you out of money. I was a victim. You have been warned do not trust KIIER

After using the red light cap for a couple of years and loving that, I also used the DHT blocking shampoo and conditioner and have recently tried their new hair dye shampoo. It’s been great so far! I find it much better than constantly dying my roots and it’s a more natural and subtle look that the skunk line I used to have. Kiierr has great customer service and I’m super happy with all the products I’ve tried!

A few months ago I was losing frontal hair rapidly. Now it appears that new growth has started. The cap is also easy to use and comfortable!
