Japanese Straightening vs. Vegan Smoothing: Which is Right for You?

Do you have curly, wavy, or frizzy hair that you want to tame? Hair straightening treatments like Japanese straightening and vegan smoothing are popular options. Each treatment has its own unique set of benefits and drawbacks.

In this blog post, we'll explore the differences between the two techniques to help you determine which one is right for you.

What is Japanese Straightening?

Japanese straightening, also known as thermal reconditioning or Liscio by MILBON, is a popular hair straightening method that originated in Japan. The process uses chemicals and heat to break the bonds in the hair and reform them in a straight pattern. The treatment can take several hours and can last up to six months.


  • Provides permanent results for those with extremely curly or wavy hair

  • Reduces styling time and eliminates frizz

  • Can last up to six months with proper care


  • Can be damaging to color-treated hair

  • Can be damaging to hair if not done correctly

  • Can be a lengthy and expensive process

  • Requires strict aftercare to maintain results

  • Can permanently alter hair texture, making it difficult to revert to natural hair

What is Vegan Smoothing?

Vegan smoothing is a newer hair straightening method that uses plant-based ingredients to smooth and condition the hair. The treatment can last up to three months and is a less harsh alternative to Japanese straightening.

The process does not involve the use of chemicals or heat, making it a safer and more eco-friendly option.


  • Uses natural, plant-based ingredients that are gentle on hair

  • Smoothes and conditions hair without causing damage

  • Offers an eco-friendly option for those who are environmentally conscious

  • May use over color-treated hair (Toner recommended after smoothing treatment instead since it fades the color."


  • May not provide permanent results for those with extremely curly or wavy hair

  • May not be as effective in humid climates

  • May require more frequent touch-ups to maintain results

Which is Right for You?

Japanese straightening is ideal for those with extremely curly or wavy hair who want permanent straightening and a more polished look. However, it can be damaging and requires strict aftercare.

Vegan smoothing is best for those with slightly curly or frizzy hair who want a more natural look without damaging their hair. It's a safer, gentler option that uses natural ingredients and offers an eco-friendly choice. However, it may not provide permanent results or the same level of straightness as Japanese straightening.

Consult with a hair professional to determine which option is best for you.


Choosing between Japanese straightening and vegan smoothing is a personal decision based on your hair type, desired results, and lifestyle. While Japanese straightening is a more traditional method and can offer permanent results, vegan smoothing is a more eco-friendly, natural, and less damaging option. Consult with a hair professional to discuss which treatment is right for you and your hair goals.
