The 7 Best Shampoos After Tannin Straightering

Today we present to you the top 7 of the best shampoos after smoothing with tannin.

Tannin straightening or taninoplasty is a treatment that coats the hair fiber and straightens the hair with products containing tannins and other natural products.

It lasts about a quarter or 3 months.

Given the fairly high price-performance ratio of tannin smoothing products, it is better to try to maintain the result a little longer as possible.

But effective maintenance and smoothing that lasts requires the use of suitable shampoos. So what are the best shampoos to use after a tannin straightening.

What are the benefits of tannin smoothing?

Tannin is a substance that is most often found in the skin of certain fruits or plants such as grapes, chestnuts and oak.

Smoothing is designed only from natural products and is therefore appreciated for its moisturizing and nourishing properties.

Your hair, in addition to being softened and softened, will be much stronger and more resistant.

How to maintain a smoothing with tannin?

You managed to soften your mane and you are more than satisfied with your hair. But for the result to last the longest, it will have to be maintained.

Indeed, the maintenance of smoothing with tannin goes through the choice of a suitable shampoo that contains all the active ingredients and surfactants compatible with smoothing with tannin.

The shampoo to be preferred must contain exclusively vegetable oils and natural active ingredients known for their fortifying, softening and moisturizing effects for Afro hair.

The choice of a good shampoo without forgetting good maintenance practices will allow you to prolong the effectiveness of the tannin treatment and keep your hair smooth for up to six months.

What are the types of shampoos to avoid after a smoothing with tannin?

Cleansing cosmetic products most often contain sulphate which appears on labels under the name of:

  • Sodium Laureth Sulfate.
  • Ammonium Lauryl Sulfate.
  • Sodium Lauryl Sulfate.
  • Disodium Lauryl Sulfosuccinate.
  • Disodium laureth sulfosuccinate.
  • etc.

These negatively charged surfactants are used for their foaming properties.

They will give you the impression of having a clean scalp , but the sulphate will leave your hair damaged, weakened, much more brittle.

Also, sulfate tends to frizz the hair , which is definitely not good for your tannin straightening.

Apart from sulphate, shampoos containing paraben, salt, mineral oils or silicone are to be avoided.

In addition to being harmful to your hair, just like sulphate shampoos, these chemical additives are irritating, allergenic and drying.

These chemicals will certainly alter the result of your straightening by having a chemical reaction with the tannin.

What are the shampoos to favor after a smoothing with tannin?

Vegetable keratin and castor oil shampoos

For the maintenance of hair straightened with tannin, vegetable keratin and castor oil are at the top of the list of recommendations.

Castor oil is naturally concentrated in keratin and its two components are known to bring suppleness and vitality to the hair.

They also fortify the hair fiber and repair damaged hair.

The vegetable keratin will create a protective barrier that will allow the tannins to act in depth and its smoothing effect will last on your hair.

Sunflower oil shampoos

Sunflower oil has excellent properties for tannin straightened hair. It lightens the hair and limits the formation of frizz.

Sunflower oil therefore makes it possible to prolong or amplify the effects of smoothing with tannin while leaving your hair soft, silky and shiny and facilitates styling.

Low shampoos

The low shampoos that are increasingly appearing in supermarkets are shampoos that respect the scalp .

Inspired by no-poo, low shampoos are totally devoid of sulphates, silicones and parabens in order to wash the hair gently while providing it with everything it needs to be healthy.

Low shampoos are suitable for tannin-straightened hair because of their composition devoid of chemical elements that can disrupt the tannic active ingredients that have made it possible to coat your hair.
