"I love this shampoo. It is the best I've ever used, but with the last order of 3 bottles, I found it to be quite different from previous purchases and orders. It has always been a thinnish, white, milky looking formula. These 3 bottles contain a dark gold, thick formula as if it is very old. There is a code stamped on the bottle but it is not discernable as a date. As far as I can tell, the shampoo still gives the curvy waves I seek with just a little less wave than I have experienced previously. Working with Pharmapacks is excellent. Very reliable company and keeps its predicted ship dates. In fact my last delivery arrived a day before promised."
