The PURC Disulfide Bond Hair Mask goes deeper — its patented Silsoft™ AX fluid and hydrolyzed keratin formula targets all 10 levels of hair damage, rebuilding the internal hair structure by reconnecting broken disulfide bonds. The result is genuinely stronger, more resilient hair rather than just a temporary smoothing effect.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is this keratin hair mask suitable for all hair types?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! The PURC Disulfide Bond Reductive Hair Mask is formulated for all hair types — straight, wavy, curly, or coily — and is unisex.

Apply it to semi-damp hair \u003cem\u003ebefore\u003c\/em\u003e shampooing. This allows the keratin and Silsoft™ AX fluid to penetrate the hair core and carry out the disulfide bond repair process before cleansing begins. Using it after shampooing is not recommended as the formula works best as a preparatory step.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How long do I leave the PURC Keratin Hair Mask on?\u003c\/h4\u003e\n\u003cp\u003eA: Leave the mask on for a minimum of 5 minutes and up to 30 minutes, depending on your preference and the level of restoration your hair needs.
