Brazilian Blowout vs. Keratin Treatment — What's the Difference?

Difference Between Brazilian Blowout and Keratin Treatment


Key Differences

Brazilian Blowout is a hair smoothing treatment that seals the hair with a protective layer of protein to eliminate frizz and add shine. The treatment is known for its immediate wash-out policy, allowing clients to return to their normal haircare routine right away.
Keratin Treatment, on the other hand, penetrates the hair shaft to infuse keratin, a protein naturally found in hair, which effectively straightens hair and reduces frizz. Unlike the Brazilian Blowout, Keratin Treatments usually require a waiting period before the first wash to ensure the treatment's efficacy.
One of the notable differences between Brazilian Blowout and Keratin Treatment is the formalitydehyde content. Brazilian Blowouts often use a formula that can release formaldehyde when heated, whereas many Keratin Treatments are available in formaldehyde-free versions.
Clients seeking minimal downtime and immediate results may prefer a Brazilian Blowout. This treatment is designed to leave hair more manageable without the strict post-treatment care that Keratin Treatments demand.
Keratin Treatments are favored for their long-lasting straightening effect, making them a popular choice for those with curly or frizzy hair looking for a more permanent solution. The treatment's lasting power, however, comes with a mandatory waiting period before washing or styling the hair.
