The next generation in Ammonia, PPD and Resorcinol-free professional hair coloring.
Ammonia a is typically used to swell the hair and open the cuticle scales to allow color to penetrate deep within the cortex. Yes, for anyone with sensitive skin or scalp, this could be an unhealthy additive. They’ve replaced it with MEA. MEA is an alkalizing agent that mimics the role of Ammonia, minus the odor, irritation, and cuticle damage.
PPD (Paraphenylenediamine) is a chemical know to cause dermatitis, reddening and swelling of the scalp and face. They’ve replaced it with low levels of PTDS (p-Toluendiamine Sulfate). PRDS enables up to 50% of PPD allergic stylists and clients to now use this coloring system.
Resorcinol is a popular coloring agent toxic to wildlife and the human immune system. Shade dependent, they’ve replaced it with 2-Methylresorcinol or 4-Chlororesorcinol . The two chemicals are kinder to the environment and promote less potential to sensitize.
