Directions:
How to mix Hennalucent:
1. Pour Hennalucent into a plastic or glass bowl. Add very hot water, stirring constantly until blended to a smooth, honey-like consistency.
2. Let mixture sit a minute to stabilize. If it thickens, add more hot water. Mixture should remain creamy and moist during processing.
How to apply Hennalucent:
1. Apply HP3 Intensive Conditioner along the hairline and wear gloves with all shades except Neutral to avoid staining.
2. Apply Hennalucent to clean hair. If hair is very soiled or lacquered, shampoo and towel dry.
3. Use tint brush to apply Hennalucent generously to the parts, starting at the crown. Touch up the hair line last. Then gently work mixture through the hair, making sure all ends are saturated.
4. Wrap a cotton strip around hairline to prevent dripping. No cap or foil is needed. Do not use a hair dryer.
5. To determine the proper process time, see Hennalucent timing guide.
6. When desired results are reached, rinse hair thoroughly with warm water. Then shampoo with a mild shampoo.
