Mixed Chicks Leave-In Conditioner is built for curly and wavy hair that needs help with tangles, frizz, and curl definition, including hair that's been chemically relaxed in the past and is transitioning back to its natural texture. It's also formulated to work on human-hair and synthetic extensions and weaves, so it suits anyone maintaining those alongside their natural curls.

Curly and wavy hair loses moisture and gains frizz faster than straight hair, and a leave-in that's rinsed out too early doesn't get the chance to do that work. This one is designed to stay in, locking moisture into the curl pattern while cetearyl and cetyl alcohols and hydroxyethylcellulose help hold the style together as it dries, so curls clump and define instead of separating into frizz.

Apply to soaking wet hair and scrunch it through from ends to roots. Wring the hair gently with your fingers to distribute the product evenly and remove excess water. Air dry, or use a diffuser or hooded dryer on low heat if you're short on time; a towel or blow-dry isn't needed. On a second-day refresh, re-wet hair slightly and work through a small amount before restyling.

• Pro: detangles and defines curls in one no-rinse step, which shortens wash-day routines
• Pro: works on natural curls, waves, and human or synthetic hair extensions and weaves
• Pro: leaves in a lightweight silicone (amodimethicone) rather than heavier oils, so it adds slip without a greasy feel
• Con: contains synthetic dyes (Yellow 5, Yellow 6) and several fragrance components (linalool, geraniol, citronellol and others) that can matter to anyone avoiding synthetic colorants or fragrance allergens
• Con: includes a chemical UV-filter ingredient, which is worth knowing if you're specifically avoiding that ingredient class in leave-in products
