Many of the garments that are produced use residual dyes, hazardous chemicals, heavy metals, microfibers, and mordants to help bond dyes with fabric. Many of these synthetic dyes, specifically azo dyes, are carcinogenic. Azo dyes are water-soluble making them easy for skin to absorb and, as a result, may cause skin and eye irritation. Even though most countries have banned these toxic dyes, there are still parts of the world that still use these in production to support the high demand of fast fashion. Many countries can’t access clean drinking or bathing water because of the contamination caused by harmful dyes.
