What are the different categorisation of Beauty parlors, spa, salons, wellness centres?

I was wondering if there already is a formal %26amp; systematic way of grading beauty parlours, based on the services they offer, prices they charge, and infra-structure they have eg: seating, sauna, massage, bridal make up.....What are the different categorisation of Beauty parlors, spa, salons, wellness centres?
I AM NOT SURE, WHETHER, THEY HAVE PROPERLY NAMED IT IN INDIA. BUT, THE ACTUAL MEANINGS ARE:


1) Beauty Parlours - FACIAL %26amp; COIFFING.


2) Spa - MASSAGE PARLOURS WITH STEAM BATH, ETC.


3) Salons - HAIR STYLING


4) Wellness Centers - ETHINIC HEALTH IMPROVEMENT CENTERS - LIKE HERBAL OIL MASSAGE, ETC.What are the different categorisation of Beauty parlors, spa, salons, wellness centres?
Two doors,


1 Leads into the beauty parlour


1 leads back to the street.


The sign says Gullible above the one that leads into the beauty parlour.
