What methods are used in Japanese hair straightening?

Japanese hair straightening, commonly known as Japanese thermal reconditioning or Yuko System, involves several techniques to achieve sleek and long-lasting straight hair. Here are some of the primary methods used in Japanese hair straightening:

Relaxing Cream/Solution:

- A chemical relaxing cream or solution, containing ingredients such as thioglycolate or cysteine, is applied to the hair.

- This cream breaks down the hair's natural bonds and loosens its structure.

Heat Styling:

- After the relaxing solution has set, the hair is thoroughly rinsed and dried.

- A flat iron or straightening iron is then used to press and seal the hair cuticles, locking in the straight shape.

- The intense heat helps to reshape the hair and prolong the straightening effect.

Neutralization:

- Once the hair has been straightened, a neutralizing solution is applied to stop the chemical process and restore the hair's pH balance.

- The neutralizer helps to stabilize the hair's structure and strengthen it after the chemical treatment.

Deep Conditioning:

- To replenish moisture and nutrients lost during the chemical process, a deep conditioning treatment is often performed.

- Hair masks, serums, or oils are used to hydrate the hair and enhance its overall health.

Final Drying:

- The hair is thoroughly dried and styled as desired, using a blow dryer and appropriate styling products to achieve a smooth, straight look.

It's important to note that Japanese hair straightening is considered a permanent straightening method and the effects can last for several months. However, it does require specific aftercare and maintenance to ensure the health and longevity of the treated hair.
