NanogenInstant Thickening Hair Fibres - Medium Brown 30g - Natural Keratin fibers cover thinning hair, extensions, alopecia. Thicker, fuller hair instantly.

Very good hair fibre, does not make your hair feel stiff or dry, also cheaper on Amazon than the actual Nanogen website

Easily the best hair fibre in the market. Just too pricey compared to its main rivals

I`ve been purchasing Nanogen dark brown hair fibres since October 23. Lets get the negatives out of the way first: not the cheapest on the market and they can be messy.Now the positives: they give thicker looking hair and are very effective at hiding thin areas on the scalp.I have tried other brands but overall I find Nanogen the best- mainly because I think they adhere better. They work by static electricity and cling to the hair although some will fall on the scalp too- I think the static strip (which no other brand has) helps better adhesion.Here are my tips:1) Make sure your hair is totally dry before application otherwise the fibres will clump together.2) Less is more ! You don`t need loads on the hair. Sprinkle on thin areas (typically the crown) and then lightly pat the hair to settle the fibres. Repeat this until you are happy with the coverage- but don`t overload the hair- they will fall off if too many are used.3) Use the "salt shaker" provided to cover larger areas. For smaller areas use a spray applicator: here there is a problem because Nanogen don`t make one ! I bought a small 7g Gofyber sample bottle and a Toppik applicator for this and simply carefully pour some of the Nanogen fibres in to this. The spray applicator is ideal for partings and hairlines. Make sure you buy a hairline optimizer to cover the forehead when using the applicator on the hairline to keep things neat. I find a makeup brush is ideal to tidy up the hairline as well.Overall, a great product if applied correctly. LESS IS MORE ! Remember that the fibres need hair to cling to though- they will look very unnatural on completely large bald areas. A 30g bottle lasts me about 5 weeks.

I used Toppik for a few years but they have now doubled the price and so I searched for an alternative. The reviews for Nanofibre seemed positive so I gave it a try. It's half the price of Toppik and nearly (not quite) as good. It's worth the trade off. Colour match is perfect, the fibres stay in all day, haven't tested in the rain yet but Toppik struggled with that anyway. The only critique is the bottle is hard to dispense from, it seems just a bit more clunky. Otherwise it's great and I've now found the product that will replace the extortionate Toppik.

Really good! Woll but again.

This product is truly amazing! It effectively covers thin areas and adds significant volume to your hair, making it look completely natural. Although it's recommended to use a hair spray for a better hold, I found it unnecessary. The powder adheres well to both hair and bald spots, staying put even in strong winds. It's made from 100% keratin and has no side effects. I highly recommend it for styling your hair and adding volume with a natural look. I use the dark brown color, and it matches my hair perfectly.

I did thorough research before purchasing this product. I’ve used other brands before, and although my hair isn’t very thin, I was disappointed with this product. I wanted to use it for 2 months before writing a review, but the result was a letdown. I wish I could write a positive review, but the product simply does not adhere to the hair properly. Even when using hair spray or fiber-holding products, the moment you touch your hair, your forehead ends up covered in dust. I don’t usually leave reviews, but I felt the need to share my dissatisfaction with this product.

It works (kind of).I'll keep this short:Pros- Genuinely does 'create' hair where it previously looked like there was none.- Doesn't look too artificial in some lights. Not THAT easy to notice that it's fake.- With the use of hairspray product will stay in place for maybe 8 hours indoors when affixed with hairspray.Cons- MUST be affixed in place with hairspray. This means no matter how you used to style your hair (or not) you are now commited to having a hairstyle that is affixed in place with hairspray.- This also means your entire head is now a rock hard helmet of hair and microfibres.- YOU CAN'T TOUCH after application. Don't listen to other reviews you cannot adjust your hair in any way. The product will immediately clump into gross balls of fibres and you'll need to shampoo out and start again.- Looks artificial in some light. The 'new' hair can look metallic and shiny compared to existing hair.- Slightly awkward to apply. I would recommend getting someone to help if your bald spot is at the crown. Difficult to work in 2 mirrors at the same time!- YOUR HEAD IS NOW ALLERGIC TO RAIN. In Britain. Think about that.Overall I do like Nanogen Fibres the immediate WOW effect is worth buying this product once for. However I simply cannot imagine using this more than every once in a while for special occasions.PS - Everyone WILL NOTICE that this is fake hair. Don't kid yourself!
