This range is really good and best of all super affordable.
You only need the tiniest amount, so it really lasts a good few months. I get atleast 3 - 4 months use out of it. It does not weigh your hair down, but your hair feels super moisturised.
My only dislike - the smell - it reminds me of mosquito repellent o_O Other than that I would say you need this in your life...
