  • "Great products, I use them every morning"

Is this product made for me?

If shaking your fibers leaves clumps on one side and nothing on the other, this is the fix.

  • You use Hair Fibers

  • You want to fill a specific spot, not your whole head

  • You want your fibers to look natural

How is it different from a regular shaker bottle?

A shaker bottle drops fibers wherever gravity wants. This puts them exactly where you aim.

Squeeze the bulb and the nozzle sends a fine, even layer of fibers right where you need it. No clumps, no patches, nobody knows.

  • Even. Fine layer, no clumps.

  • Precise. Aim at your temples, your crown or your beard.

  • Doesn't clog. Even with regular use.

  • Natural. Looks like hair, not product.

Short squeezes from close up and you add a little at a time. I was scared of puffing a black cloud onto my head, that doesn't happen. You stop when you can't see your scalp
