Japanese Hair Treatment was quite a rage in New York City in the 2000s. For women who were tired of their curly and frizzy hair, this new style came as a blessing. And it would almost seem like a miracle. Women would walk into a salon, pay 150 to 800 dollars on chemical hair treatment and come out with super sexy, long and sleek hair. The best part is that the hair would always remain straight; it never grew out or changed its source. Since then, its popularity kept shooting up.

How Does It Work:

Japanese Hair Treatment involves the usage of chemicals such as calcium hydroxide that relaxes the curls and makes it soft and smooth. First your hair shall be separated in sections.

After that the hair is blow dried and flat ironed. After this your hair will look perfectly smooth, straight and long. But if your hair is way too curly, the entire process shall be repeated.

How Long Does It Last and What Is The Cost?

This treatment has been advised for hair that is already in good quality.

The cost of this will be around 150 dollars in Queens, New York and 400 dollars in Manhattan. Although it is expensive, the results are equally effective.
