The hack: Using baking soda and water in place of shampoo gives your hair a deep clean, clearing away product buildup.

How to do it: Mix a tablespoon of baking soda with three tablespoons of water. If you have long hair, double the recipe. Wet your hair in the shower, then pour this mixture over your head. Massage into your roots for about a minute, then rinse. After that, rinse your hair with vinegar (I used apple cider vinegar) to neutralise it.

Did it work?: Um, yes! I had low hopes for this. I had very dirty hair that was also pretty clogged up with dry shampoo, so I assumed the baking soda would do nothing, and I'd just have to wash it again. It felt weird washing my hair without any lather, but it was a pretty straightforward process. I just made my mixture in a glass which I took into the shower with me. I HATED rinsing it with vinegar though – do yourself a favour and make sure none gets in your eyes. That shit STINGS. But once I'd "washed" and dried my hair, I was very surprised by how clean it was. It lacked the bounce and volume that comes with regular shampoo, but it felt soft and silky AF. The only downside was the smell of the apple cider vinegar. I smelled like when you spill wine on the counter but don't bother to clean it up until the next morning.
