My old boss in Fresno told me to always finish with a cold rinse, and 8 years later I still do it
He said it closes the cuticle and keeps the hair from looking frizzy, and honestly my clients notice the shine difference when I skip it. I tried dropping it for a busy Saturday to save 2 minutes per head and got two complaints about flyaways by noon. Does anyone else still do the cold rinse, or did you switch to a tonic instead?
