What to wash it out with

Every fiber brand washes out with shampoo, and nightly washing is part of the routine. We pair Nanogen with Regenepure DR with ketoconazole to keep the scalp clear of fungus under daily product use.

The best shampoo to use with hair fibers: Regenepure DR with ketoconazole

Fibers hide thinning; they don't treat it. Daily fiber users also wash every night, so the shampoo matters. Regenepure DR is the most effective hair loss shampoo to pair with any fiber brand. Its ketoconazole helps make sure scalp fungus and dandruff don't take hold under daily product use, and ketoconazole may help encourage growth. It washes fibers out cleanly, without harsh sulfates or parabens.
