The Kerrato Hair Fibre Applicator Pump is an essential tool for targeting thinning hair, bald patches, and wide parts. Rather than shaking fibers directly onto the scalp—which can lead to clumping and mess—this pump-nozzle system disperses the keratin fibers uniformly. It is particularly effective for shaping a highly natural-looking frontal hairline when paired with an optimizer comb. This reusable, smart pump helps minimize product waste, making your fiber application cleaner, more efficient, and incredibly economical.
