The Macadamia Healing Oil is doing the rounds on blogs and YouTube at the moment. I do like it, but personally I think the Deep Repair Masque is the one to buy from that range.
Whenever I go to the hairdressers my sister uses this on my hair. It smells amazing and leaves me hair so silky and soft. The scent lingers for a few days, which I love. There's nothing worse than a product that smells gorgeous but doesn't actually transfer or last!
Macadamia products are fairly expensive. Luckily I can get them cheaper because of my sister's trade card, but they're still quite pricey. If you can get your hands on one of these sachets in a local hairdressers it's definitely worth trying out; I can get two washes of my hair from this. Once I've used it up I'll be asking my sister to get me a big pot!
