I visited my mom where tap water is as hard as a rock- after a few washes my hair got dry, dull and frizzy (I was breaking out on my face pretty badly too, eh). I wanted a product I could use on wet hair, before blow drying, and that would soften them. This product, combined with rinsing my hair with bottled water at the end of washing, restored their previous (already pretty good) condition.
I don't use it on dry hair because of their structure- straight, fine, flat, they don't tolerate large amounts of product. But as a leave-in conditioner, it this oil works wonderfully. Makes brushing wet hair a lot easier. Smells lovely, a pump or two is more than enough for one use. One bottle will last me for very long. I don't use it too often because I don't want to add too much weight to my hair, especially now when I'm back home (where water is a lot softer) and I don't necessarily need high maintenance conditioner.
Btw: I live in EU, but ingredients list of my product is same as product's on this page, so I decided to write a review here. :)
