BUt bluegrrl, I'm hardly wealthy. I always bought Kiss My Face or one of the above brands when they were on sale, when my social assistance cheque came in, & used it sparingly (all you need is a little good shampoo/conditioner, in truth).
In fact recently I bought a discounted bottle of KMF Sahaira shampoo for 4 bucks.
When I look at Salon Selectives & all that toxic stuff, it costs more than that.
The other brands I mentioned seem to range between $8-$12 Canadian where I buy them, & a bottle lasts me at least a couple of months.
My hair is healthier for it, & no worries about animal torture & ecological impact.
