I've used OGX's shampoos a while ago and ended up picking up this particular variant from Defence Store. It is excellent! Super summer-hair friendly, doesn't dry out your hair and is reasonably affordable for the quality of the product.
I have fine but voluminous hair- and this worked wonders. Pair it with a coloured-hair friendly conditioner (I'm currently using L'Oréal's that comes in a pink bottle- called Serie Expert, A-OX Vitamino Color) and you'll be good to go! I also love the fragrance of this shampoo. If your hair needs a good hydrating shampoo, I'd recommend this.
