A Great Addition To My Haircare Routine!

I use a nightly growth serum on my scalp but I was missing a serum that I could use every morning after scalp massaging and hair brushing. Kyir's fuller active hair serum works beautifully for this purpose. It feels light( my scalp soaks it up), and has a lovely, delicate scent. Of course, I am using other products in conjunction with this, as well as doing other things such as taking hair vitamins, deep oiling, scalp massages, and consuming more protein, etc., but I can tell that Kyir makes my scalp really happy.


Really works!


Love that it gives volume and doesn’t make my hair feel greasy.

Hair Growth

A close friend of mine cynthio from the UK mentioned this changed his hair and scalp over all health. So I figured I give it a try. I must say this product has changed my entire hair routine !
Love the way my hair feels in the morning after using it at night .
My hair is long and blond and I’ve always been noticed for its length! Thank you for making a clean product xoxo

Seeing Great results!!

Seeing very noticeable results! My thin areas are filling in with new hair. I like that the product isn't sticky and it dries pretty quick too. The container is top quality too, it seems to be made out of glass not the usual plastic. I'll will definitely buy again based not only due to the positive results but also due to the quality of the container. I initially bought two bottles, once I'm finished, will start a subscription.
