Keratin Strength Guide – Choose Your Formula

PURC Brazilian Keratin is available in four formalin concentrations so you can match the formula to your hair's needs:

• 0% (Formaldehyde-Free): Ideal for lightly wavy or minimally stressed hair
• 5% Formalin: Best for normal curly or moderately conditioned hair (recommended for Asia, Middle East, Europe, Russia)
• 8% Formalin: Designed for deep curls or more conditioned hair (recommended for Africa, South America, and stronger curl patterns)
• 12% Formalin: Maximum strength for very tight curls or heavily conditioned hair

⚠️ Notice: Use in a well-ventilated area or wear a mask during application due to the product's strong scent. If your hair is naturally golden/blonde, avoid the formaldehyde-free version to prevent color shift — choose 5% formalin or higher instead. If your hair is longer than 17 inches, we recommend purchasing 2 sets.
