OK so I just thought I'd come on here and share so easy money saving wisdom with you all in a hope some of you might share yours too 
OK so for those who want to try olaplex hair treatments, you can buy something called Colorphlex on amazon and ite exactly the same. A trial size (one use) costs less than £7 and you can do it at home. You get stage 1&2. It's amazing stuff. Stir into hair dye, bleach or even a deep conditioner and you won't recognise your hair after I promise.
I wrote to (emailed) Elemis a while ago enthusing about a product i tried and loved. In response they sent me a gift box full of goodies. So if you love a product tell the company's. Not only is it great feedback but some even give you gifts in return.
For Benefit dupes buy from the brand W7. Good products and similar ranges (especially the cheek and lip tints!)
