Short answer: XINZI Perm Liquid is a liquid perm product usually used for cold perms, but with the right softening technique and temperature control it can create a Korean Digital Perm — large, bouncy, natural waves. The 8-step SOP runs: soften, elasticity test, rinse thoroughly, wind and heat at 90-110°C, cool, neutralise, unwind and rinse.
Its advantage is an essential oil and keratin protein formulation that helps prevent the hair from drying out during digital heating.
The 8-Step Technical SOP
| Step | Salon Process | Technical Notes | Time |
|---|---|---|---|
| 1 | Wash & Preparation | Wash the hair with shampoo (no conditioner). Towel to 70%-80% dry. Analyse the level of structural damage to decide the softening time. | 5 minutes |
| 2 | Apply Agent No. 1 (Softening) | Apply Agent No. 1 to the target area, slightly away from the scalp. Tip: for damaged hair, mix in a little keratin treatment before applying. | Healthy: 20-30 min; Damaged: 10-20 min |
| 3 | Elasticity Test | Pull 3-4 strands. If the hair stretches 1.5 to 2 times without breaking, softening has succeeded. If not, add 5 minutes. | — |
| 4 | First Rinse (IMPORTANT) | Must rinse Agent No. 1 with warm water until 100% clean. Do not use shampoo. Towel to 50% dry. This step prevents the hair from burning. | 5 minutes |
| 5 | Winding & Digital Heating | Wind with digital ceramic rods to the size of the Korean wave. Add heat protection paper and connect to the digital machine. | 90°C-110°C (15-20 minutes) |
| 6 | Cool the Rods | Switch off the machine and let the rods cool completely. Do not apply Agent No. 2 while the rods are still hot (it damages the cuticle). | 10 minutes |
| 7 | Neutralisation (Agent No. 2) | Place a neck trough and apply Agent No. 2 evenly over the rods to lock the wave shape permanently. | 10-15 minutes |
| 8 | Unwind & Final Rinse | Unwind the rods slowly and rinse clean with warm water. Apply conditioner or a hair mask to close the cuticle. | 5 minutes |
3 Stylist Tips for Perfect Korean Waves
- Rod size: for a Korean look, avoid small rods. Use medium-to-large rods (e.g. 18mm, 20mm or 22mm) depending on hair thickness.
- Blow-dry method: teach clients how to dry hair at home. Twist the hair outwards or inwards while pointing the dryer heat from top to bottom.
- Lock in moisture after the perm: finish by applying LB-II Ionic Crystal Repair Serum to the ends for maximum gloss and to bring out the wave texture.
