FAQ
Hair straightening questions, answered
What types of straightening do you offer?
We offer the straight perm (magic perm), volume straightening, rebonding for very curly or frizzy hair, and root straightening for regrowth. Your stylist recommends one after checking your hair.
Will my hair look flat after straightening?
Korean straightening is designed for a natural, soft finish rather than flat, stiff hair. If you want to keep body, volume straightening smooths hair while maintaining natural volume, or add a root volume perm.
How do I maintain straightened hair?
As new hair grows, root straightening treats only the regrowth. Care such as a keratin treatment helps keep shine and softness between visits.
Can men get hair straightening?
Yes. Men often choose straightening or a men’s down perm to control puffy sides for a cleaner silhouette.
How long does it take and how much does it cost?
Straightening is time-intensive, so advance booking is recommended. Time and price depend on hair length, texture and method — ask us on WhatsApp for current details.
