2. Standard Ratio
The standard 1:1 ratio serves as a foundational principle in determining the appropriate amount of 20 volume developer to mix with hair color. This ratio signifies equal parts developer and color, creating a balanced chemical reaction essential for predictable color outcomes. This balance ensures sufficient lift and deposit of color molecules without over-processing. Deviation from this standard ratio can significantly impact the final color result. Using more developer than color can lead to excessive lightening, potentially resulting in brassiness, unwanted warmth, or hair damage. Conversely, using less developer might result in insufficient lift, yielding a darker result than anticipated or inadequate gray coverage.
Consider a scenario where one aims to achieve a medium brown shade. Using a 1:1 ratio with 20 volume developer provides the necessary lift to deposit the brown pigment while maintaining underlying tones. However, if a 1:2 ratio (one part color to two parts developer) were used, the higher concentration of peroxide could lift the hair beyond the desired level, potentially resulting in a lighter brown or even a reddish hue. Conversely, a 2:1 ratio might not lift the hair sufficiently, leaving the color too dark or uneven. These examples illustrate the practical significance of the 1:1 ratio in achieving desired color results. While professional stylists may adjust this ratio based on specific hair characteristics and desired outcomes, understanding the standard ratio is critical for achieving predictable and balanced results at home.
