My perennial issue is battling with my flat hair. There are very few things I can say about haircare because the truth is that I don't really do much with my hair. I buy drugstore shampoo and conditioner, I don't heat style my hair because I am terrible at it and also because my hair cannot hold a curl for the life of it, and I have never color-treated my hair. Honestly I spend the majority of my life with my hair in a super chic (ha) ponytail or in a super messy bun.
Lately though I've been trying to up my game to varying degrees of success. The most success I have found has been with the above combo - Batiste Dry Shampoo and Bumble & Bumble Thickening Dryspun Finish Hairspray. The Batiste dry shampoo is one of the best I've ever tried. It doesn't leave a white cast, absorbs grease without making my hair feel overly powdery and gross, and just basically does what it says on the can. The Bumble & Bumble hairspray adds just the right amount of pizzazz to my hair without being sticky or heavy-feeling. My hair still feels like hair when I apply it, just a little more voluminous.
Although I don't get crazy-dramatic results with these products, on my hair any small increase is a huge deal because it's so resistant to product and styling. These are definitely in heavy rotation around these parts!
