What is the most common type of hair color used in salons?

Permanent color is the most common type of hair color used in salons because it provides long-lasting results by penetrating the hair shaft and altering the natural pigments. This type of color allows for full coverage of gray hair and can lighten hair by several shades, making it a versatile choice for various hair coloring needs. It is ideal for clients who want to change their hair color dramatically or maintain their color over time without frequent touch-ups, as it does not wash out easily.

Many clients prefer permanent color because it allows for more consistent and vibrant results that endure through washes and time, while also offering a wide range of shades and formulations to cater to different hair types and desired outcomes. This effectiveness in achieving lasting results is why permanent color is the choice most frequently requested in professional salon settings.
