I'm a big user of dry shampoo, since I have oily-yet-dry hair. If I can go a day without washing it, I will, to prevent the lengths from drying it out any more than necessary. But the roots get greasy quickly, so dry shampoo is absolutely necessary if I want to go more than 24 hours between washes. In fact, even if I wash my hair before bed, I usually need a little dry shampoo to get me through the next day without my hair going limp and stringy. In a pinch, corn starch works just fine. But sprays are usually easier and quicker to use, so I've tried (and reviewed) a lot of them in an attempt to identify my favorite one.
And I think I have found the best one! Only it's not the product I'm reviewing here. It's Batiste Dry Shampoo in Cherry, which costs about $8. The many other fragrances of Batiste presumably work just as well, but this is my favorite scent. I went through two cans last fall and winter and didn't have time to write up a proper review (just a quick one on Instagram). When I replace it, I will review it, finally.
In the meantime, I've been using Klorane Gentle Dry Shampoo with Oat Milk. Like many of the other pricier products I've reviewed here during the last year, I wouldn't have tried this if I hadn't been able to use Birchbox points to buy it. Even so, I got it in a Birchbox sale, so I didn't have to spend a full $20 worth of points on it. Klorane always pops up when people talk about their favorite dry shampoos, so I wanted to see if it was somehow better than the cheaper ones I've used. I've fallen into that trap before. It's not. But it does have some good qualities.
One of the most interesting things about this dry shampoo is the packaging. It's not an aerosol can. It's a flexible plastic bottle that you squeeze to send a poof of powder out of the nozzle. It works pretty well, although of course you can't get a continuous spray like you can with an aerosol, so you tend to end up with powder concentrated in certain spots. But non-aerosol dry shampoos seem to last a lot longer than aerosols. I just finished the Oscar Blandi powder reviewed here last week, and I've been alternating this Klorane with that since at least last December, and I think it's still about half full. (It also comes in a regular aerosol can.)
