Bosley Hair Thickening Fibers – Black

Bosley Professional Hair Thickening Fibers blend with your natural hair to cover thinning and low-density areas for hair that’s instantly thicker and fuller.

Keratin fibers are a key structural component of your hair and nails. Charged with static electricity, they intertwine and bond with your own hair to cover up fine and thin areas.

Easy to apply, they are perfect for a cover-up between colour treatments and you simply shampoo your hair to remove.
