Hi there, thank you so much for your review. We are so pleased to read that you are seeing a visible difference to your hair after using our Shampoo. You are exactly right that it takes time for our Nanogen products to work to their best - hair growth cycles are a 3 month time span, so with any hair thickening and growth products, it's important to build this time in when looking for results. Thank you for sharing you feedback. Enjoy your Shampoo!
It really seems to working! I've just started using the shampoo and…
I've just started using the shampoo and conditioner and my hair looks healthier and really feels thicker and shiny too.

Fingers crossed
The ordering process was easy- grey and white fibres. Delivery was smooth and prompt. Have not used products yet but as a female with hair loss, I hope the products will at least disguise my shiny scalp. If yes, I'll be back for more.
