10 Vol

L'Oréal Professionnel INOA Rich Developer is a 10 volume (3%) cream developer specifically formulated for use with the INOA ammonia-free permanent hair color line, which features patented ODS (Oil Delivery System) technology . This professional-grade developer is designed for services requiring gentle color deposit with controlled lift of up to 1 level .

The rich, creamy formula mixes at a 1:1 ratio with INOA color (60ml color + 60ml developer) and provides up to 35 minutes of development time for optimal, long-lasting results . The 10 volume concentration is ideal for darkening a naturally light base color, performing tone-on-tone coloring, taking color through mid-lengths and ends, and for pre-coloration services .

Enriched with mineral oil and conditioning ingredients, this developer works in synergy with INOA's oil-based formula to preserve the hair's natural lipid content and protect the scalp during the coloring process . The result is vibrant, ammonia-free color with superior shine and optimal scalp comfort.

This product is intended for professional use only and is not for use on persons under 16 years of age . Always perform a patch test 48 hours before any coloring service. To use, mix with selected INOA shade at 1:1 ratio, apply to dry, unwashed hair, process for up to 35 minutes, then emulsify, rinse thoroughly, and follow with INOA post-color shampoo.
