Frequently Asked Questions

Q: How long does the black color from this hair dye shampoo last?

A: The color is designed to be long-lasting with regular use. Results can vary based on hair type, porosity, and how often you wash your hair. Using the shampoo consistently as part of your routine helps build and maintain deeper, richer color over time.

Q: Will this black hair dye shampoo stain my scalp?

A: The REAROYA Black Hair Dye Shampoo is specifically formulated to minimize scalp staining. The plant-based formula is designed to adhere to the hair strand rather than the scalp. For best results, follow the usage instructions carefully.

Q: Is this hair dye shampoo suitable for grey or white hair?

A: Yes — the black shade is effective at covering grey and white hair. For lighter shades like dark coffee or dark red wine, those are especially suited to grey/white hair and produce brighter color the more grey hair is present. Brown and lighter shades work better on naturally dark hair without grey coverage.

Q: Can I use this product if I have previously dyed my hair?

A: It depends on the previous dye used. If your hair has been coated with an oil-based black dye, a color removal step may be needed before achieving optimal results with a new shade. The black shade works well over most previously dark-dyed hair to refresh and deepen the color.
