Yes, you can mix different colors of Rainbow Research Henna to create custom shades. However, it's recommended to test the mixture on a small strand of hair first.

While Rainbow Research Henna is natural, it's best to consult with a professional and perform a strand test if your hair has been chemically treated.

The amount of product needed depends on the length and thickness of your hair. A general guideline is to use 50-100 grams for short hair, 100-200 grams for medium-length hair, and 200+ grams for long hair.

Ensure you have followed the mixing and application instructions correctly. Longer processing times or multiple applications might be needed to achieve the desired intensity, especially on darker hair.

Make sure the henna mixture is applied evenly to your hair, from root to tip. Ensure that all hair strands are coated to prevent unevenness.

Adjust the water to powder ratio. Add more water to thin the mixture, or more powder to thicken it, to achieve a yogurt-like consistency.

Use a deep conditioning treatment after rinsing the henna. This will help moisturize your hair. Adding a small amount of oil to the henna mix can also help.
