When your stylist tells you what products to buy from their salon don’t just assume its to squeeze more money out of you. It’s to protect their work and make sure your hair looks good and remains healthy. It is a reputation of their work after all and want it to look good so people will see.
If you want your hair to look as good as it did that day, why would you use different products and try to achieve the same thing?
Also, for people who say I can get it cheaper at target, Walmart, etc…. You are not getting the same thing. Yes, it’s the same product but it’s expired. Companies sell to those store all the overflow that wasn’t bought and just sat on the shelf forever. And yes, product expires then makes your hair dry and lifeless.
Trust your stylist and if you don’t, find a new one.
