Dia Light Demi-Permanent Hair Color 50ml is an ammonia-free, tone-on-tone professional hair color designed for gentle color enhancement and tonal correction. It uses an acidic technology to deposit color without lifting the natural base, helping maintain hair condition and surface shine.
Suitable for sensitized or previously colored hair, Dia Light is commonly used for glossing, refreshing faded lengths, neutralizing unwanted tones, and blending early greys. The 50ml tube is mixed with the dedicated Diactivateur developer to ensure controlled, even color results and gradual fade over time.
