They want to sell you a haircut and goop to put on your hair. Have them show you some hair that is in good condition.
If your hair is really in good condition, and your hair dresser is female maybe she is jealous, or maybe just pumping product. I would get a second opinion somewhere else.
They want to sell you something, to me it sounds like you need to find a new hairdresser.
doesnt always mean that its healthy. do you use products in your hair and blowdry it often?
Some products put a lot of build up on your hair... (IDK) just an example but: A hairdresser friend of mine would take up some of your hair, and run her scissors down the hair and all this buildup would accumulate on the scissors specifically from Panteen products??? who knows.. maybe she just wants to sell you a conditioning treatment or more products ??
Its crying for help lol
