Japanese hair straightening, also known as thermal reconditioning, is a permanent hair straightening method that chemically alters the hair's structure. This process uses a special chemical solution to break down the bonds in the hair, allowing it to be reshaped into a straight form.
The Japanese Hair Straightening Process:
The process typically involves several steps:
- Application of a Relaxing Solution: A chemical solution is applied to the hair to break the disulfide bonds that give hair its natural curl or wave. This allows the hair to be easily reshaped.
- Rinsing and Sectioning: The solution is rinsed out, and the hair is then carefully separated into sections.
- Drying and Ironing: Each section is dried, then straightened using a hot flat iron. This sets the hair in its new, straight form.
- Neutralization: A neutralizing solution is applied to reform the disulfide bonds in their new, straight configuration. This step is crucial for making the straightening permanent.
- Final Rinse and Drying: The hair is rinsed again and then thoroughly dried.
The result is permanently straight hair, eliminating the need for daily straightening. Note that new hair growth will retain its natural texture.
Key Differences from Other Straightening Methods:
Unlike other straightening methods like keratin treatments, which are temporary, Japanese hair straightening provides a permanent solution. The chemical process involved fundamentally alters the hair’s structure.
Considerations:
- Damage Potential: Because Japanese straightening involves strong chemicals and high heat, there is a potential for hair damage. Proper aftercare is essential to maintain hair health.
- Hair Type: This treatment is generally more effective on naturally curly or wavy hair.
- Maintenance: While the straightening is permanent, new hair growth will need to be treated if you want to maintain the completely straight look.
In essence: With Japanese hair straightening, human hair is permanently straightened using a chemical solution that breaks and reforms the hair's bonds, followed by heat styling to set the straight shape.
