This lady came in with her face stained green from a homemade clay mask. She thought it was a disaster and almost cried. I got her to relax and we laughed about it while I fixed her skin. After a calming treatment, her complexion was glowing and she was so grateful. Now she tells all her friends about my salon.
I figured if they knew what they wanted, it was fine to just do the treatment. But a client with rosacea had a major flare-up after I caved. Now I never start without a full skin check first.
