“Lasts forever, leaves my hair lovely and clean - I can't believe they cost a fraction of what others are charging for a single bar! I have terrible problems with allergies and this is so far the only shampoo bar I have been able to use for any length of time - been using them a year or so now and still going strong. I am so grateful for these. I just ordered another batch of 5 and suspect they will last me well over a year!”
