L'Oréal INOA ODS Oxydant Riche 20 Vol 6% Developer is a 20 volume (6%) cream developer specifically formulated for use with the INOA ammonia-free permanent hair color line and its patented ODS (Oil Delivery System) technology. It provides controlled lightening of up to 2 levels and is ideal for grey and white hair coverage services.
