I booked an appointment for HD brows and was really disappointed when the therapist said the tint they used didn't cover grey. I've never encountered a salon that doesn't use grey-covering tint.
The therapist used a basic brow powder in the end but that's not what I went for.
That isn't the therapists fault, though. More concerning was the therapists rough treatment of the skin around my eyes. She was working very fast and dragging skin as well as catching my skin afew times in the tweezers.
