KNF Wheat and Silk Ampoule. Due to its combination of wheat protein and silk, it is recommended for all hair types, especially for chemically treated hair, thanks to its hygroscopic properties (ability to absorb water). It hydrates dry hair, is lightweight, and its micro molecules penetrate the hair fiber, keeping the hair silky and hydrated. USAGE: Apply to damp hair, leaving 3 cm from the roots. Apply to the ends, do not rinse, and style as usual.
