Will it look fake?

Not if you match the shade and start light. The fibres are cut short enough to behave like strands rather than powder, so they catch the light the way hair does. Build up in thin layers until it looks right, rather than emptying the bottle in one go.

Product details

Densifol is a bottle of pure keratin hair building fibres. Shake over the thinning area, press in with your fingertips, and the fibres cling to your own hair for instant, natural looking coverage. Holds through rain, sweat and a full day, and washes out with normal shampoo.

The routine

Here's how Densifol works

Thirty seconds, start to finish. Shake, press, done.

1

Shake

Shake the bottle over the area you want to cover. The keratin fibres fall where you point them, and you will know your amount after a couple of goes.

2

Press

Press the fibres in with your fingertips. Static holds each fibre onto the hair already there, so it looks like hair and not like product.

3

Set

That is it. No setting spray, no waiting. Thirty seconds and the scalp show-through is gone.

4

Holds all day

It stays put through rain, sweat and a full shift. Drizzle, the gym, a hard hat on and off, it holds.

5

Washes out

Normal shampoo washes it out whenever you want it gone. Nothing to scrub, nothing left behind.

The founder

"I was a builder from Hull. I won on The Summit and put the winnings into building an honest hair fibre."

Shaun had thinning hair from his twenties and got tired of paying big-brand prices to cover it. So he built Densifol: the same keratin fibres, sold direct, at a price that is not taking the mick.

The mechanism

What is keratin

The same protein hair is made of. Here is how the fibres do the work.

What are keratin fibres?

Densifol is made of keratin, the same protein hair is made of. The fibres are cut to microscopic lengths, so they pour like a fine powder but cling and catch the light the way hair does rather than sitting flat like a pigment.

Why do they cling?

A light static charge makes each fibre grab onto the hair already there. Press them in and they lock, so the coverage moves and catches the light the way hair does.

Does it come off on its own?

No. It holds through rain, sweat and a full day. When you want it gone, normal shampoo washes it out. Nothing to scrub, nothing left behind.

Shade-match guarantee. Money-back guarantee.

Questions

Frequently asked questions

Why is Densifol cheaper than the big brands?

It sells direct, so there is no giant marketing budget or chain of middlemen baked into the price. Same keratin fibres, fair cost.

Does it hold through rain and sweat?

Yes. It holds on its own through a normal day, drizzle, sweat and the gym included. No setting spray needed, it stays put through a proper downpour or a double shift.

Will it stain a pillow?

Applied properly, no. The fibres bond to the hair and anything loose brushes off. It is made to be washed out at night rather than slept in.

What if the shade is wrong?

Tell us and we re-ship the right one free, nothing to post back. That is the shade-match guarantee, plain and simple.
