Hello, I would like to enquire about hair colouring or highlights in Berlin. My current colour, length and previous colouring or chemical treatments are [details], the reference photo is [photo], and the areas I want to change are [full head, selected areas, face-framing strands, etc.]. Please assess whether you can arrange this and explain the proposed coverage and steps. State separately whether toning, treatment, cutting and blow-drying or styling are included. If several visits are needed, list the work and cost for each. Please explain how length, product usage or working time affect the estimate, whether a consultation is needed and its fee, and identify unresolved items and how additional charges are approved. This is an enquiry, not an appointment.
