Quick answer
What is the difference between a C-curl perm and an S-curl perm?
A C-curl perm creates inward, curved curls at the ends — like the letter C — for a clean, polished look that suits bobs and medium hair. An S-curl perm creates soft, flowing waves like the letter S for more volume, ideal for longer or layered hair. At Soonsiki Moment Hongdae, both are customized to your face shape and haircut.
- C-curl Inward ends, clean & polished
- S-curl Flowing waves, more volume
- C-curl suits Bob or medium-length hair

FAQ
C-curl & S-curl perm questions, answered
Which one should I choose, C-curl or S-curl?
Choose a C-curl for a clean, polished, minimal look — it works well with bobs and medium-length hair. Choose an S-curl for softer, more dynamic waves on longer or layered hair. Your stylist will recommend one after your consultation.
Can a C-curl or S-curl be done as a digital perm?
Yes. Both are popular as a digital (heat) perm, which gives defined waves when dry. We choose the technique after checking your hair condition.
Does an S-curl work better with a layered cut?
S-curls are ideal for longer hair or layered cuts, because layers help the waves move naturally. Many guests combine both in one visit.
How long does it take and how much does it cost?
Time and price depend on your hair length and condition; advance booking is recommended because of the service duration. Ask us on WhatsApp for the current price and time.
I want bigger waves — what are my options?
