Why Your Hair Needs This

Hair is made up of approximately 90% keratin, held together by disulfide bonds. Everyday stressors — heat tools, UV exposure, chemical colouring, perming, and bleaching — break these bonds, leaving hair frizzy, brittle, tangled, and lifeless. Ordinary conditioners and masks only address surface-level or mild damage (levels 5–6). The PURC Disulfide Bond Hair Mask targets all 10 levels of damage, including the most severe (perm, dye, and bleach damage at levels 9–10).

Key Benefits

• Structural Restoration: Silsoft™ AX fluid reconnects broken disulfide bonds, rebuilding the hair core from within for stronger, more elastic strands.
• 3× Smoother Hair: Automatically detangles knots — easier wet and dry combing from the very first use.
• 12× Strengthened: Significantly improves breakage resistance and hair elasticity.
• Intensely Hydrated: 5% Aloe Vera keeps hair moisturised and reduces frizz-causing dryness by up to 98%.
• Brilliant Shine: 10% Jojoba Seed Oil seals the cuticle and enhances natural lustre.
• Reduced Shedding: Strengthened strands mean less hair lost during washing and styling.
• Split End Repair: Fills and seals split ends for a visibly healthier finish.

Key Ingredients

• Hydrolyzed Keratin: Low-molecular-weight keratin penetrates the hair core to repair internal structure — not just the surface.
• Silsoft™ AX Fluid (Patented): Bonds broken hair strands at both ends, seals them together, and fills gaps for a more secure, lasting repair.
• 10% Jojoba Seed Oil: Mimics the hair's natural sebum to deliver deep, lasting moisture and shine.
• 5% Aloe Vera: Soothes the hair fibre and locks in moisture to prevent dryness and frizz.

How to Use

Step 1: Wet your hair and gently pat until semi-damp.

Step 2: Apply an even amount of the hair mask throughout your hair, avoiding the scalp. Tie hair up or cover with a shower cap. Leave on for 5–30 minutes.

Step 3: Rinse thoroughly with plenty of water, then shampoo as usual.

Note: This is a pre-wash hair mask. Apply before shampooing for best results.

Frequently Asked Questions

Q: How is the PURC Keratin Hair Mask different from a regular conditioner or hair mask?

A: Regular conditioners and hair masks work primarily on the surface of the hair and can address mild to moderate damage (levels 5–6). 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.

Q: Is this keratin hair mask suitable for all hair types?

A: Yes! The PURC Disulfide Bond Reductive Hair Mask is formulated for all hair types — straight, wavy, curly, or coily — and is unisex. It is particularly beneficial for hair that has been exposed to heat tools, chemical treatments (perming, colouring, bleaching), sun damage, or general environmental stress.

Q: When should I apply the PURC hair mask — before or after shampooing?

A: This is a pre-wash treatment. Apply it to semi-damp hair before 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.

Q: How long do I leave the PURC Keratin Hair Mask on?

A: 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. You can adjust timing to fit your routine — even 5 minutes delivers noticeable improvements in smoothness, strength, and detangling.
