The specific formulas come from countless tests and years of polling black and grey specific artists to gather a commonality in ratios for the perfect 4 bottle set. We use the purest hospital-grade water, which is filtered, distilled and UV sterilized in our facility, to ensure the #00 Mixing Solution in our washes is at the utmost purity and held to the highest standard. The addition of witch hazel to this solution not only adds a visible smoothness to your work but also brings a soothing quality and feeling to your clients.

Includes:

#40- A smooth light-mid tone wash.
