On tour, there's dry shampoo - I use the one by Bed Head.
I think my best friend is dry shampoo and dry texturizer spray.
My hair is super fine, so I love using Batiste Dry Shampoo to give it volume after I shower and dry my hair. It also gives me extra body and texture for when I choose to wear my hair in a French braid.
Unite has a great dry shampoo called 7Seconds. After a hot yoga class, when I'm super sweaty I spray this on and my hair comes back to life. Miraculous!
I rinse my hair with Coca-Cola sometimes. I don't like my hair when it's washed - it's fine and limp - but Coca-Cola makes it tousled, like I've gone through the Amazon or something.
When I do my own hair, I love Oribe Texture spray and Redken dry shampoo whenever I'm in a rush. It gives it texture and makes it look clean!
I always use dry shampoo, even if my hair isn't oily. It gives me so much texture and that bedhead vibe.
Dry shampoo is just really awesome because it'll keep your hair light, but it'll give it texture so that you can move it and style it, but it'll kind of just stay in place - so I really love dry shampoo on shorter hair.
