2B Hair: What It Is and How to Care for Wavy Hair
If your hair falls more or less straight at the crown, then loosens into soft, S-shaped waves with real body — and dissolves into a halo of frizz the moment the humidity climbs — you almost certainly have 2B hair. It's the middle child of the wavy family: more shape than 2A's barely-there bend, less spiral than 2C's near-curls. Defined waves, natural volume, a weakness for frizz, and the odd flat patch at the roots. Cared for with a light hand, it's some of the most effortless-looking hair there is. The trick is knowing what it actually wants, which is rather less than most of us give it.
Where the numbers come from
The whole 1-to-4 hair-typing language — straight, wavy, curly, coily — was devised in the 1990s by Andre Walker, Oprah Winfrey's longtime hairstylist, as a way to talk about texture plainly. Type 2 is the wavy family, and it splits three ways. 2A is a loose, almost-straight wave with a gentle bend. 2C sits at the far end — thick, coarse, well-defined waves edging into proper curl. And 2B is the comfortable middle: defined S-waves of medium texture, with bounce and volume the others can envy, and a tendency to frizz in damp air that the others mostly escape.
How to care for 2B waves
Wavy hair thrives on restraint. Wash every two or three days rather than daily, with a sulfate-free shampoo — strip the oils too often and your waves lose the very moisture that holds their shape. Condition the lengths, not the scalp, and reach for a weekly mask if your ends feel parched. Detangle only when hair is wet and slick with conditioner, working from the tips upward with a wide-tooth comb or your fingers, never raking from the roots down.
To bring the waves out, scrunch a lightweight curl cream, mousse or sea-salt spray into damp (not soaking) hair, then leave it be. Air-dry where you can; if you're in a hurry, a diffuser keeps the definition that a bare nozzle blasts away. A few things to sidestep: heavy gels and oils that drag waves flat, and too much heat styling, which loosens your natural pattern over time (when you must, use a heat protectant first). On humid days, a leave-in or anti-frizz serum is your friend, and a trim every six to eight weeks keeps split ends from travelling up the strand. If you'd like a framework, the Curly Girl Method — from Lorraine Massey's handbook — adapts beautifully to waves.
Protect them while you sleep
A night of tossing against a cotton pillow is how good waves turn to morning frizz — the rough weave snags and roughs up the cuticle while you turn. Sleep on a silk pillowcase, or tuck your hair into a silk scarf, and the smooth surface lets your waves slide instead of catching, so you wake with the shape you went to bed with and less breakage and frizz. It's the same low-friction logic behind why silk pillowcases are good for your hair — and it costs you nothing but the swap.
Our LS Silk NZ silk pillowcases and silk scrunchies are 22-momme, 100% mulberry silk and OEKO-TEX certified — a gentle place for waves to spend the night.
2B hair asks for surprisingly little: gentle washing, light products, a careful hand, and somewhere soft to rest. Give it that, and those S-shaped waves will do the rest.
