Getting smooth, shiny hair is a goal many people strive for, but it can often be difficult to achieve without damaging your precious locks. That’s why tannin straightening has become so popular in recent years. It leaves hair smooth and shiny without damaging it. Tannins, which are natural substances, work by creating a protective layer on the hair, making it more supple and manageable. What’s more, this treatment is suitable for all hair types and contains no harmful chemicals.
What is tannin smoothing?

Tannin straightening is a hair straightening technique that uses tannins, natural polyphenols found in certain plants, as its main ingredient. These compounds have the ability to restructure hair fibers, making them more resistant and less prone to damage from heat or chemicals.
How does tannin smoothing work?
Tannins penetrate hair cuticles, forming a protective envelope around each hair fiber. This action restores hair’s strength and elasticity, while making it easier to detangle and style. The result is a semi-permanent smoothing effect that generally lasts several months.
The benefits of tannin smoothing
Visit Tannin smoothing offers many advantages over other smoothing methods, including :
- Natural and safe: Unlike aggressive chemical treatments, tannin straightening does not damage hair and poses no health risk.

How does a tannin smoothing session work?

A tannin smoothing session generally consists of several stages:
- Washing: The hairdresser begins by washing your hair with a specific shampoo to remove impurities and prepare the hair fiber to receive the treatment.
- Product application: The hairdresser then applies the tannin product strand by strand throughout your hair, taking care to distribute the product evenly.
- Application time: The product is left on for a set time depending on the nature of your hair (generally between 30 minutes and 1 hour).
- Rinsing: Once the application time has elapsed, the hairdresser rinses your hair thoroughly to remove any excess product.
- Drying and straightening: Finally, the hairdresser dries and straightens your hair using a hair dryer and straightening iron to set the treatment and reveal all its shine.
