Vegan Hair Loss Concealer

"I use Boost N Blend and Rootz together for total coverage. It's expecially great when my grey is showing through. Can't live without these products"- Ann W, Perth

Cotton hair fibres cling to the hair shaft, making each strand of hair up to ten times thicker. This disguises visible scalp instantly and restores confidence.

This is a product developed by women for women. Not a repurposed men's product full of animal sourced keratin and a bunch of chemicals you won't want anywhere near your scalp (if you are hoping to grow your hair back).


Grey Hair and Scalp Concealer

Cover grey roots quickly and easily. The reflective colour pigments in this professionally designed powder cling to your hair, easily covering grey regrowth. RootZ is waterproof, won't rub off and is easy to apply. 

You can use RootZ on it's own, or alongside your Boost N Blend hair fibres. RootZ works brilliantly on areas of your scalp where your hair is very fine you can brush some on your scalp directly to give the appearance of even thicker hair. 


Large 25g bottle (up to 100 applications)

There are lots of ways to hide hair loss. Wigs, coloured sprays, changing hair styles, headbands, hats.

But there is only one way that always works, always hides visible hair loss and doesn’t compromise your follicles and the ability for you to grow hair back.


The natural ingredients in cotton hair fibres do not clog hair follicles (like the sprays do) and do not run if you get caught in a rain storm (like keratin hair fibres do).

Boost N Blend cotton hair fibres for women was developed by our founder and CEO, a nurse and herself a hair loss sufferer.

As she tells it, “there isn't a hair fibre specifically for women, they are all made for men and claiming to be unisex”.  Boost N Blend is still the only hair fibre product specifically developed by women, for women, in female hair colours.

Yes, you may be surprised to know that men have different hair to women. Different texture, different colours, different greying patterns. So their needs are not like ours.

We consult with hair colour experts on a regular basis to ensure our cotton hair fibres are the best hair colours they can be. We work tirelessly to bring you the best version of these products that can be made, and we ensure that our products are kind to hair. We know from our testing that hair can and does grow back, while using Boost N Blend on thinning areas.

Coloured sprays are messy and contain a huge list of chemicals that you would be best never to put on your scalp. Dry shampoo also has a long list of chemical ingredients that can exacerbate hair loss.

Boost N Blend does the work of both the sprays and a dry shampoo as it colours your roots, covers your scalp and soaks up oils.

Cotton’s cling factor: These clingy little fibres stay in during high wind (our founder loves a fast speed boat and can attest that they never budge), they even stay in when you get caught in the rain…

“I was caught for two hours in the pouring rain in a recent flood event, and I ran to the mirror to check on my hair fibres and was so relieved to see they were still there, even though my hair was saturated”

Do you sweat at the gym? There are many horror stories of women with green dye running down their face from using cheap hair fibres and sprays which liquify when in contact with water.

Not Boost N Blend. Our fibres are colour fast and never budge until you wash them out.

How to apply: Shake in or apply using our puffer applicator onto clean, dry hair. Blend in slightly with finger tips and apply a light hair spray if you like. It’s that simple.

Ordered the wrong colour? No problem. We offer a free colour swap to all new customers if the colour you choose is not right. We know the importance of getting the exact right hair colour and it’s not always easy to do. If in doubt or between two colours, choose the darker of the two. That way you are guaranteed to keep your roots and scalp in shadow. Exactly where it should be – not a shining beacon. 

"This product has restored my confidence" - Stacey W

"I can honestly say I was skeptical that it would work to cover my thinning part line but it is AMAZING! Thank you." - Rhonda M

Boost N Blend is available in a 25g bottle which is enough product to last 2-3 months, even longer depending on how much you use, of course!


Use Boost N Blend on clean dry hair. Shake Boost N Blend onto thinning area and using your fingertips, blend in with your existing hair. 

Repeat until desired effect is achieved. 

For best results and maximum electrostatic cling, use on clean blow dried hair. A light spray with your usual hair spray will help to keep your style in place all day long.


If your shade needs a little tweak, it is easy to combine two colours. The best way to do this is to apply the darker colour first then add a light sprinkle of the other colour on top. 

Blend in with your finger tips and continue applying both in that order until you are happy with the blend.

Do not combine two colours in the container. The shades we have developed are finely balanced to suit the broadest range of female hair colours - both nautrual and coloured. 


Wash and style hair as usual. Use wide end of brush to paint  Rootz onto the grey roots along the part line. For extra coverage you can use RootZ on wet hair.


Rootz can be applied to wet or dry hair. Use the wide end of the brush to paint Rootz onto your hair at the roots, and allow to overrun onto your scalp. If too obvious on the scalp, rub in with finger or with brush to "smudge" it onto the scalp. Do this before it dries.
Once dry, Rootz does not rub off or come off with sweat, wind or rain. Rootz is waterproof.

