How to build the perfect routine for wavy hair (2A, 2B, 2C)

Wavy hair is perhaps the trickiest to tame. Too light to handle rich products, too textured to make do with conventional ones, it constantly swings between defined waves and flat lengths. The good news? With a wavy hair routine designed for its unique structure, your waves can finally reveal their full potential: light, defined, alive, frizz-free.

In this guide, we walk you through every step to build your personalised ritual, with the right products, the right gestures and the right frequencies.

Understanding wavy hair before building your routine

Wavy hair corresponds to type 2 in the classification (2A, 2B, 2C). It forms a loose S shape rather than a spiral, which makes it particularly prone to two issues:

• Weighing down: because the strand is fine and the wave loose, a product that's too rich flattens the wave and makes the movement disappear.
• Frizz: the cuticle opens easily with ambient humidity, creating that characteristic fuzzy halo.

Unlike curly or loose coily hair, wavy hair doesn't suffer from marked structural dryness. Its main challenge isn't heavy nourishment but balance: moisturising enough without weighing it down. If you're still unsure about your texture, our article on the difference between wavy and curly hair will help you see things more clearly.

The wavy hair routine in 4 steps

Every routine suited to textured hair rests on 4 key steps: cleanse, detangle, moisturise, define. For wavy hair, each step must favour lightness.

Step 1 — Cleanse gently

Shampoo is the starting point. Go for Perfect Match, our shampoo designed for fine hair: it cleanses without drying, brings volume and shine, while preserving the lightness of the wave.

The right gesture: massage the scalp with your fingertips (never your nails) to stimulate blood circulation and dislodge impurities. Let the lather glide naturally down the lengths as you rinse.

Frequency: 1 to 2 times a week depending on your activity.

💡 Once a month, you can add a clarifying ritual with Tropical Détox to remove built-up residue and bring bounce back to your waves.

Step 2 — Detangle and nourish with a light conditioner

An essential step, often overlooked. Apply Cream Conditioner to the lengths and ends, avoiding the roots. Its formula was specifically designed to detangle wavy hair without weighing it down, while adding volume and shine.

The right gesture: detangle from ends to roots with your fingers or a suitable brush. Leave on for 2 to 3 minutes, then rinse with lukewarm water (or cool to tighten the cuticle).

Step 3 — Moisturise with a suitable leave-in

This is the step that changes everything. On very wet hair (squeezed in a Kiss Towel microfibre towel), apply Kurl Potion, our ultra-light leave-in, perfect for fine, wavy hair.

Why Kurl Potion? Its fluid texture moisturises the strand deeply without weighing it down, which preserves the wave's mobility. To understand why this step is crucial, read our article What is a leave-in?.

The right gesture: distribute with your palms, then smooth from roots to ends to avoid knots.

Step 4 — Define with a light styler

Still on soaking-wet hair, apply Boost Curl, our defining styling jelly. For wavy hair, a well-distributed dab of product is better than an excess that would stiffen the wave.

The right gesture? Scrunching: press your lengths accordion-style towards the scalp, palms facing up. This gesture amplifies the natural movement of your waves.

Drying wavy hair: plopping or diffuser?

Drying is the step that makes or breaks definition.

Plopping

Lean your head forward and wrap your lengths in a cotton t-shirt or a microfibre towel. Leave for 15 to 30 minutes: the wave forms naturally and frizz is limited.

Diffuser drying

For more defined waves, use a hairdryer with a diffuser, head down, on lukewarm heat. Avoid handling your waves while drying: every movement creates frizz.

You can also let it air-dry, ideal for preserving natural softness.

Extra care to enhance your waves

A routine isn't complete without targeted weekly care.

• Pink Power Mask: this protein mask strengthens the strand and reduces breakage when brushing. Use once every 15 days, on lengths and ends, for 5 to 10 minutes. Ideal if your waves lack tone or if you style your hair regularly.
• Repair Time: for lengths that tend towards dryness, once a week, 15 to 30 minutes, ideally under a heat source.

Protecting wavy hair at night

Friction against the pillow is enemy number one for waves. In the morning: frizz, flattened waves, breakage. The solution? The Silky Twist silk night bonnet, or the Kiss Pillow pillowcase. All our tips for protecting your hair at night are detailed in this full article.

FAQ — Wavy hair routine

How often should you wash wavy hair?

1 to 2 times a week is enough. Washing too often strips the protective sebum and encourages frizz. Between two shampoos, a refresh with water and leave-in is enough to revive the wave.

Why does my wavy hair go flat after a few hours?

Too much product, products that are too rich or dry brushing flatten the wave. Favour light formulas like Kurl Potion and avoid touching your hair once it's dry.

Can I use the same products as a friend with curly hair?

Not ideal. Curly hair (3A/3B) needs more nourishing care (Pink Paradise, Kurl Nectar) that weighs waves down. Each texture deserves its own routine.

How can I limit frizz on wavy hair?

Three levers: never touch your hair while drying, use a suitable leave-in on very wet hair, and sleep on a silk pillowcase.

Should I do a protein mask every week?

No, once every 15 days is enough with Pink Power Mask. Too much protein can make the strand stiff.
