A dry shampoo for day old hair is like an invisibility cloak for Harry Potter- we all need to conceal from time to time. If I could wash my hair as less as possible, I’d do it…think about all the time I could save between washes and blow dries! The birth of dry shampoo years ago helped me prolong my hair washes and I had to stop myself from “sampling” any more of these COLAB Dry Shampoos so I can carry these around in my purse and I will probably soon be purchasing a full sized bottle (after I finish forcing myself to finish the rest of my current stash that I don’t enjoy as much.)
