This is BY FAR the best dry shampoo I’ve ever tried. I have dark straight hair that gets oily very quickly, and I also have a sensitive scalp so I’ve struggled to find a dry shampoo that doesn’t itch and that doesn’t just make my hair look matte and chalky. It took some trial and error to make this work but I ended up tapping some product into the lid and used a makeup brush to apply and WOW my hair looks so clean and fluffy that I forgot I hadn’t washed my hair the next day. Zero irritation and a TINY amount of product goes a very long way. Doesn’t make my hair look white either because I use so little product and it’s such a fine dust that rubbing it in a bit makes it blend with my dark hair. Could not recommended enough!
