The Korean C-curl is a soft inward bend at the ends of the hair, shaped like the letter C. It gives a feathery, bob-like finish that tapers towards the chin. The style can be done with a salon perm or with a curling iron at home. Three steps get you the home version: lift the roots, curl inwards, then tease and set.
The three steps
Step 1: Lift the roots
Start with volume at the crown, because the C-curl needs bounce to look buoyant rather than flat. Work a degreasing, root-lifting product into the roots, then blow-dry with a round brush.
At the time of the original guide, one pick was Original & Mineral’s Rootalicious Root Lift Spray, priced at US$40 at Sephora. Any lightweight root-lift spray or dry shampoo with some grip does the same job.
Step 2: Curl inwards
Take sections of hair at ear height and wind them around the barrel so the ends turn in towards your chin. Hold for a few seconds so the curl sets, then release. Run your fingers through the curls to separate them into soft swirls rather than tight ringlets.
The original guide recommended Philips’ Easy Natural Curler BHH777, which has an automatic clip-and-curl mechanism and was priced at S$69 in department stores at the time. A standard curling iron works too. Larger barrels give looser bends and smaller ones give tighter curls. Always use a heat protectant before styling.
Step 3: Tease and set
Use a medium-sized boar-bristle brush to tease random chunks at the crown for extra height. Finish with a generous mist of setting spray so the curve holds through the day.
Who it suits, and how to ask for it
The C-curl works best on bobs, lobs and shoulder-length cuts. The inward curve frames the jaw, and it adds direction to ends that tend to fall straight and flat.
The original guide matched the cut to the face shape. For round or oval faces it suggested side-swept bangs with length on top to elongate the profile. For square jaws it suggested plenty of layers around the ears to soften the lines. It cited SNSD’s Yoona as a K-pop example of the look, and presented the style as an easy contrast to the frizzy perms of earlier years.
Salon perm or styling at home
A salon C-curl perm is a Korean-style digital perm that shapes only the lower few inches of hair, wrapped around large rods, and leaves the upper lengths smooth and straight. The result is a single, deliberate inward curve. It lasts roughly four to eight months and replaces the daily step of blow-drying the ends inward.
The salon route involves chemical treatment, so Team Salon in Singapore advises agreeing the haircut and the perm together. It also suggests asking the stylist how the length, layers, fringe and parting will support the shape as the hair grows. It recommends asking for a demonstration of how to guide the ends into the curl while drying at home.
The home method suits anyone who wants to try the look without committing. It needs a curling iron, a root-lift product and a setting spray, plus about as much time as a normal blow-dry.
Variations on the C-curl
- C-curl bob or lob: the classic version. Curl the ends inwards, part in the centre or at the side, and tuck one side behind the ear for a sleeker line.
- C-S curl: a wave through the lengths that settles into a C-shaped curve at the ends. It has more movement than a plain C-curl but a softer finish than a uniform wave.
- Layered cuts: a C-curl on shoulder-length layers with wispy bangs or side bangs. It is the more voluminous take on the look.
For other K-beauty hair ideas, the cropped Korean bob and the “rich girl” look are natural next steps. Both lean on the same smooth lengths and soft, polished ends.
