Key Benefits

Intense Frizz & Curl Straightening: Delivers instant, dramatic straightening results on textured, wavy, curly, and frizzy hair.
- Deep Structural Hair Repair: Keratin replaces up to 90% of lost hair proteins, eliminating split ends and repairing damage from chemical processing or coloring.
- Custom Strength Options: Available in four tailored concentrations (0%, 5%, 8%, and 12%) so you get the exact smoothing power required for your specific curl pattern.
- Long-Lasting Gloss & Softness: Seals the hair surface against moisture and humidity, maintaining sleek shine through routine washes.
How to Choose Your Keratin Strength
- 0% Formalin: Ideal for light frizz control, damaged/bleached strands, or sensitized fine hair.
- 5% Keratin: Ideal for soft waves, mild volume, and standard frizz repair.
- 8% Keratin: Ideal for thick waves, defined curls, and coarse hair textures.
- 12% Keratin: Maximum strength for very thick, coarse, resistant, or tight coil patterns.
Step-by-Step Application Guide
- Step 1 (Clarify): Wash hair twice with the Purifying Shampoo (300ml) to strip away styling residue, sebum, and open cuticles for optimal absorption. Blow-dry hair completely.
- Step 2 (Apply Treatment): Section hair and apply the PURC Keratin Treatment (1000ml) evenly using a tint brush and fine-tooth comb. Comb out excess product so hair is damp, not dripping.
- Step 3 (Absorb & Blow Dry): Let the treatment absorb into the hair for 20–30 minutes, then blow-dry hair straight using medium heat.
- Step 4 (Seal with Flat Iron): Flat iron small, 1-inch sections 5 to 7 times at 210°C–230°C (410°F–450°F) to lock the keratin into each strand.

How to Use
1. Wash twice on chemically-treated hair and third on virgin hair with PURC Purifying Shampoo. Blow hair to 100% dry.
2. Comb through every section until hair is completely saturated. Shake the bottle well and pour approximately 2-3 oz of Keratin Treatment into bowl. Wear gloves and apply to hair with brush.
3. Place hair in cap. For chemically-treated or damaged hair, allow hair to absorb solution for 20 minutes; for very resistant, coarse hair, allow hair to absorb solution for 30 minutes. Then blow hair to 100% dry.
4. Divide hair into 4 sections with a heat resistant comb. Using a 450°F (230°C) flat iron, start at the nape of your neck, taking 1/8 inch sections. Slowly move the iron from root to ends 5-7 times (7-10 times for extremely curly coarse hair) to infuse the keratin into the hair shaft. For chemically treated damaged hair lower heat to 430°(200°C).
5. After 3 days, wash hair with PURC After-treatment Shampoo and Conditioner. (or the other shampoo does not contain Sodium Chloride).
