Prevent frizz by sealing the cuticle and locking in moisture. Wash with a sulphate-free anti-frizz hair shampoo two to three times a week, follow with a matching conditioner from mid-length to ends, and rinse with cool water to lay the cuticle flat. Dry with a microfibre towel rather than a terry-cloth towel, and always use a heat protectant before blow-drying or styling. On non-wash days, refresh with a light oil or leave-in cream instead of brushing dry hair, which can rough up the cuticle and trigger fresh frizz.

A matched duo will always outperform two unrelated bottles, because the conditioner is formulated to seal what the shampoo opens up. The Limitless Anti-Frizz Duo Pack is the easiest sulphate-free pick. For thicker hair or hair that's been through a smoothing service, the Brasil Cacau anti-frizz pair is the salon-grade option. Match to your hair type, not just to the word "frizz" on the label.

Two to three times a week works for most hair types. Daily washing strips out the smoothing build-up and triggers more frizz, not less. On non-wash days, refresh with a leave-in cream or a light oil at the ends. And don't run a brush through dry frizzy hair, ever. Re-wet, re-section, then style.

Anti-frizz shampoo targets the cuticle (sealing, hydrating, anti-humidity). Smoothing shampoo targets the hair's texture, reducing waves and bulk so hair sits visibly straighter on the brush. There's overlap, but if your main issue is humidity and dryness, anti-frizz is the right place to start. If what you actually want is a noticeably straighter finish, look at the smoothing range instead.

Yes, as long as you pick a sulphate-free formula. Sulphates strip natural oils and artificial colour in the same wash, so a sulphate-based anti-frizz shampoo will fade your colour faster than it smooths the cuticle. Limitless F1 Anti-Frizz Shampoo and Natural Look Static-Free Anti-Frizz Shampoo are both sulphate-free and colour-safe.

They do, but curly hair needs the heavier formulas with humectants and proper slip. Lightweight anti-frizz washes designed for fine hair won't provide nearly enough moisture for curls. The Devacurl No-Poo range is built around exactly this, pairing with a co-wash routine instead of daily lathering.
