A bioactive ingredient that reinforces keratin, maintains moisture, and protects dyed hair color under extreme thermal and chemical stress in all hair types.
A multifunctional ingredient with dual action on the hair surface and within the hair fiber driven by hydrolyzed proteins, polyphenols and serine.
An upcycling active ingredient from locally sourced barley malt rootlets.
Kromboost™ is an upcycled active ingredient based on hydrolyzed barley protein rich in peptides, polyphenols and enhanced with serine. Designed to reduce heat damage while helping to preserve hair color, maintain hydration, and improve hair strength.
It is derived from upcycled barley malt rootlets generated during the craft beer brewing process, sourced from Lo Vilot, a local supplier located just a few kilometers from Provital’s facilities.
Through Provital’s proprietary, optimized enzyme‑assisted process, peptides and polyphenols are obtained. The composition is further enriched with serine, a key amino acid in hair keratin, recognized for its excellent moisture‑retention properties.
