Obsessed with my new hair care routine

This hair serum is an absolute game-changer! I’ve tried countless serums in the past, but none compare to this one. It has made my hair feel noticeably thicker and healthier. I love that I can use it both in the morning and at night without it leaving any oily residue. It absorbs beautifully and allows me to style my hair perfectly every time.

I’m beyond impressed and excited to see the continued results with consistent use. Highly recommend it to anyone looking to upgrade their hair care routine!

Volume + New Hair Growth

I was always skeptical of hair serums because of how greasy they would leave my hair. With thin hair I was worried it would weigh it down, then I saw a few ads of Fuller and decided to try. This really did give me instant volume without the greasy feel. I’ve been taking this for a little over a month and I do see baby hairs on my hair line. I’ve recommended it to my sister and friends !

10 stars!

I’ve been using this for several months now and don’t think I can ever stop. Even my barber has noticed a difference in my hair. I love the scent, the light weight feel and how it helps when styling my hair. I’d give 10 stars if I could!

Great results

I have been using for about 3 mos, with great results in hair growth and volume. I did not think to reorder in time prior to running out of the product and there was a noticeable difference.
I am going to set up on auto ship! I love the smell, it is clean and lightweight when styling on both wet and dry hair. Thanks KYIR.

Life after beta blocker hair catastrophe

In March I was prescribed metoprolol for a heart issue and high blood pressure and by early June I was losing hair at my temples and having noticeable thinning. My cardiologist switched me to Carvedilol two weeks ago and it looks like the shedding and thinning is abating but a lot of damage was done. I’ve been using this serum for only a week but it is giving me noticeable volume and definitely disguising the havoc caused by the metoprolol. I am thrilled with this product. Generally hair grows back in 6 months or so after dropping metoprolol but this serum will cover me and for that I am so grateful.

Thank you so much for sharing your experience! We’re thrilled to hear that switching to Carvedilol has been beneficial and that our serum is providing you with the volume and coverage you need while your hair recovers. Hearing stories like yours is exactly why we created Kyir—we’ve also experienced hair shedding and understand how challenging it can be. We’re committed to helping people through this process, and it’s wonderful to know our product is making a positive difference for you.
