Taking an oil bath after Brazilian straightening hair

The oil bath is without a doubt one of the best solutions to nourish the hair regularly after a Brazilian straightening.

An oil bath on dry or wet hair?

Both solutions are possible and are more or less adapted according to the nature of each hair.

  • On wet hair, the scales of the hair are already receptive, allowing a better absorption of the oil. Some do not hesitate to do it on dry hair
  • On dry hair, the scales are less receptive, but the lack of them favors the solubility of the oil.

I invite you to test both methods and see which one suits your hair type best!

Why do an oil bath before shampooing?

Shampooing is the only way to remove excess oil, otherwise your hair will remain very greasy. Use a sulfate-free shampoo after an oil bath. If necessary, you can wash your hair twice.

In addition to the oils mentioned above, you can use other oils according to your preferences.

Other suitable oils include flaxseed oil, almond oil and castor oil, which is particularly suitable for natural hair.

How to take care of keratin treated hair at home ?

Brazilian straightening is a keratin treatment that requires special care. To have smooth and flexible hair as long as possible, it is essential to use appropriate products.

So how to take care of your Brazilian straightening? Here are some answers!

A gentle shampoo to preserve keratin

Brazilian straightening provides the hair with a significant amount of keratin. This keratin is accumulated in the cuticles to be absorbed gradually.

Conventional shampoos contain substances that are often aggressive to the hair fibers, which can cause the scales to open and the keratin provided by the Brazilian straightening to escape.

This is why sulfate-free shampoos with a neutral pH are so useful. They clean the hair while respecting the hair fiber, without the risk for the keratin treatment to escape.

Regarding the frequency, one to two washes per week is sufficient to keep the smoothing lasting.

To maintain the effect of smoothing longer, you can also use a shampoo enriched with keratin from time to time.

Natural mask after Brazilian straightening

Hair masks make the hair smooth and shiny. They make hair thicker and stronger, preventing breakage or dryness.

Although they are beneficial all year round, they are especially useful in winter when hair tends to dry out. A mask can rehydrate dry hair.

For an even more complete treatment, you can also make a diy protein treatment for 4c natural hair.

The mask with argan and castor oil

Castor oil and argan oil work beautifully together, because they both have comparable properties.

They penetrate deep into the follicles to repair the hair from within. This mask is especially good if you have damaged and natural hair.


  • Mix argan oil and castor oil in equal amounts and apply generously to your hair, starting at the roots and working your way to the ends
  • Massage for a few minutes and wrap your hair with a small wet towel
  • Leave the mask on for at least 30 minutes
  • Wash and rinse your hair

Coconut oil mask

Coconut oil is excellent for hair. Among other things, it allows dry hair to regain all its strength. It also stimulates the scalp and prevents hair loss.

It contains many essential nutritive fatty acids, vitamins, minerals and antioxidants that help to restore vitality to the hair and scalp.

Method of application of coconut oil

  • Before going to bed, heat 1 to 2 teaspoons of coconut oil by hand, depending on the length of your hair, until it liquefies
  • Distribute the coconut oil evenly on dry hair
  • It is recommended to wear a shower cap or towel on the pillow to avoid grease stains
  • Leave the coconut oil in your hair overnight and rinse well in the morning with shampoo. Repeat once a week

How long should coconut oil work?

Coconut oil should be applied for at least one hour as a hair mask. It is best to use it for several hours or even overnight to get the maximum benefit.

How often should I apply a coconut oil hair mask?

As a general rule, applying coconut oil once a month is sufficient. You can adapt the frequency to the condition and nature of your hair.

The olive oil mask

Extra virgin olive oil contains nutrients directly involved in the functioning of hair follicles. A homemade olive oil hair mask is ideal once or several times a week.

Example of application of an olive oil mask

  • Mix a banana with a tablespoon of extra virgin olive oil
  • Add a few drops of essential oil of your choice if you wish to perfume the mixture
  • After applying the mixture to your hair, massage it in for a few minutes
  • Leave it on for at least 30 minutes, wrapped in a warm, damp towel or cling film to prevent it from dripping onto your hair

How to care for hair after brazilian blowout ?

Although the use of quality products is essential to maintain a Brazilian straightening, some simple daily habits can also extend its effect significantly especially after a keratin treatment at home for african american hair.

Adopt a silk pillowcase

Silk fibers are less absorbent and much finer than cotton. Its texture reduces friction between hair and skin, minimizing the appearance of brittle hair and frizz.

This results in smoother hair. In addition, the structure of silk is very similar to that of human hair, making silk one of the softest materials for our hair.

Do not tie your hair up

Leave your hair loose and uncombed for a few days after the keratin treatment.

As the keratin is not yet fully absorbed, tying your hair up in a ponytail or using a pin can disrupt the absorption of the treatment.

To tie your hair, wait at least two or three days and then start using a gentle hair tie for short periods.

Also, try not to tuck it behind your ears!

Use a suitable straightener

Yes, it is possible to use a straightening iron occasionally after a Brazilian straightening! Its use may become necessary when the effect of straightening begins to fade after several months.

To choose the right device, you must consider the nature of your hair. Not all hair reacts the same way to the use of a straightener.

natural hair is more sensitive than other hair types and requires special attention. If you need more information on this subject, I invite you to consult my guide to choose the best electric hair brush straighteners for short natural 4c hair.

If you have thick hair, you should adapt the temperature or use a steam straightener.

Use the right shampoo

If possible, use a shampoo and conditioner enriched with keratin.

They will help you maintain your hair better and keep it straight for a longer period of time.

It’s best to choose a sulfate-free shampoo.

The key is to try not to use harsh shampoos after the treatment, as they may strip your hair of some of the treatment.
