Depend Eyebrow Colour produces an intense colour in the eyebrows, emphasising their shape in a more pronounced way. New formula with rice protein and oil extracted from cuckoo flower reduces the treatment time and produces salon results. The hair colouring process is gentler — and the result is permanent and waterproof. Lasts up to 6 weeks. Choose between the colours black, brown black, dark brown and brown. Read through all the instructions and information on the allergy test before commencing colouring.
