Hi all! Been tinkering with the idea of trying the Geologie shampoo. I'm a male in his mid-30s and doing anything preventive for hair loss is a high priority, that said, I have been using 'hims' shampoo and conditioner with good results. Now, I use Geologie for just about everything else, so are there any shampoo users out there? How has the shampoo been for you? Have you seen improvement or is it just keeping your hair clean?
