Which volume is typically used for significant lightening in hair coloring?

The volume used for significant lightening in hair coloring is typically 40 volume. This is because 40 volume developer contains a higher concentration of hydrogen peroxide (12% to 13%) which allows for a more aggressive lifting effect on the hair. When clients desire to achieve a lighter shade, especially when transitioning from dark to very light colors, using a higher volume developer facilitates the necessary chemical process to lift the natural pigment effectively.

In practical applications, 40 volume developer is often employed in situations where maximum lift is required, such as for highlights or when attempting to achieve a platinum blonde look. It is essential for stylists to use this volume with caution, as it can potentially cause hair damage if not used correctly or if the hair is not in good condition.

Lower volumes, like 10 and 20, are generally better suited for tonal adjustments or when only slight lifting is needed. These developers are less potent and provide milder lightening effects, making them appropriate for more subtle coloring techniques. 30 volume developer can offer significant lift as well, but 40 volume is specifically recognized for achieving the maximum lightening achievable in one process.
