For best results we suggest that you only wear Firozé nail polishes. Do not wear any other nail polish, as our polishes are the only nail products free of Dibutyl Phthalate, Toluene and Formaldehyde with Tea tree Oil, Horsetail Extract and Vitamin B12, enhanced with protein & Calcium. If you are a new user, we recommend using this protein-enriched Nail Rejuvenating & cuticle Cream at least 3-4 times daily. Continue applying the Firozé Silk Enhancer to the nails as directed.
