People with frizz-prone, coarse, dry, or humidity-reactive hair — including color-treated hair — who want a rinse-out treatment step to use after shampooing, at home, with no professional application required. Not intended for those looking for a leave-in, no-rinse styling cream, since this is a wash-out mask, not a styling product you apply and leave in. Those with fine or low-density hair should use a light hand, since a rich mask like this can feel heavy if overapplied, especially near the roots.

What sets this apart from an everyday conditioner is that it's formulated specifically as the intensive treatment step of a dedicated anti-frizz system, using jojoba oil and oleic acid to target humidity-driven frizz with a claimed multi-day hold rather than a wash-out-by-tomorrow effect, which makes it worth reaching for on top of (not instead of) a regular conditioner when frizz is a persistent problem.

• After shampooing, apply the mask from mid-lengths to ends, avoiding heavy application at the scalp/roots if hair is fine
• Leave on for 3–5 minutes, then rinse thoroughly
• Follow with a heat protectant or topcoat product before blow-drying or flat-ironing for best results

Pros:

• Richer, longer-lasting smoothing effect than a standard rinse-out conditioner (Matrix states up to 96 hours of frizz control)
• Contains jojoba oil and oleic acid to help smooth the cuticle and reduce humidity-related frizz
• Short 3–5 minute contact time fits into a normal shower routine
• Vegan formula

Cons:

• It's a rinse-out treatment, not a leave-in styling cream, so it needs to be paired with a shampoo (and ideally a heat protectant/topcoat) for the full smoothing system to work as designed
• Rich, mask-like consistency can feel heavy on fine or low-density hair if applied too close to the roots
• Contains synthetic fragrance and dyes, which may not suit those sensitive to added colorants or scent
