There are some beauty products where the range of quality is vast and, on the whole, you get what you pay for (foundations and fragrance, for example) And then there are those where the spectrum of greatness is narrower and the correlation between price and performance less clearly mapped. Until recently, I put shampoo in the latter category.
I felt this way because even the best shampoo and conditioner only stays on your hair for a minute or two, tops. So how much can it truly do before your money goes gurgling away down the plughole? Plus the truth is that past the root, your hair is not a living thing as, say, skin is. It doesn't regenerate and once damage is done, it can't truly be 'undone' despite what some products claim.
