Simply Dry is formulated to work across all hair types and hair colours, which makes it a fit for anyone who wants to stretch the time between washes rather than a product aimed at a specific texture. It suits people who want a quick refresh at the roots on second- or third-day hair, or who want extra volume at the base without reaching for a wet wash.

The case for Simply Dry over a plain talc or rice-powder dry shampoo is the combination of rice and tapioca starch with green tea leaf extract, aimed at absorbing oil and refreshing hair without the flat, powdery look that heavier dry shampoos can leave. Because it's positioned for all hair types and colours rather than a specific texture or tone, it's a reasonable single product to keep on hand for stretching washes regardless of what else is in a routine.

Shake the can vigorously before use. Hold it roughly 6-8 inches from the hair, lift sections at the root, and spray directly onto the roots where oil builds up.

Massage the product in with your fingers and comb or brush through to distribute it evenly and remove any visible residue, then style as usual.

What it does well: the starch base genuinely absorbs oil rather than just masking it with fragrance, it's formulated to work across hair colours without a heavy powdery cast, and the aerosol delivery makes it fast to apply at the roots.

What to watch for: like any aerosol dry shampoo, it needs a thorough shake before each use and can leave visible residue if oversprayed or not massaged in fully, it shouldn't be used near heat or open flame because of the propellants, and it is not a substitute for washing — buildup will still accumulate over repeated use without a wash.
