Toning brown hair, a process that involves applying a semi-permanent or permanent color to brown hair, can enhance its depth and richness. For instance, adding cool tones to brown hair can neutralize unwanted brassiness or warmth.
Toning brown hair has become increasingly popular due to its versatility and affordability. It provides a subtle way to refresh and revitalize hair color without resorting to drastic changes. Moreover, toning can be used to correct color imbalances, add shine, and even disguise gray hairs. The technique has roots in ancient times, with civilizations such as the Egyptians and Romans using natural ingredients like henna and vinegar to enhance their hair color.
