Trichological Classification: Decoding 2A, 2B, and 2C Wave Geometry

To build an effective routine, one must diagnose where hair sits along the Andre Walker Hair Typing System. Type 2 hair is defined by loose S-shaped curvature. Type 2A hair is fine, straight at the roots, and cascades into gentle loose waves toward the ends. Type 2B features more prominent, defined S-waves starting midway down the head, with higher frizz susceptibility.

Type 2C hair features deep, resilient S-bends starting directly at the root, borderline coiling into loose ringlets. Unlike Type 3 curls (which have a circular spiral geometry) or Type 4 coils, wavy hair follicles produce hair shafts with semi-oval cross-sections. This shape allows natural scalp sebum to travel downward much faster than in tight curls, making wavy hair uniquely susceptible to going limp and greasy if overloaded with heavy shea or coconut butters.

The 5-Step Protocol: Engineering Wave Clumps

The secret to defined waves lies in creating uniform 'wave clumps' while hair is saturated with water. Step 1 (Low-Poo): Cleanse the scalp with a sulfate-free foaming shampoo to clear sebum without stripping. Step 2 (Weightless Condition): Apply a silicone-free conditioner strictly from the ears down, finger-detangling all knots. Step 3 (Squish to Condish): Cup warm water in your palms and repeatedly scrunch upward toward the scalp; the squishing sound pushes water and conditioner deep inside the cortex, causing strands to naturally gather into thick, hydrated S-ribbons.

Step 4 (Cast-Forming Gel): Glaze a lightweight polymer gel over the soaking wet wave clumps using 'praying hands' technique, scrunching upward. Step 5 (Microplop & Diffuse): Wrap hair in a smooth cotton T-shirt for 10 minutes (microplopping) to absorb dripping water without roughing cuticles, and diffuse on low heat until 100% dry.

The Art of 'Scrunching Out the Crunch' (SOTC)

The greatest fear among wavy-haired individuals is having hair look wet, stiff, and crunchy like an early 2000s boyband. This crunch is the 'gel cast'—a hard, protective shell formed by dried polymers that holds the wave pattern intact while moisture evaporates.

Do not panic when your hair dries stiff. Once (and ONLY once) the hair is 100% bone-dry, dispense 2 drops of weightless moringa or squalane oil onto your palms. Gently cup and scrunch upward throughout your hair. The mechanical friction breaks the rigid polymer shell, instantly releasing ultra-soft, bouncy, touchable, and voluminous waves that hold their shape for days.

Key Solutions to Everyday Concerns

Why does my wavy hair go completely straight when I brush it dry?

Wavy hair is held in its wave pattern by weak hydrogen bonds. Dry brushing physically tears apart wave clumps, separating adjacent strands and creating an electrostatic cloud of frizzy, semi-straight hair. Only brush or comb wavy hair while it is wet with conditioner in the shower.

Can I use the 'Curly Girl Method' for my Type 2 wavy hair?

Strict Curly Girl Method (which bans all shampoos in favor of co-washing with heavy conditioner) usually fails on wavy hair. Wavy hair needs regular low-poo cleansing to remove sebum and lightweight styling products to avoid being weighed down into limp strings.

How can I refresh my waves on Day 2 and Day 3 without re-washing?

Mist hair lightly with a spray bottle filled with water and a pump of leave-in conditioner until damp. Scrunch gently to reactivate the residual styling gel from Day 1, and let air-dry for 15 minutes to restore bouncy definition.
