Pricing Color Correction Services

Has this scenario happened to you? Your client has a level 4 hair, when she booked the service she booked for a root retouch and some partial foils in between of a level 6 caramel. 20 mins before the appointment she texts a picture of a level 10 ashy balayage, with a level 7 ash as the base. You personally would love to do this on her so you say YES that’s amazing we should do that!
