Greasy Roots & Oily Hair: The Best Shampoo in NZ (Stylist Guide)

If your roots are flat and greasy by the next morning but your ends still feel dry, you don't have "oily hair" — you have an oily scalp and thirsty lengths. They need different treatment.

The classic mistake is washing daily with a harsh shampoo. That strips the scalp, which panics and produces more oil, so you wash again. Breaking that cycle is the whole game.

Balance the scalp, don't strip it

Kérastase Spécifique Bain Divalent is built exactly for this — it regulates oil at the root while keeping mid-lengths and ends comfortable, so you can stretch the time between washes. For a deeper weekly reset, Spécifique Argile Équilibrante is a balancing clay cleanser that pulls excess oil and build-up without leaving hair squeaky and tight.

Stretch washes with a good dry shampoo

A genuinely good dry shampoo buys you a day without the powdery residue. Sebastian Drynamic+ refreshes roots and adds a little stylable body. Redken Invisible Dry Shampoo is the residue-free choice for darker hair where chalkiness shows. Spray at the roots, wait 30 seconds, then massage in.

The habits that actually help

• Wash less often, not more. Aim to stretch by one extra day at a time.
• Keep conditioner off the scalp — mid-lengths to ends only.
• Rinse in lukewarm water and finish cool; hot water drives oil rebound.
• Stop touching it. Hands move oil from scalp to lengths.

Greasy and itchy or flaky? That's often a scalp imbalance — see our dandruff & itchy scalp guide.
