You've heard of long-lasting straightening and think it might be the best solution to stop battling with your hair every morning? But do you really know all types of long-lasting straightening?
______________
From temporary to permanent straightening
As a reminder, straightening is the act of flattening hair to make its surface smooth. By definition, straight hair is the extreme opposite of curly hair. Why do many women straighten their hair? Because they don't like the voluminous effect of their naturally frizzy or curly hair. Not wanting to opt for a short cut, they then discipline their hair to preserve its beautiful length.
While many of them use heated electrical appliances such as classic straighteners or steam hair straighteners, some take the plunge and opt for a new technique: long-lasting straightening. This is a hair process that will more or less modify the natural structure of the hair to keep it smooth and flexible in the long term. There are two types of straightening: temporary (the lengths will remain straight for 3 to 5 months), and permanent (if the roots are treated every 3 months).
In addition to making hair soft and silky, these straighteners offer a main advantage: saving time! No more getting up early in the morning to spend an hour in the bathroom perfecting your straightening, juggling between hairdryer, brush, crocodile clips and plates. No more checking the weather every 10 minutes to make sure it's not going to rain! Long-lasting straighteners, on the other hand, defy humidity. Fabulous, isn't it?!

Now, you have absolutely no idea which type of straightening to go for. If you have it done at your hairdresser's, they can advise you best. But if you want to buy a straightening kit to do it at home, you need to research the different methods. Fortunately, we're here to guide you! You'll see, each type of straightening has its specificities.
Brazilian straightening, a keratin boost
This is THE straightening that comes up most often when you do a Google search! It's suitable for curly and thick hair. With this straightening, we aim to make the hair more flexible and relax the curls. Previously, this semi-permanent straightening was enriched with formaldehyde, a chemical substance that doubled its effectiveness. Now, hair salons and home kits favor tannin, a 100% plant-based substance. It will coat the hair, nourish it, and add body. How long does it last? 4 to 5 months. Find out here how to perform a tannin straightening step by step.
Advantages of Brazilian straightening:
- Preserves the natural volume of hair
- Anti-frizz effect even in humid weather
- Does not damage the hair fiber when done without formaldehyde
- Leaves hair shiny and silky
Disadvantages:
- Requires regular maintenance with sulfate-free products
- Some Brazilian straighteners still contain formaldehyde (harmful)
- High price in salons (between €150 and €300)
- Must be renewed every 4-5 months
Japanese straightening, or "chopstick" straightening
This straightening is permanent and radical. It will make each hair extremely straight, like chopsticks! Intended for frizzy hair, Japanese straightening is very powerful and surpasses the effects of Brazilian straightening. Its main action is to permanently break and modify the hair fiber by eliminating frizz. So we can't really talk about hair care here. The lengths will remain straight for life, only the roots will need to be maintained every 3 to 6 months. Be careful, this technique is incompatible with highlighted hair.

Advantages:
- Extreme and perfect straight effect
- Permanent result on the lengths
- Total resistance to humidity
- Ideal for very curly or coily hair that is difficult to manage
Henna, the star of Korean straightening
It's the little cousin of Japanese straightening! Less aggressive than the latter but more effective than the Brazilian method, Korean straightening gently straightens the hair fiber thanks to henna. Coupled with thioglycolic acid, it will, as with chopstick straightening, break the natural structures connecting the hair atoms responsible for curls. This is also a straightening that modifies the lengths for life, and where the roots will need to be treated every 3 to 6 months. Note that Korean straightening is the only straightening method that can be done on henna-colored hair.
Advantages:
- Less aggressive than Japanese straightening
- Compatible with henna-colored hair
- Long-lasting straightening effect
- Leaves hair shiny and soft
Tips for post-straightening care
To prolong the effects of your straightening and maintain the health of your hair, a few essential care rules are:
Adapted shampoos and treatments
