Sorry to hear that you've not had a great experience. I would speak to your salon and see if they can help rectify that for you. As they should.
The cost of products, wages, rates, overheads, rent, ppe, training costs to plug gaps, refreshments, magazines, WiFi, computer system costs, bank fees and transaction charges etc have risen substantially. The margin for profit has diminished hugely. Also, when you visit a professional you are also paying for their time and expertise.
Any decent stylist will try and up sell or add on treatments. They do help maintain and treat the hair. Also, stylists will make commission off of these products. (hopefully) but they should be quoting you every step of the way so there are no hidden surprises.
Personally, I confirm every step with my clients before service begins and throughout and if someone says that they can not afford it I always offer alternatives. This should hopefully be happening across the board.
Most stylists are on a minimum wage basic pay and earn their wages through commission. It's hard to do that with out clients coming in.
