DR RASHEL COLLAGEN AND ARGAN OIL HAIR COLOUR SHAMPOO (NATURAL BLACK) 400ML

Key benefits & ingredients • Dual action (2-in-1 / 3-in-1): it acts as a shampoo, permanent hair color, and deep conditioner. • Collagen infusion: fortifies the hair structure from root to tip, improving elasticity and reducing breakage. • Argan oil nourishment: deeply hydrates, repairs damaged cuticles, and restores a silky, natural shine. • Gentle formula: free from ammonia, making it less irritating and much gentler on the scalp than traditional chemical dyes How to use instructions To get the best result without staining your skin, follow the official protocol closely: 1. Perform a patch test: apply a small amount behind your ear 48 hours before full use to verify skin compatibility. 2. Prepare: ensure your hair is dry before starting. Put on protective waterproof gloves to avoid skin or nail staining. 3. Dispense & mix: press the pump down firmly until both color agents discharge. Mix the formula thoroughly in your gloved hands. 4. Apply & massage: work it evenly through your dry hair, massaging gently until it acts like a rich lather. 5. Wait time: leave it on for 5 to 10 minutes. Note: if you have exceptionally thick, coarse, or resistant hair, you can extend the time to 15–20 minutes. 6. Rinse: rinse completely with warm water and blow-dry.
