National Brazilian Blowout Day

National Brazilian Blowout Day, celebrated on August 21, is a unique holiday dedicated to one of the most well-known haircare procedures. The Brazilian Blowout is a keratin treatment that straightens and repairs hair, leaving it smooth, shiny, and manageable.

History

The idea of straightening and enriching hair with keratin belongs to Brazilian hairdresser José Arevalo. In the early 2000s, he developed a technique and formula that quickly gained popularity, especially among Brazilian women who wanted to smooth out tight curls in a single salon visit.

Arevalo’s original formula contained formaldehyde, which produced long-lasting results of up to 6–12 months. As the method gained popularity in the U.S., a formaldehyde-free version was developed, though it was more expensive and slightly less effective.

Today, José Arevalo owns his own company, Arevalo Industria e Comercio de Cosmeticos, which focuses on producing advanced, formaldehyde-free keratin products. In 2014, the idea to establish National Brazilian Blowout Day was born—timed perfectly for the end of August, when many are looking to restore their hair after the summer. An official website for the technique was launched in 2015.

Interesting Facts

1. José Arevalo is often called “the father of keratin” in Brazil.
2. Many Hollywood stars—including Nicole Kidman, Jennifer Lopez, Halle Berry, and Salma Hayek—have used the Brazilian Blowout treatment.
3. The procedure is similar to the Japanese Yuko system, but it’s much faster. The Brazilian Blowout typically takes 45–80 minutes, while the Yuko method takes around four hours.

How to Take Part

National Brazilian Blowout Day is the perfect time to assess the health of your hair after a dry, sun-filled summer.
