While many products have advertised low ammonia formulations there has never been a credible hair color solution that bypasses the use of ammonia entirely until now. Organic Color Systems guarantees long lasting ammonia free colors.
As a result of research and exacting technical instructions a broad range of hair color results are obtainable. OCS is in a form that is nontoxic, predictable, causes no scalp or skin staining, and preserves the life, richness, and shine of hair. OCS' staying power is greater than ammonia and ammonia-substitute based alternatives; the fade factor is virtually eliminated, and it covers grey beautifully.
