Better Than Sprays

I have been using Mane thickening spray for some time (expensive!) and decided to try the "shake on" fibres instead. Pleasantly surprised at the results - more natural looking and overall less mess since you control the application more directly. Just some advice for anyone who, like me, was apprehensive about using fibres.1) Apply fibres to CLEAN, freshly shampooed and DRY hair without any product such as gel or wax. The fibres attach to the hair better this way. You can style your hair once the fibres are applied as long as you do so gently.2) The colour you use is a matter of experimentation. I used a mid brown Mane spray, so I just went for medium brown fibres. They are slightly darker (also probably to do with the brand being different), so I will probably try the next lighter shade. However, I kind of like darker hair and have no issue with people assuming I've dyed it!3) Order a good spray applicator. When I say "spray" I mean you're still using the fibres, but the applicator uses a thin nozzle to pump and target the fibres in a more precise way. Good for hairlines. I use the Fab Hair Fibre Applicator.4) Don't just pour on the fibres and use a fixing spray. Pat them down and work them into the hair a little, maybe comb/brush lightly to distribute the fibres more evenly. People complaining about "clumps" or an unnatural look are probably neglecting this step. Have patience!5) For crown thinning, place the shaker close to the scalp and use a circular motion occasionally tapping. In fact the circular motion is generally good for optimum distribution. Use a hand mirror to ensure you have an even spread. This takes some practice but you'll get it!6) If you're doing the hairline you will inevitably get some of the fibres on your forehead. I use a razor to carefully scrape down from the hairline and then brush off the excess with one of those clipper cleaners. You can also use wet wipes.7) Don't wash your hair every day. There's really no need and you will save money by only having to apply fibres every other day. Using a good fixing spray will keep your hair protected and looking clean for a couple of days and the fibres won't go anywhere until you wash.8) Yes, it can be messy. But the more it becomes your routine, the better at controlling the mess you'll become. Using an applicator pump helps to control it. If you live with other people, do them a favour and wipe down after use! Just common sense really.Even though the above steps seem time consuming, once you have got the hang of it, you should have everything done within 5-10 minutes or so. I think these fibres would have far more 4-5 star reviews if people followed the above steps.

AMAZING product!

This product has been a Godsend for me! Great coverage for my thin edges and looks completely natural like strands of hair!! Doesn't run or come off on your hands and clothes. A little goes a long way. Price was excellent for quality?

Wonderful Stuff!

After a little practise it works very well and covers those thinning areas convincingly. Just tip your head forwards/downwards a little and sprinkle the fibres from around 12 inches above your hair for a natural looking cover. Should last you ages too.

Great price !!! Great quality !!

I always bought nanogen at £29.99 for a 30g pot, was sceptical as these were such a good price. I literally haven’t noticed the difference except in my bank account. They do exactly as they say and no one ever notices anything. I will be re-ordering thanks

Cheap and REALLY EFFECTIVE Results!

Bought these Hair building Fibres for myself and my mother who suffer from some intermediate hair thinning to wear at parties, social gatherings etc.Despite the product only being 22g, the hair dispenser is really tailored towards ensuring enough product is being applied whilst conserving a large amount of the fibres, making this product last very long and justifying the price (lasted around 1-2.5 months with moderate use). The fibre colours itself is aimed for a thick SHARP black and WILL STICK OUT if the natural hair is any other colour (although you might get away if you apply some to your fingertips and apply at the base of the scalp to act as black roots). The application process is really easy and due to the fibre powders being quite fine, even a mess up can easily be cleaned up/wiped.==Overall Review==Advantages:+Content of the Container lasts very Long!+Good results for people with dark black hair (be careful when applying for other sets of hair)+Sticks to scalp, giving it a NATURAL full-set-of-hair appearance+Can be washed out easily with shampoo+Relatively Cheap when compared to other products!Disadvantages:-Relatively small container (with just 22g of content) which when abused won't last long-If not careful can stain with vigorous use-Shade of black really darkIn conclusion I would HIGHLY recommend this product to anyone seeking a temporary relief, with it looking natural enough to wear at special events such as weddings.-Shaker
