If a client’s brown hair has taken on a greenish hue, one way to rectify this is by using Dia Richesse in shades 6.34 or 6.40. These shades can help neutralize the unwanted green tone and restore a more natural brown shade to the hair.
When selecting the peroxide or developer for this process, it’s advisable to keep it at a lower volume to deposit the colour effectively. Additionally, consider the porosity of the hair to ensure an even and desired result.