The Boost N Blend™ hair fibre applicator is an easy way to control and refine the distribution of hair fibres along your hairline, around your temples and along your part-line.

It will help to reduce mess and minimise the risk of wasted fibres. This handy pack allows you to purchase one 25g bottle of Boost N Blend™ Female Hair Fibres with our brand new spray applicator. 

Select your colour hair fibres from the drop down menu above before adding this product to your cart to ensure that you get the right colour fibres for your hair. 

The applicator is simple and easy to use:
1. Unpack and assemble applicator (you will need to screw the nozzle onto the end of the applicator and remove the cap).

2. Remove the internal lid/sieve of the Boost N Blend™ 25g Bottle. 

3. Screw the applicator to the top of the 25g Boost N Blend™ Bottle. 

4. Depress the top of the applicator to pump fibres onto your hair. 

5. Use the applicator strategically to maximise coverage and fibre placement. 

Boost N Blend is made from cotton, is vegan friendly with not a single animal product in sight (unlike most of the other hair fibre products on the market).

INGREDIENTS: cellulose (cotton) 95%, sodium sulfate, aluminium silicate, contains traces of ammonium chloride, mineral based colour.

If you are concerned in any way about these ingredients, let us reassure you...
The soldium sulfate is required to keep the fibres from taking in moisture. We use 2.4% which is half a gram (0.017 ounces) per bottle. 
Each bottle has approximately 70-100 applications in it so the amount on the hair at any given time is absolutely negligible.

The aluminium silicate is used for weight. In order to imitate the lightness of hair, our revolutionary fibers are extremely light and so to ensure they have a little weight in them to get from the bottle to the hair, a small amount (0.02%) is added. This too is an extremely small, almost negligible amount.

Our hair fibre products are designed to cling to the hair, so while a tiny amount may get through to the scalp, the main bulk of the product clings to the hair shaft, making it purely a topical application – that 
is, nothing is absorbed or ingested.

The other hair fibers on the market claim to be made of keratin, which means they are derived from either animal products or chemicals. If animal origin then they have a huge exposure to chemicals of many different kinds to render the animal products safe for humans. Otherwise keratin (as is claimed in many so-called keratin hair care products) is made purely from chemicals.

We say that our products are natural because they are 95% cotton – many cotton garments have less cotton in them than that. We do not have a long list of chemicals and what we do use is absolutely minimal. The keratin hair fibers cause itching and are well known for that. Our cotton fibres do not.

Also please note that we do state on the box and the bottle, for your safety, that the product should not be inhaled. It is best not to inhale anything that is designed to be used as a topical treatment (on the outside of the body).

before & after

Dusky Dark Brown Boost N Blend Hair Fibres Before and After

I bought Boost n Blend a few weeks ago and I just had to tell you that I am really impressed with it. It is an excellent product and it has worked wonders on the crown of my head where I had a very thin patch! Thank you!


Light Grey Boost N Blend Hair Fibres Before and After

Just wanted to say that this product is fabulous. My hair grew back after chemo but is thin on top. Pink scalp showed through the thin gray hair. To my surprise, application of your product virtually eliminated the view. It also stays in very well and there is no mess. Good Job


Smooth Medium Brown Boost N Blend Hair Fibres Before and After

Very happy with product, currently using the dark brown. Boost N Blend certainly does a lot for my confidence. Feel I can go out in the sunshine and my bare scalp is not so obvious. Will continue to use Boost.

    Great product but poor case quality

    I love the powder and will continue to use it. However both the case hinge and the brush came apart in the first use. I'm making do but some quality control might be needed in case this isn't a one-off issue.

    Hi Lisa, We are sorry to hear that the case and brush have come apart. This is definitely a one off as far as we know. But we would be happy to replace it free of charge.

    Brilliant product

    This product is ideal for filling in thin areas near the face where it can be difficult to apply the BoostnBlend fibres. Wish they made it in a grey option to match the grey fibres!

Instant hair loss concealer
What makes Boost N Blend different?
Most of the hair fibre products on the market today are made from keratin, however Boost N Blend™ is made from cotton, a natural occurring substance that we wear next to our skin every day.

Unlike keratin fibres, Boost N Blend is vegan friendly, being made from the cotton plant. This ensures Boost N Blend™ is less likely to irritate and clings super well to fine hair giving great coverage.

Some of our ladies find they wash their hair less often as it soaks up oils, acting like a dry shampoo, as well as providing a greater volume boost. We trialled both keratin and cotton fibres over two years and found the cotton to be a far superior product.
