I first came across Calia through Holistichabits/Sarah Nagel on YouTube. It's been on my wishlist for a while until I finally got around to making a purchase. I may no longer be on the whole 'natural' kick but I still enjoy using haircare that is derived from natural ingredients.
I've had this regimen for about two months. I think they are very similar to the Al'chemy shampoos I used before. Calia uses unrefined ingredients and Al'chemy uses coconut-derived chemicals but I don't notice much difference. If Calia finds a way to ship items cheaper internationally (other than US and Canada), I might pick their products up again. For now, Australia offers many natural brands and Al'chemy is pretty close. Nevertheless, I recommend Calia to anyone who lives in North America and can take advantage of free shipping when you reach CAD$69.
For anyone wanting to try Calia, I recommend the hydrating line. It smells divine with the geranium oil and is gentle on the hair.
I find the purifying shampoo too drying for my hair but it is effective as a deep cleansing shampoo. Even my sister, who is often complaining that no shampoo out there is good enough for her oily roots, did not like how drying this shampoo was.
