  1. First, the hair is shampooed three to four times. This removes any product buildup on the hair strands so that the treatment can penetrate the strands better.
  2. Next, the hair is sectioned, and the Brazilian blowout product is applied to each section. The stylist is careful to ensure all hair strands are evenly coated.
  3. To seal in the product, the stylist will blow-dry the hair and then use a flat iron afterward.

A Brazilian blowout’s effects fade away the more you wash your hair, so while you should still shampoo your hair once in a while, you should do so at a low frequency.

Saltwater and pool water with high amounts of chlorine will strip away your locks’ oils, including the protective keratin put on your hair during a Brazilian blowout.

2. DO Use Keratin Shampoos

Though you should avoid getting your hair wet as much as possible after getting this treatment, washing your hair, albeit less frequently than normal, is still part of proper hygiene and hair care.

Frequently Asked Questions

How Different is the Brazilian Blowout Compared to Other Keratin Treatments?

When looking at results, you may see similar outcomes from both treatments. However, a Brazilian keratin treatment uses a milder formula that can be personalized depending on your hair type. 

Also, Brazilian treatment care is more lenient than other keratin treatments, which are heavier on your hair.

Who Are the Best People to Get Brazilian Keratin Treatments?

Everyone can get a Brazilian blowout, whether you have curly, permed, frizzy, color-treated, or straight hair. 

But do note that those with smooth and straight hair should not expect drastic changes in their hair. 

Those with extremely frizzy hair can get the most out of Brazilian blowouts, which can help minimize the frizz and make the hair more manageable.

Are Brazilian Blowouts Permanent?

They are semi-permanent treatments, and they can last up to three months. How long the effects last depends on one’s hair care after the Brazilian keratin treatment. 

Can I Color My Hair After Getting a Brazilian Hair Treatment?

It’s recommended to color your hair before getting a Brazilian blowout treatment. You can get your hair colored on the same day as your Brazilian blowout as long as you do it before the keratin treatment. 

A woman is getting her hair colored in a salon.

If you’re getting color before the treatment, consider getting a hair color that’s a shade darker than your actual color. The Brazilian keratin treatment tends to fade hair dye into a lighter shade.

However, it can also lock the pigment in, leaving a more vibrant color. 

If you’ve already gotten a Brazilian blowout and want to get your hair dyed, you must wait at least two weeks before getting the color. 

Seek the advice of your hairdresser for the best results, and tell them about the treatment before getting your hair colored.

Is a Brazilian Keratin Treatment Bad for the Health?

Most formulas for keratin hair treatments initially contain formaldehyde and methylene glycol.

These two active ingredients help keratin bind to the hair more easily, making the treatment more effective and leaving the hair straighter.

In recent years, there has been more awareness on the adverse health effects of formaldehyde. It is now considered a known carcinogen and a cause of asthma development in children.

Some people can experience eye and nose irritation when they come in contact with formaldehyde.

Thankfully, there have been more regulations on using formaldehyde in hair treatments. In Canada and the European Union, this ingredient is 100% banned. However, it is still permitted in the United States.

If you’re concerned, it will significantly help to talk to the salon or stylist about the chemicals in the formula they use. 

There are hair salons that choose to use formaldehyde-free formulas, while there are those that still use formulas with formaldehyde for more effective results.

Warning: A Brazilian blowout is not recommended if you are pregnant or breastfeeding. Formaldehyde and other chemicals involved in this treatment may put your baby’s health at risk.

Brazilian Blowouts for Shiny, Frizz-Free, Manageable Hair

While providing you with the amazing benefits of a keratin treatment, Brazilian blowouts also offer versatility and leniency regarding what you can do to your hair post-treatment. 

Still, proper aftercare is needed to prolong its benefits and your hair’s protection. 

Brazilian blowout aftercare involves mindfulness, but you have more than your money’s worth in the long run.

With minor hair care changes and the proper tools and products, you can enjoy beautiful, healthy, protected tresses for longer. 

Try out this keratin treatment and see the difference for yourself!
