Developer
A Developer in hairdressing is a professional who works with hair color chemicals and treatments. They are responsible for mixing and applying various chemical solutions that help create different hair effects, like lightening hair color or creating specific tones. The term "developer" comes from its role in "developing" or activating hair colors and treatments. It's often mentioned alongside terms like "peroxide" or "activator." When you see this term in a resume, it usually refers to someone who has experience handling these important hair processing chemicals safely and effectively.
