The Science of Curls

Type 2 (Wavy)

Type 2 waves are bendable, can be fine to coarse, and have a definitive S pattern that lays closer to the head.

Type 2A

Those with hair type 2A have a fine, barely-there tousled texture that's very easy to straighten. People with this texture have to be wary of using heavy styling products that can easily weigh their strands down, rendering them limp and lifeless. If you've got this hair texture, be sure the products you're looking for are formulated with a lightweight consistency like our Curl Rhythm Shampoo and Conditioner.

Type 2B

2B hair lies flatter at the crown with defined S-shaped waves starting from the midlength. Strands are thicker in diameter than a 2A, and you'll have to put a bit more elbow grease into getting it straight.

Type 2C

2C waves are thick and more susceptible to frizz. The S-bends are well-defined and begin at the roots. In between shampoos, use a non-lathering, sulfate-free co-wash so as to not strip essential moisture from strands, like our Curl Rhythm Hydrating Cleansing Conditioner. This particular product is formulated to work beautifully on all curl textures.

Nourishing Curls

Type 3 (Curly)

Type 3 curly hair can range from loose, buoyant loops to tight, springy corkscrews which have some sheen but are prone to frizz.

Type 3A

3A strands tend to be shiny with large, loose curls that have a diameter about the size of a piece of sidewalk chalk. Scrunch the Curl Rhythm Curl Gel into your dry hair to help emphasize the curl texture. Keep your hands (or brush or comb) from touching your curls afterward, or you run the risk of having a halo full of frizz. To maintain those juicy springs, simply apply the Curl Rhythm Curl Cream on your hair to act as a curl refresher when your hair needs a boost.

Type 3B

3B types have springy ringlets with a circumference similar to that of a Sharpie marker. This texture can get dry, so try our Curl Rhythm Curl Gel on wet hair to attract moisture to strands.

Type 3C

3C curls are tight corkscrews that range in circumference from a straw to a pencil. Strands are densely packed together, giving way to lots of natural volume. Frizziness is common with this type. If that's not a look you're into, use Curl Rhythm's sulfate-free Shampoo & Conditioner for a product that won't dry out your hair even more.

The Science of Curls

Type 4 (Coily)

Coily hair, commonly referred to as Afro-textured or kinky hair, is naturally very dry and spongy in texture — and can be soft and fine or coarse and wiry. Strands form very tight, small curls of zig-zags right from the scalp and are prone to major shrinkage.

Type 4A

People with hair type 4A have dense springy, Spatterned coils that are about the same circumference as a crochet needle. Styling should be done more frequently to keep this coily texture popping with soft, pliable strands. Curl Rhythm’s Curl Cream and Leave-in Conditioner is a must for adding more moisture to daily wash-and-go styling.

Type 4B

4B strands are densely packed and can bend in sharp angles like the letter Z.

Type 4C

4C textures are similar to 4B textures, but the tightly-coiled strands are more fragile and have a very tight zig-zag pattern that is sometimes indiscernible to the eye. This hair type experiences the greatest amount of shrinkage — about 75% more — than the other textures.
