Large S-Wave Digital Perm for Heavy Long Hair in Bangkok
This Oilly Hair Salon Bangkok case was designed for heavy, naturally straight-falling hair with medium-to-coarse strands. The goal was to create large natural waves, add volume, and bring more definition around the face while keeping the finish soft and refined.
The finished design combines a layered haircut with a large-wave digital perm, creating natural movement through the mid-lengths and ends without turning the result into tight curls.

Before, Wet Curl Pattern and Finished Result

This case used a digital perm technique with salon products from Taiwan. The service was planned around a large, natural wave pattern rather than a tight curl finish.

The client’s hair had natural weight and fell straight, with medium-to-coarse strands. The starting shape was smooth and long, with limited wave movement through the mid-lengths and ends.
Starting Point
The client’s hair had natural weight and fell straight, with medium-to-coarse strands. The starting shape was smooth and long, with limited wave movement through the mid-lengths and ends.
The requested direction was a large-wave digital perm that would build volume through the lengths and make the face frame appear more defined while keeping the curl pattern relaxed and natural.
Design Direction
Oilly Hair Salon Bangkok designed the look around a soft S-wave perm with large natural waves. The aim was movement that felt elegant, wearable, and naturally flowing on long hair.
Before the perm, the haircut was refined into layers. This helped prepare the shape so the wave pattern could sit more beautifully and support a lighter, more dimensional silhouette.

Finished Result

Home Styling
The finished digital perm can be styled in simple ways at home, depending on how relaxed or unified the client wants the wave to look.
Natural Air-Dry Method
Apply curl cream and allow the hair to air-dry naturally. Once dry, gently use a wide-tooth comb to soften the shape into relaxed, natural waves.
Hand-Twist S-Wave Method
Twist or coil the hair by hand in one consistent direction. This encourages the waves to move together more smoothly, creating a softer and more unified S-wave finish.
The same digital perm can be finished in different ways at home—from relaxed, air-dried movement to a smoother, more unified S-wave shaped by hand.
