What I learned in point form:
- Washing once a week (or every other shampoo), should be enough. But that depends on your hair's texture and brassiness.
- You need only a purple shampoo or a conditioner, not both. Once again I'm sure there are exceptions to this rule, but my hair isn't one.
- The shampoo must be a deep rich purple, not lavender, not light purple, and not transparent.
- Purple shampoo isn't a great cleanser, you might need to shampoo twice, if you're also going for cleanliness. My hair is fine, I don't need to.
I wash my hair daily, but I only use this shampoo once a week. The colour is gorgeous, suddenly dark purple is becoming my favourite colour. The scent is not my favourite. I has a bit of a chemical "treatment" scent, not something I want to linger with. It's not oppressively strong, I'm just not a fan.
Rinsing this out is my favourite part, not only because the scent is gone, but for the gorgeous lavender suds that spin down the drain.
