Have you ever watched your shampoo suds circling the plughole and wondered, is expensive shampoo better? Or, by treating ourselves to pricy luxury haircare are we literally pouring money down the drain?

What makes the best shampoo and conditioner for one person doesn't necessarily apply to another, as so much of it comes down to hair type, texture, length, and styling needs.
