TLDR Natural hair dyes are safer but have limited shades and may fade with washing.
The document discusses the development and evaluation of natural hair dye formulations as an alternative to synthetic oxidative dyes, which pose health and environmental risks. Natural dyes, derived from plants like henna, indigo, and beetroot, primarily coat the hair surface and are generally safer, exhibiting near-neutral pH, low ash content, and minimal irritation in tests. However, they face challenges such as limited shade range, application consistency, and fading with shampooing. Some commercial products may be adulterated with synthetic additives, affecting safety perceptions. The review highlights the need for standardization and improved delivery systems to enhance consumer acceptance.
