If you have hair, you need this product.

If you have hair, you should own dry shampoo. That’s my opinion, anyway, and mum told me it counts.

It’s a fantastic, very-fine white talc-esque powder you spray onto your roots to soak up oil, and is bloody terrific. I panic when I run out. (Have been known to use actual talc, and even white flour.) Need it. Always. Only wash hair twice a week and rely on it heavily to not offend friends and strangers alike on that last day before washing. (See below for visual evidence.)

Why should you try it if you haven’t already converted?

It’ll give you another day of clean hair. It will prolong a blow dry. It will give you volume and lift. It will create a terrific, pillowy base for pulling your hair up. It will save your ass when your hair is filthy. It will expertly cook you osso bucco.

It works on all hair colours, although there are special brunette and redhead ones (by Batiste and Bumble & bumble) that might delight those of that hair colour more than the regular white powder type. Get the most of it by using a lot, massaging it in, then brushing and/or blow drying it through. DO NOT BE SCARED BY THE GREY LOOK. It will subside quickly. However, this is why you can’t use it for any more than 2 days: too much powder build up; too dandruffy looking.

Now, here’s a very basic How To, with a bonus little fuzzy top-knot at the end…

Do you use dry shampoo? Do you have a preferred brand?
