How much is too much to spend on Shampoo?

A survey conducted by Tresseme discovered that women spend an average of $8 on Shampoo (appx $120 a year for both shampoo & conditioner)

So whether you're a drug store brand user, or a salon quality user....women seem to have an internal limit to what they will spend on Shampoo.....

So what's yours??

I would say that mine is $20 each for shampoo & conditioner (because for a long time I used Fekkai, which was $22 each) and that is probably why I can't bring myself to buy Keratese

At about $35 a bottle...even though women all over SWEAR by it and say its the very best!  I just can't do it!
