My post wasn't aimed at you Fake it. I have no doubt your service isn't anything other than top class. I work inmy own home salon and I am not under the same pressures that some who work at busy salons are under. That isn't to say I am not busy, fortunatley I am.
If I have a new client who has clear natural nails I allow an hour for Shellac, for the initial consultation and then the treatment and then the after care and then clean up after they have left, so not too disimilar to what you do.
My regular clients usually have Shellac, Gelish or Gelcolor on their nails so I allow 20 minutes to remove and I use that time to make them a cup of tea, let them choose their next colour and fill out their card. It then takes me around half an hour to do a plale colour and a little longer for a dark colour or a French. My clients like to have a chat so they do tend to stay a bit longer.
To do either of the above with Gelish or Gelcolor the time is reduced because of the LED light so a new application on clear nails would take a shorter time as they would if they had it removed prior to a new application. If they want a full manicure, which a lot do, then that would add another 20 minutes.
As for L&P I allow anything from 70 minutes to 90 minutes depending on the clients and what you are doing, plus a lot of my clients who have extensions have Shellac, Gelish or OPI over the top.
It boils down to a number of things I guess, experience certainly counts but there are all sorts of variables. There is no way I would be doing 8 sets of extensions or 16 overlays in an 8 hour day and I am shocked some salons do this.
To conclude, if you are happy with what you do and so are your clients then you will be doing it right.
