Great product!

Just ordered my 5th bottle. My hair is growing and I love you can use it on wet or dry , clean or unwashed hair. I wish Kyir had more than just this serum. Great scent profile.


The most effective hair growth serum I’ve ever used!


Only received one product the box was not sealed.

Hi Fady, We are sorry to hear you didn't experience the best delivery while your KYIR products were going through customs. It looks like customs might have opened your box while in transit. We hope you enjoy the replacement products we sent your way!



I can’t give a full review since I just received the package yesterday, but I am pretty sure I’m going to love it. I tried it yesterday for the first time it felt refreshing and the consistency was amazing. It felt great on the scalp. I can’t wait to continue using this product, and give a further review
