Japanese Hair Straightening, also known as Liscio thermal reconditioning, is a popular hair treatment that promises to transform curly, frizzy hair into silky, straight locks.

But is it suitable for black hair?

What is Japanese Hair straightening

Japanese Hair Straightening is a thermal reconditioning process that involves using chemicals and heat to break down the bonds in the hair’s protein structure, resulting in permanently straight hair.

The process typically involves applying a solution containing chemicals, such as sodium hydroxide, to the hair, followed by heat activation using a flat iron.

The result is smooth, straight, and shiny hair that requires minimal styling effort.

Japanese Hair Straightening for Black Hair (Benefits and Result)

For those with black hair or an ethnic hair type, Japanese Hair Straightening can offer several benefits:

  • Permanent straightening: Unlike temporary straightening methods that require frequent touch-ups, Japanese Hair Straightening provides a permanent solution to curly, frizzy hair.
  • Reduced styling time: With permanently straightened hair, daily styling becomes easier and less time-consuming.
  • Increased manageability: Straightened hair is typically more manageable, making it easier to style and care for.

However, it’s essential to consider the potential risks and downsides of Japanese Hair Straightening for black hair.

The treatment may not be suitable for all hair types, and the use of harsh chemicals can cause damage to already fragile or damaged hair.

How long does Japanese hair straightening last in black hair

Japanese Hair Straightening is a permanent hair treatment, meaning the results can last until the hair grows out.

For most people, this can range from six months to a year, depending on the individual’s hair growth rate. Regular touch-ups may be required to maintain the straightened look as new hair grows.

Does Japanese hair straightening damage hair

Japanese Hair Straightening can cause damage to the hair, particularly for those with black hair or an ethnic hair type that is more prone to breakage and dryness.

The chemicals used in the process can weaken the hair’s protein structure, leading to heat damage, brittleness, and breakage.

It is crucial to consult with a professional hairstylist to assess your hair’s condition and suitability for the treatment.

Can you permanently straighten black hair

Yes, you can permanently straighten black hair using methods like Japanese Hair Straightening or chemical relaxers.

However, permanent straightening treatments come with the risk of hair damage and should only be performed by experienced professionals.

Best way to straighten black hair

The best way to straighten black hair depends on the individual’s hair type, condition, and personal preferences. Some popular options include:

  • Japanese Hair Straightening: A permanent solution for straightening curly, frizzy hair.
  • Keratin treatments: A semi-permanent option that infuses hair with keratin proteins to reduce frizz and add shine.
  • At-home heat styling: Using flat irons or blow dryers to temporarily straighten hair. This method requires frequent touch-ups and can cause heat damage if not done correctly.

Keratin or Japanese straightening: Which one is better

The choice between Keratin treatments and Japanese Hair Straightening depends on your hair type, condition, and personal preferences.

Keratin treatments are a semi-permanent option that can help reduce frizz and add shine, while Japanese Hair Straightening provides permanent straightening results.

However, Japanese Hair Straightening may cause more damage due to the chemicals and heat involved in the process.

For those with fragile or damaged hair, a Keratin treatment may be a safer and more suitable option.

Side effects of Japanese hair straightening

There are potential side effects associated with Japanese Hair Straightening, particularly for those with black hair or an ethnic hair type. Some of these side effects include:

  • Hair damage: The chemicals used in the process can weaken the hair’s protein structure, leading to heat damage, brittleness, and breakage.
  • Scalp irritation: Some individuals may experience scalp irritation or allergic reactions to the chemicals used in the treatment.
  • Hair loss: In extreme cases, the treatment can cause hair loss due to excessive damage and breakage.
  • Uneven hair growth: As the hair grows out, the new growth will retain its natural texture, which can result in an uneven appearance.

To minimize the risk of side effects, it’s crucial to consult with a professional hairstylist experienced in Japanese Hair Straightening and to follow proper aftercare guidelines to maintain the health of your hair.


In summary, 4c hair grows upwards due to the oval shape of the hair follicle, which causes the hair to grow in a curved or S-shaped pattern. This shape of the follicle is responsible for the curly or wavy texture of the hair.

Caring for 4C hair can seem challenging, but with the right practices, you can maintain healthy, beautiful, and vibrant hair.
Remember to pre-poo, use sulfate-free shampoo and moisturizing conditioner, deep condition once a week, hydrate your hair every day, use protective styles, trim your ends regularly, drink plenty of water, sleep on a satin pillowcase, protect your hair at night, and limit manipulation.
By following these best practices, you can keep your 4C hair healthy, vibrant, and beautiful.
