Q1: How long does the hair color shampoo last?
This is a semi-permanent hair color shampoo, which typically lasts for up to 4-6 weeks depending on washing frequency, hair care routine, and individual hair condition.
Q2: Do I need to mix this shampoo with a developer or dioxygen?
No mixing is required. It can be applied directly to bleached hair. You do not need to add any developer or dioxygen, making the process exceptionally easy and safe.
Q3: Will this product stain my hands and scalp?
Our advanced formula is specifically designed to color hair without staining the hands and scalp. However, we recommend using protective gloves during application for optimal cleanliness and sensitivity precautions.
Q4: Can I get vibrant colors on dark, unbleached hair?
For the best and most vivid color payoff, it is recommended to apply this hair color shampoo to bleached or lightened hair. The colors will appear much more vibrant and true to shade on lighter bases.
Q5: What are the available colors, and is custom formula possible?
We offer 20 kinds of standard colors. We also provide full OEM/ODM support, meaning your custom cream colors, formulas, and labels can be designed and manufactured by our experienced R&D team.
Q6: How long should I leave the shampoo on my hair to get the color?
Generally, the shampoo works fast. Leaving it on for 10 to 20 minutes before rinsing will allow you to achieve a beautiful, even color distribution. Adjust the time depending on your target color intensity.
