Green Heads is an organic hairdressing chain founded by Maria Hellström, who owns and operates the brand’s three salons. In addition to Green Heads Birka, there are two other salons located at Södermalm and Östermalm. Treatments include haircuts, coloring, styling, extensions, hair care treatments, and balayage. The difference from a traditional salon is that all colors and products are completely free of toxic chemicals. Specifically, synthetic colors and natural plant colors are used.
