Tressa Watercolors Base Drops - Red is a salon-focused color refresher designed to be mixed into hair color or used as a standalone additive for customizing red tones. The concentrated drop format allows precise adjustment of color intensity without altering the developer or base shade. It comes in a 4 oz bottle that is easy to dispense and store between appointments.

This unisex product is suitable for professional and at-home color maintenance, helping refresh or intensify red hues while supporting a healthy-looking finish. The liquid base blends smoothly into color formulations, making it simple to control the final result. It is intended for users who want flexible, buildable color without committing to a full re-color service.

For best results, add the desired number of drops to your color bowl or conditioner, mix thoroughly, and apply evenly to clean, towel-dried hair. Follow the instructions provided with your color service and perform a patch test before use. Store tightly closed in a cool, dry place away from direct sunlight.
