Hair Guru London Hair Thickening Fibres - 28g - Dark Blonde

Yes, apply your styling gels or mousses first and let them dry completely before shaking on the fibres.

The fibres are designed to bind to hair, but it is recommended to brush off any loose fibres from your hairline before getting dressed.

Longevity depends on the frequency of use and the size of the area being covered, but most users find a bottle lasts several weeks with daily application.

The cotton-based formula is generally gentle, but if you have a history of scalp sensitivity, perform a patch test first.

No, these fibres require existing hair strands to latch onto to provide coverage.

They are resistant to sweat, wind, and light rain, but they are not waterproof and will wash out easily in the shower with shampoo.

Ensure your hair is completely dry before application and consider using a light-hold styling spray to lock the fibres in place.

Try blending two close shades in the palm of your hand before application to create a custom color match.

Shake the container more gently or use a wider-tooth comb to lightly distribute the fibres after they land on your hair.
