Between long-haul flights, fitness classes, and work-to-cocktails primping in the office bathroom, the modern girl has many occasions to use dry shampoo, and for all of these situations Cake Rush Brush Dry Shampoo Powder Brush ($22) promises to be a godsend. Each portable capped brush comes loaded with dry shampoo powder meant to match different-coloured locks. True to the product's name, you can simply brush and rush.
The Rush Brush scores major points for convenience, but figuring out the brush mechanism was a bit of a learning curve. The middle part twists from on to off to control the powder dispensing, but in the off position the centre part expands and slides up over the brush so you can replace the cap without crushing bristles. Once you've placed the cap on, twist the centre part so the arrows are exactly halfway between on and off, and the brush will stay collapsed.
Once I figured it out though, the Rush Brush was pretty handy. The mostly natural, paraben-free powder quickly and effectively de-greased bangs and roots after barre classes. The brush dispensing mechanism allowed me to control exactly how much product I needed so there was never any chalkiness or residue caused by applying too much. And although I received the shade intended for light locks, it never showed against my dark hair as long as I brushed it on judiciously. The only downside to the Rush Brush seems to be the quality of the brush itself (it keeps shedding bristles with every use), but never mind that: I'll definitely be keeping this one around in my work and gym tote.
