100% effective. My hair was going really fine around the front and was very noticeable. The nanogen powder made my hair look fuller and hid the fine patch's.

The Thinkening spray smelt very clinical, and made my scalp itch after the first application.

I have already given 2 reviews of this , but it keeps reminding me! The product is appropriate for the purpose it specifies. But the company shipped the wrong colour twice, eventually got it right the third time . Customer service responded promptly each time , but that doesn’t make it less annoying. Hence 2 stars

Best I Have Used
Tried a few hair fibres over the years but Nanogen is definitely the best. Easy application and completely invisible. Highly recommended. Blends seamlessly.

I was advised by a dermatologist to use this after I lost my hair as a result of chemo. I think it's fantastic and have recommended it to lots of my friends. I can literally feel the extra small hairs growing and my hair is now long and in great condition. I'm committed to Nanogen

Applicator
Hello,
I really like Nanogen hair fibres and prefer them to Toppik, but the applicator is a problem. I actually transfer my Nanogen fibres into an old Toppik bottle because its applicator works much better.
I know several other people who do the same, and some buy Toppik instead purely because of the applicator. It would be great if Nanogen could improve the bottle and provide a reliable, easy-to-use spray applicator with the fibres.
I thought this feedback might be helpful, as the fibres themselves are excellent.

Hi Geraldine,
Thank you for your feedback and support. We are thrilled you prefer Nanogen hair fibres over other brands
We appreciate your concerns about the applicator design and the need to switch bottles for precision. I have escalated your insights directly to our New Product Development team to help us improve.
Thank you again!
