Quick answer
What is a digital (heat) perm?
A digital perm is a heat-based perm that uses temperature-controlled rods to set soft, defined curls. Unlike a traditional cold perm, the waves show most when hair is dry, giving a natural Korean look with little daily styling. At Soonsiki Moment Hongdae, curl size and placement are customized after a hair analysis.

FAQ
Digital perm questions, answered
What is the difference between a digital perm and a cold perm?
A digital perm uses heat to set waves that look defined and glossy when dry, while a cold perm uses a chemical setting and tends to show more texture when wet. See our Korean hair perm overview to compare all types.
Which digital perm styles are popular?
Trending options include the C-curl and S-curl digital perm, glam wave, layered wave, natural body wave and face-framing digital perm. Read more on our C-curl / S-curl perm page.
Is a digital perm suitable for short hair?
Digital perms are ideal for medium to long hair. For shorter styles or roots-only lift, a root volume perm may suit you better; we will advise after checking your hair.
How long does a digital perm take and cost?
It is a longer service, so advance booking is recommended. Time and price depend on your hair length and condition — ask us on WhatsApp for current details.
How do I care for my digital perm?
Your stylist gives aftercare guidance at the end of the service. Gentle products and care treatments such as keratin help keep waves soft and shiny.
