This is a great product that I’ve used for some time now. It helps give slight lift and control to my hair in a natural way.

Thank you for your review Charlotte. Glad to hear you have been enjoying using Definer.

Best on the market

Have been through lots of different products trying to match up to Andrew Collinge Design and Shine (discontinued), finally have a product that is as near as I’m going to get to it. Not quite design and shine though but still the best on the current market. Only need a small amount, it does define so you can neaten and manipulate (well define) your hair and does put a nice shine on it too. But please bring back D & S


Bought this as had used Design and Shine and have been searching ever since to find something to equal it! Definer felt heavy and sticky on my hair, although it did give a nice shine. Please, please bring back Design and Shine! There is nothing on the market that comes anywhere near!

I last purchased this product almost 12 months ago and at the time left a review saying I was disappointed with the amount of packaging used. Upon receiving this product recently I was pleasantly surprised to find that the packaging has been greatly reduced. I was really impressed that my previous comments have been taken on board. Thank you.
