Writing this solely as a word of warning to anyone with very fine hair who might be thinking of buying this shampoo: don't do it!
I'd been using this shampoo once a week for about a year. Loved it. Amazing scent, nice lather, and it left my hair feeling extra clean. Over the last few months, I stopped alternating shampoos and started using this almost exclusively. This was a mistake. My hair began falling out in clumps everytime I washed it. I wracked my brain trying to figure out what was causing it. Stress? My thyroid? Recent weight loss?? This went on for 2 months.
One day, I happened to use a different shampoo. Lo and behold, I lost just a few hairs. Next shampoo: same thing. I realized it HAD to be the Malin+Goetz shampoo I'd been using.
It's now been 2 weeks since I last used it, and my hair has stopped falling out. I'm sure this is a great shampoo for a lot of people, but it is clearly wayyyy too harsh for fine hair.
