When treating brunette hair, what is the advised limit for lightening?

When treating brunette hair, the advised limit for lightening is to achieve not more than two levels above the natural color. This guideline is essential for maintaining the integrity and health of the hair while achieving the desired aesthetic results.

Lightening hair beyond this two-level limit can cause excessive damage, especially for darker hair types, which are typically more susceptible to undue stress from chemical treatments. Two levels of lightening allows for a noticeable change in color while still ensuring that the overall structure and robustness of the hair remain intact.

In practical application, staying within this recommended limit helps prevent issues such as unwanted brassy tones, uneven color results, and a compromised hair texture. This approach also aligns with best practices in hair coloring, which prioritize the health of the hair and the satisfaction of the client.
