Hairdressing question

[HairHereThere]

Is shampoo conditioner hair washing a part of the treatment that is included in the cost or is it complimentary?
It takes about 5-10 mins usually and uses the salons products but do you actually factor that in to the price of the cut colour blow dry treatment ?

It seems that places like super cuts charge on a step my step basis I.e I had my hair straightened for a £5 on top of my cut but other salons it’s all in the cost of the cut colour blow dry
