Two techniques share the limelight: Brazilian straightening and tannin straightening.

What are the differences between tannin straightening and keratin straightening?

Tannin straightening involves restructuring the proteins in the hair to make it smooth, while Brazilian straightening relies on the injection of keratin proteins into the hair fibers to make them smooth.

Both methods are natural but rely on different compounds. Let’s take a closer look.

note that both methods need the best flat iron for 4c natural hair.

What is tannin smoothing?

Tanninoplasty is a hair treatment that not only smoothes the hair, but also repairs it, moisturizes it deeply and restores its vitality.

Tannin straightening is much less aggressive to your hair and has fewer side effects than many other hair straightening techniques.

This method is performed only by a qualified person and lasts about 2h30. Prices vary between 200 and 300 dollars.

👉🏾 Which shampoo to use after a tanino hair treatment ?

A tannin hair straightening is usually done as follows:

  • The hair is washed with a clarifying shampoo
  • After drying, we apply the mixture containing the tanning agent strand by strand. We massage the hair to make penetrate the product in depth
  • Leave on for 30 minutes to 1 hour
  • Activate the product with a straightening device
  • Rinse thoroughly several times

Tannin straightening is the perfect treatment for those who do not want to use chemicals on their hair or who have very sensitive hair.

In addition to making the hair smooth for about 6 months, it nourishes the hair, makes it silkier, shinier and more resistant.

What is the Brazilian straightening?

Brazilian straightening also allows you to obtain completely smooth hair without having to damage it, because this technique does not contain products that can harm the health of your hair.

The keratin used for this type of treatment is a protein similar to that produced naturally by the hair.

Unlike some straightening methods that damage the hair, keratin straightening gives it a natural complement.

What are the differences between tannin straightening and Brazilian straightening?

You still hesitate between the two methods? Let’s see their differences a little more precisely.

Very different compositions

First of all, tanninoplasty is a technique that uses only natural ingredients. The tannins are of vegetable origin and most often come from grapes.

Brazilian straightening also uses natural ingredients. It is based on keratin, an element naturally present in the constitution of the hair.

However, it happens that some preparations for Brazilian straightening contain formalin, a potentially harmful element. This is why I advise you to always check the composition of a product before applying it to your hair. Rest assured, most preparations for Brazilian straightening are formaldehyde-free.

Proven effectiveness

Tannin straightening and Brazilian straightening both have very satisfactory results over time. Both treatments allow a smoothing during 3 to 6 months depending on the maintenance of the hair.

An interesting point about tanninoplasty is the possibility of obtaining different degrees of smoothness. You can choose between completely straight or slightly wavy hair. I prefer to warn you that this type of operation requires the intervention of a specialist in straightening.

Concerning afro hair, both methods offer satisfactory results for a long-lasting straightening. They have in common an immediate effect and a long duration of action. Note that for this type of hair nature, it may be necessary to use a straightening iron for 4c hair.

The differences between Brazilian straightening and tannin straightening are mainly related to their composition.

Does tannin straightening damage the hair?

As we have seen before, the ingredients needed for a tannin straightening are of plant origin.

In addition to being a natural preservative, tannin contains antioxidants and anti-inflammatory properties. These elements make tannin a great ally for healthy hair.

Tannin straightening gives a new shape to hair fibers without any damage.

This organic straightening process reduces waviness, increases hydration and shine, and makes the hair smooth, soft and delicate.

As you can see, far from damaging the hair, tannin straightening is a natural and revitalizing treatment for all hair types!

Which straightening is the most natural?

Straightening your hair should never have a counterpart in terms of hair health.

On the contrary, with the methods developed in recent years, straightening is an opportunity to provide additional care for hair in perfect health.

Straightening with tannin

This biological method brings suppleness, hydration and vitality to the hair without altering its internal structure.

Tanninoplasty can be used for straight, curly or even natural hair, colored or natural, oily or dry.

Unlike keratin straightening, tannin straightening keeps hair elastic, healthy and shiny. Dry hair type 4b or 4c benefits greatly from the moisture and nutrition it provides. For more information, check out my review of tannin straightening for african-american hair.

The procedure takes a few hours and the results can last up to 6 months. The price varies between 200 and 300 dollars. The icing on the cake is that with tannin hair straightening, you benefit from an environmentally friendly treatment!

Hair exoplasty

Exoplasty is a non-invasive hair straightening treatment that is non-toxic and does not contain harsh chemicals.

The main ingredient used is a collagen protein. The nanoparticles from the treatment penetrate the hair and rebuild it, eliminating waves at the same time.

This process does not modify the structure of the hair, so the results obtained are more natural than keratin straightening.

Another advantage is that it is possible to choose the intensity of the treatment, such as smoothing curly hair, relaxing waves or straightening completely.

The treatment in the salon lasts from 2 to 5 hours. The result lasts 3 to 5 months and the price is usually 200 to 300 dollars.


Enzymotherapy works with a mixture of enzymes and tannic acid. It is an entirely biological method.

In some treatments, argan oil and vegetable collagen can also be used.

Enzymotherapy rebuilds without modifying the internal structure of the hair. It softens, repairs, moisturizes and gives shine. The hair becomes silkier and more manageable.

As with exoplasty, you can choose the strength of the straightening at your convenience. It is also the perfect technique to give volume to fine hair.

It takes about 2 hours to apply, the results can last up to 6 months and the price starts at 200 dollars.
