As soon as humidity rises, frizz follows: the hair fibre absorbs moisture from the air and swells. In summer that can undo a careful styling job within the hour.

The answer is a routine that locks moisture into the hair while keeping outside moisture out. These five steps help you keep your hair smooth and under control, even on the most humid days.

01 Start with a smoothing shampoo

Frizz control starts in the shower. Choose a mild smoothing shampoo with keratin, such as one built on the Keratin Healing System from L'ANZA. It cleanses gently, calms the hair fibre and helps hair retain its own moisture instead of pulling it in from the air. This creates a smooth base for the rest of your routine to build on, and makes hair easier to handle from the first wash.

02 Condition to seal the cuticle

Never skip conditioner if frizz is your enemy. A smoothing conditioner seals the cuticle, giving airborne moisture far less grip on your hair. Apply it to the lengths and ends, leave it in briefly and rinse with cooler water, which helps close the cuticle even further. The result is more shine, less frizz and hair that stays easier to style throughout the day.

03 Add a lightweight leave-in treatment

A leave-in adds a light protective layer that keeps airborne moisture out without weighing hair down. The Keratin Healing Oil Hair Treatment absorbs quickly, fortifies the hair against frizz and adds a healthy shine. Work a small amount through towel-dried hair before styling. Your hair stays nourished and protected all day, even as the humidity climbs.

04 Style with a protective foam

When styling, pick a product that actively defends your look against humid air. The Healing Style Design Foam offers flexible hold and forms a barrier against humidity, so your style holds up all day. Distribute the foam through damp hair, then blow-dry or style as usual. As a bonus, it adds volume and texture without sacrificing smoothness.

05 Finish with an anti-humidity spray

Round off your routine with a spray that keeps moisture at bay. The Healing Style Thermal Defense Spray not only protects against heat from styling tools, it also lays a final shield against humidity over your finished look. Mist it lightly over your styled hair for an extra layer of protection that locks everything in place. Your hair stays smooth and polished, even on the most oppressive days.
