Cold Perm for Frizzy Blonde Hair: Defined S-Waves in Bangkok
This client came to Oilly with blonde hair that felt frizzy and no longer held a shape. She wanted more body and natural S-waves, and she wanted the curl to be clearly defined. Her biggest worry was damaging her hair further, so Oilly assessed her hair and ran a strand test before planning the cold perm.

The Brief: Defined S-Waves Without Adding Damage
She wanted more body and volume, with natural S-waves rather than a stiff, set curl. Above all, she wanted the waves to be clearly defined.
She was also worried that perming would damage her hair further. That concern shaped the whole plan: the waves had to come with hair that still felt moisturised and soft.
Hair Assessment and a Strand Test First
Before any decision on the perm, Oilly assessed her hair and ran a strand test. The test shows how the hair responds before the full head is processed, so the plan is based on her current condition rather than on assumptions.
Japanese Perm Solution and Korean Rods
For this cold perm, Oilly used a perm solution imported from Japan together with modern perm rods from Korea.
These rods help the waves stand out with more dimension while keeping them soft rather than stiff, which suits a natural S-wave finish.
Wrapping Direction Creates the Definition
Clear waves depend on more than the rods. The wrapping direction guides each section into a distinct, standout wave, and getting it right takes real experience.
Oilly’s main goal stayed the same throughout: the waves she asked for, without adding damage beyond her starting condition, and hair that remains moisturised and soft. A perm is still a chemical service, so the result is always planned around the individual hair rather than promised in advance.
Who a Cold Perm Suits
A cold perm is a good fit if you don’t like blow-drying, want hair that looks fuller and can be left natural, and want something easy to style after washing.
Result: Defined Natural S-Waves
The After photos show defined S-waves running through the long blonde lengths, replacing the frizzy, mostly straight hair in the Before photo.
After the service, Oilly showed her how to care for and style her waves at home, so day-to-day styling stays simple.
