The first salon I ever trained in was back to back and we had to be quick. 30mins for a full manicure, 30mins for full leg+bik wax etc. So I just had to learn to be really efficient. If I knew the client was the type to faff around putting make up etc on after a facial, then I would have to cut their treatment down slightly because I knew I had to take the next lady literally straight in.
To help me be more efficient I would plan my day, and anticipate what was next. I would generally strip the bed/ change bed roll whilst my client was getting dressed so that my room was ready for the next person to come straight in,and I would make sure at the start of the day that I had everything topped up- cotton wool, spatulas, strips, full facial products etc. I had some lovely relationships with clients, but I did feel it was always a rush. We had 5 mins for lunch if we were lucky, and my bladder had to get used to holding it unfortunately (now I have problems from no food and unnaturally holding my bladder :sad
Anyway, the above I think was down to a bad salon owner of a huge organisation who always want to milk you of every last drop of energy!
Now I work for myself from home and make sure that clients have a relaxed time after their treatment. Usually allow 15mins between clients, but bit longer if they've had a relaxing treatment. So lovely being your own boss.
