L'Oréal Professionnel Dia Light Acidic Demi-Permanent Hair Color 1.7 oz is a professional ammonia-free hair color designed to tone, gloss, and refresh previously color-treated or sensitized hair. Featuring an acidic color technology, Dia Light helps deliver beautiful, luminous results while maintaining a smooth, glossy finish without lifting the natural hair color.
Ideal for toning highlighted, bleached, and pre-lightened hair, L'Oréal Dia Light offers a versatile range of shades for neutralizing unwanted tones, refreshing faded color, and creating customized salon-quality glossing services. Its gentle acidic formula is particularly suited for hair that has undergone previous chemical services.
Dia Light provides translucent, natural-looking color results while enhancing shine and improving the appearance of dull, faded hair. Its no-lift color technology makes it an excellent choice for refreshing lengths and ends, toning blondes, and creating subtle tonal adjustments without the commitment of permanent hair color.
This listing features the original 1.7 oz / 50 mL Dia Light packaging, ideal for customers seeking the older professional color range rather than the newer 2 oz version.
