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.

Growth and Volume!

I’ve been using this hair growth serum for about 2 months, which is how long my first bottled lasted, and I’m seriously impressed. It’s super lightweight, so it doesn’t leave my hair greasy or heavy, which is awesome. I’ve used it morning and night, and it works perfectly both ways. Plus, you can put it on wet or dry hair, which makes it really convenient.

I’ve already started noticing more volume and some new growth. My hair feels so much healthier and softer, too. The scent is really subtle and clean, which I like a lot.

The only catch is that it’s a bit pricier than I’d usually go for. But honestly, it’s been worth it. Given the results and how easy it is to use, I’m definitely sticking with it.

This serum is great!

I have tried about 6 serums for growth and this is my favorite! I am seeing growth but also it gives my hair volume as it was lacking. I like the bundles but also wish it was available in a store.

Makes hair stiff

Can’t use and style. Can only use this product if you intend to wash your hair the next morning. Leaves a thick residue and makes hair matted looking.

Hi Ashley,

Thank you for taking the time to review our product. We’re sorry to hear about your experience. Our product is aloe-based and specifically designed to leave no residue. Most of our reviews highlight the absence of residue as one of the reasons they love it.

The product is meant to dissolve on your scalp, and it may warm and dissipate more if left on longer. If you're looking for less volume or 'residue,' we recommend trying to leave it on for a bit longer than the 10 to 15 seconds stated in the directions. As with all products, individual results may vary.

We hope this helps, and we appreciate your feedback!

Best regards,
Team KYIR
