Each of these chemicals may cause problems, from drying hair out, to leaving it brittle and prone to breakage.
They actually do this working as a team. Ammonia allows the dye to penetrate the shaft of your hair by swelling it and lifting hair cuticles, the protective plates that cover hair. Hydrogen peroxide destroys your hair’s natural color, while also drying it out.
The chemicals also strip away hair’s natural protective lipid layer, leaving it exposed to future damage and feeling rougher
Dyes used as color additives bring their own challenges. Sensitizers such as PPDA in particular are known as a common allergens.
Combined, these ingredients can be very damaging indeed, even causing hair loss due to breakage over time.
