For anyone mixing hair color and developer, whether a professional colorist in a salon setting or someone doing an at-home color application.

The built-in graduated markings are the real value here — they take the guesswork out of a color-to-developer ratio compared to eyeballing it in a plain bowl.

Pour color and developer into the bowl using the graduated markings for the correct ratio, and mix with a tint brush. Rinse and wash after use.

Pros:

• Graduated markings help measure accurate color-to-developer ratios
• No-slip base keeps it stable while mixing with a tint brush
• Reusable clear plastic, easy to see when color is fully blended

Cons:

• Dark tints can stain the plastic over repeated use
• Not heat-resistant — avoid hot water when cleaning
• Fixed 6oz size may be too small for larger, multi-application color jobs
