Most clients first hear about JK as an anti frizz hair treatment, but JK is more versatile than that. At Salon Plus, JK is “an Alkaline Hair Reconstruction Treatment, powered by MUCOTA Japan, designed to reconstruct the hair and restore it to a healthier, stronger-looking, smoother and more manageable condition.” It is not one fixed service. It is a system with six options, each giving a different finish, from smooth to bouncy to straight. Led by Creative Director and JK Specialist Audrey Tan, our team chooses between them only after assessing your hair. Here is how to tell which one sounds like you.
1. How JK Works and Why the Consultation Comes First
The Transformation: The right JK service can reduce frizz and puffiness, restore body to weak hair, improve shine and manageability, and create “different finishes according to the client’s needs, from volume and movement to smoothness or straightness.”
Service Breakdown: JK is described as “a customisable hair reconstruction system that allows the stylist to work according to the client’s existing hair condition, texture and desired result.” It can be adapted for “previously permed, straightened, coloured, dry, frizzy, damaged, weak or difficult-to-manage hair.” Because alkaline chemistry swells the hair fibre and opens the cuticle [2], how the system is applied matters as much as the product. That is why every JK service begins with a professional consultation and hair assessment. Results vary from client to client, so the assessment always comes first.
Styling Trick: Before your consultation, note what annoys you most about your hair: frizz, flatness, roughness or bulk. That one word usually points to the right JK service.
Tip for styling in SG weather: With mean annual humidity around 82%, and above 90% before sunrise [1], Singapore hair needs a finish that holds up to moisture. Say how humid days affect your hair specifically.
What to Expect from Maintenance: Treatment time is approximately 2.5–3 hours, depending on hair length, condition and the JK service selected. Results may last approximately 5 to 10 months, depending on hair condition, the service and home care.
| JK service | Original price | Promotion price |
|---|---|---|
| JK Anti-Frizz Treatment | $550 | $250–$350 |
| JK Perm | $750 | $350 |
Promotion prices are for a limited time, and your price tier is confirmed during your hair assessment. See our JK promotion page for details.
2. The Smoothing Family: JK Anti-Frizz, JK Smooth and JK Silk
The Transformation: All three calm and smooth the hair, but they differ in how far they go.
Service Breakdown: Here is how the three compare:
- JK Anti-Frizz: “For frizzy, dry, unruly or difficult-to-manage hair.” It reduces frizz and puffiness while keeping hair “natural-looking rather than appearing excessively flat or stiff.” This is the best starting point for most humidity-frizz clients. See our comparison of rebonding vs keratin vs anti-frizz.
- JK Smooth: “For clients who want smoother and easier-to-manage hair while maintaining natural movement, softness and body.” It suits hair that is manageable but rough or unruly, rather than heavily frizzy.
- JK Silk: “For clients who want an especially soft, silky, smooth and glossy finish with improved touch, shine and fluid movement.” It suits clients whose main goal is shine and touch.
Styling Trick: After any smoothing JK service, blow-dry in the direction of the cuticle (root to tip) with the nozzle pointing down for maximum gloss.
Tip for styling in SG weather: Choose sulfate-free cleansing. Research shows alkaline shampoos increase friction between fibres and can cause frizz [3]. Our guide to at-home frizz control vs a salon anti-frizz treatment covers home care in more detail.
What to Expect from Maintenance: Ho Shi and Audrey will advise on home care, such as our Velvet Smooth anti-frizz range, to help results last.
3. The Shape Family: JK Volume and JK Perm
The Transformation: Not everyone wants smoother hair. Some clients want more body, bounce or curl, but with healthier-feeling hair.
Service Breakdown: Here is how the two differ:
- JK Volume: “For clients who want reconstructed and healthier-looking hair while maintaining or creating body, bounce, movement and volume.” It is ideal for fine or limp hair that collapses in humidity.
- JK Perm: “For clients who want reconstructed, healthier-looking hair together with movement, shape, softness and a customised perm effect.” As a perm salon singapore clients choose for damaged or coloured hair, we explain when a JK Perm suits you better than a standard digital perm in Digital Perm vs JK Premium Perm. Standard perms remain on our perm menu, for example the Ladies Digital/Airy Perm at $250–$350.
Styling Trick: For JK Perm waves, apply curl cream to damp hair and diffuse on low. For JK Volume, rough-dry with your head upside down, then smooth only the surface.
Tip for styling in SG weather: Meteorological Service Singapore notes that humidity “frequently reaches 100% during prolonged periods of rain” [1]. Keep a light leave-in at work to scrunch waves back into shape.
What to Expect from Maintenance: Before any perm, we perform an elasticity check. If you are also planning colour, the AAD advises you to “perm or relax your hair first, and do it two weeks before you color your hair” [4].
4. JK Straightening: The Most Controlled Finish
The Transformation: For clients who want a straighter, sleeker look but are wary of the flat, stiff results they associate with traditional rebonding.
Service Breakdown: JK Straightening is “for clients who prefer a straighter, smoother and more controlled finish while improving the overall appearance, shine, weight and manageability of the hair.” Clients who want permanent pin-straight results may still be better suited to our soft rebonding (ladies, $200–$300). Audrey will explain the trade-offs at consultation. For a complete new look, JK can also be paired with a cut as part of a planned hair makeover singapore package.
Styling Trick: Straightened hair shows every kink from hair ties. Use a soft scrunchie or claw clip instead of tight elastics.
Tip for styling in SG weather: Blot sweat at the hairline rather than rubbing it, because this is where new-growth texture shows first in humid weather.
What to Expect from Maintenance: As your hair grows, new growth returns to its natural texture, and your stylist will plan the next service around it.
