Hello there Henry -- good news for you....the product you are looking for [and recommended here by Toplace] is ``Back2natural`` colour restorer/conditioner. It will be faster for you to order it from the UK supplier [I went to order it from the USA supplier, and they advised me of the UK site ] So what you need to do is go to http://www.myhairdirect.com, click on the ``online shop`` link, then click ``Shampoo and conditioner``...down the page you`ll see the Back2natural product.... you need the `Dark natural ash brown`bottle for your 1b system..it`s a good product.... have a look at their ``Enhance`` leave-in conditioner [with sunscreen built in] as it`s for daily use ---it`s in the tall green bottle...it`s really really good... I`m going to post a pic of it here shortly ... otherwise just go onto the site there guys and have a look...best wishes ... Paul.
