The product i bought was black but it's still a different shade of black to my hair. I have too leave it overnight to let it blend to my natural hair colour. It has a scent of dog hair ( not throught but some sprinkles ) other than that I like the product and will buy again.

Another expensive product that doesnt do what it claims
I dont know why I keep getting sucked in to the fake reviews on here. Do these companies pay people to say their products are amazing when they know fine well that they dont work. My bathroom is filled with hundreds of pounds worth of products that all promised thicker fuller hair and none of them do any of what they say including this shampoo and conditioner. It does absolutely nothing.

Unprompted review
Reply from Nanogen
Hi Caroline, sorry to hear that you are not happy with the products - however, we work very hard to ensure our reviews are accurate, fair and real. We use Trustpilot for this reason, never delete poor reviews and try our best to make sure all our customers are happy.
Our fast growing British business has been helping people with thinning hair for over 20 years and we have had incredible feedback from thousands of customers over this time who have seen improvements to their hair.
Your hair grows on a 3 month cycle, and ingredients such as Pea Sprout Extract, Saw Palmetto and Peptides will help to improve the condition of your scalp to support hair growth over time. Real hair growth and hair health happens slowly, supported with a good diet and healthy lifestyle. We have always had great feedback for our shampoos and conditioners.
If you need something quicker, then our Hair Fibres or our Root Boost spray can give the instant appearance of thicker looking hair. These also have excellent reviews, and can help anyone looking to improve the appearance of thinning hair.
We offer a money back guarantee on all our products if you are dissatisfied for any reason. Just give Claire a message at hello@nanogen.com and she will happily arrange a replacement or refund.
It’s ok it does the job
It’s ok it does the job, although I’m not sure I’ll use it every day as I found it quite dry looking but good for emergency updos that leave gaps in my hair.

First time of trying and it’s a yes from me
First time of trying. Anything that thickens my
Hair is a plus. It’s a lovely shampoo (foams up beautifully) and conditioner (doesn’t weigh hair down). Hair does feel slightly thicker. Also used the thickening spray at the roots.

Satisfied customer
First time I’ve used Nanogen fibres and I am very impressed. It doesn’t ’clog up’ your hair or look conspicuous sitting on your scalp. It does improve the overall look of my hair and I will continue to use it and possibly try other products in the range.
