Important Color Notes

• Hair previously dyed dark or treated with black oil may need to be lightened first before a new color can take effect.
• Brown and burgundy shades are best suited for natural (undyed) dark hair and cannot cover white/gray hair.
• Dark coffee and wine-red shades are designed specifically for gray or white hair — the more white hair you have, the more vibrant the result.

Frequently Asked Questions

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

A: With regular use, the REAROYA Black Hair Dye Shampoo delivers long-lasting black color. Results may vary based on hair type, porosity, and how often you wash your hair. Reapplying every few washes helps maintain color depth and vibrancy.

Q: Will the black shampoo stain my scalp or skin?

A: This formula is specifically designed to color hair strands without staining the scalp. However, we recommend rinsing promptly after the processing time and applying a small amount of barrier cream around your hairline if you have sensitive skin.

Q: Is this black hair dye shampoo safe for all hair types?

A: Yes — the REAROYA plant-based formula is suitable for all hair types and is free from high-concern chemicals, making it a gentler alternative to traditional chemical dyes. It is unisex and can be used by both men and women.

Q: Why didn't my hair color after using the shampoo?

A: Common reasons include uneven application, too short a processing time (especially in cold weather or with thick/coarse hair), or internal mixing of the two reagents during transit. Always follow the included instructions carefully and ensure both components are dispensed evenly for best results.
