The 7 best shampoos after tannin straightening

Today, we’re unveiling the top 7 best shampoos for use after a tannin hair straightening treatment.

Tannin hair straightening, or tanninoplasty, is a treatment that coats the hair fiber and smoothens the hair using products containing tannins and other natural ingredients.

It typically lasts for about three months, or a quarter.

Given the relatively high quality-price ratio of tannin hair straightening products, it’s preferable to try to maintain the results for as long as possible.

But effective maintenance and long-lasting straightening require the use of suitable shampoos. So, what are the best shampoos to use after tannin hair straightening?


What are the benefits of tannin hair straightening?

Tannin is a substance commonly found in the skin of certain fruits or plants like grapes, chestnuts, and oak.

The straightening process is exclusively designed with natural products and is appreciated for its moisturizing and nourishing properties.

Your hair, besides being softened and smoothed, will be much stronger and more resistant.


How to maintain tannin hair straightening?

You’ve successfully softened your mane and are more than satisfied with your hair. But for the result to last as long as possible, maintenance is key.

Indeed, maintaining tannin hair straightening involves choosing a suitable shampoo containing all the active ingredients and surfactants compatible with tannin hair straightening.

The preferred shampoo should exclusively contain vegetable oils and natural actives known for their fortifying, softening, and moisturizing effects on afro hair.

Choosing a good shampoo, along with proper maintenance practices, will help prolong the effectiveness of the tannin treatment and keep your hair straightened for up to six months.


What types of shampoos to avoid after tannin hair straightening?

Cosmetic cleansing products often contain sulfates, which appear on labels under names like:

  • 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 may give you the impression of having a clean scalp, but sulfates will leave your hair damaged, weakened, and much more brittle.

Moreover, sulfates tend to curl the hair, which is certainly not beneficial for your tannin hair straightening.

Apart from sulfates, shampoos containing parabens, salt, mineral oils, or silicone should be avoided.

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

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


Which shampoos to prioritize after tannin hair straightening?

Keratin vegetable shampoos and castor oil

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

Castor oil is naturally rich in keratin, and both components are known for providing suppleness and vitality to the hair.

They also strengthen the hair fiber and repair damaged hair.

Vegetable keratin will create a protective barrier that allows the tannins to act deeply, 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 frizz formation.

Sunflower oil helps to extend or amplify the effects of tannin straightening while leaving your hair soft, silky, shiny, and facilitating styling.


Low shampoos

Low shampoos, which are increasingly appearing in supermarkets, are shampoos that respect the scalp.

Inspired by the no-poo method, low shampoos are completely free of sulfates, silicones, and parabens to gently cleanse the hair while providing everything it needs to be healthy.

Low shampoos are suitable for tannin-straightened hair due to their composition devoid of the chemical elements that could disrupt the tannic actives that have coated your hair.

How do you care for tannin-straightened hair?

After tannin straightening, use a botanical essence known to coat the hair.

These include silk protein, argan oil and coconut oil. These plant essences have both smoothing and moisturizing properties.

In addition to protecting the hair fiber, they will leave your hair softer. They will prolong the effects of your tannin straightening.

After tannin straightening, you’ll need to wait three to four days before washing your hair, to allow the tannin to penetrate properly.

You’ll need to wash your hair at least once every two weeks. Use moisturizing masks with keratin or vegetable oils to make the taninoplasty last.

As taninoplasty is a natural smoothing treatment, it does not damage the hair. However, it does tend to make hair drier.

You’ll need to moisturize your hair every day. You can apply coconut oil, silk protein, argan oil, castor oil or jojoba oil.


What you absolutely must do

After straightening with tannin, you should avoid sea or pool water. They contain chlorine, a chemical compound that can affect your straightening.

So remember to protect your hair with a bathing cap. You can use a shampoo suitable for tannin straightening after every swim.

Don’t forget to sleep on a pillow or with a silk or satin cap.

Apply a mask once a week. Use honey, avocado, banana and the vegetable oil of your choice from roots to lengths.

Wrap your hair in cling film and a warm towel. You can also use a charlotte for about ten minutes and rinse.

Finish with a smoothing serum on the lengths to condition them.

You can use a straightening iron on your hair to reactivate the tannin’s properties.

But use the straightening iron sparingly. Don’t forget to protect your hair with a thermal protector before straightening.


In short, to maintain tannin-straightened hair, you need to use shampoos and care products that are :

  • sulfate-free
  • pH-neutral
  • castor oil
  • vegetable keratin
  • sunflower oil

Follow these recommendations to keep your tannin straightened hair for as long as possible!
