Even the cheapest shampoo can perform its job, to clean pollution. If your hair is damaged, throw away your tools, shampoo after shampoo no matter what brand is not going to improve it.
DYK the hair industry is a billion dollar business? Their job is to make promises, say anything so we could buy buy buy and for them to sell sell sell so they can build another mansion in a secluded island somewhere and to buy Lamborghini for their collection?
It's called marketing. Even the cheapest shampoo does its job, to clean the pollution. You don't even need conditioner, unless you live in a hard water area (lucky me), if your hair is permed, dyed, straightened. The majority of hair problems here are from girls in their 30s, asking how to care for their damaged hair, what product to make their hair grow, why their hair falls out, and why their shampoo or conditioner don't work. And they're giving advice here?
As you've already experienced, because someone here told you to use biolage.
Trim the damage ends, to allow new growth to develop. Use bottled water for the last rinse, to create softness if you live in hard water.

I know hair. I have silky, shiny, stick straight healthy hair, previously damaged by perming & dyeing. I'm older and I know better now.
