Brazilian Blowout Versus Keratin Treatment Versus Japanese Treatment: What to Choose?
Brazilian blowouts, keratin treatments, and Japanese treatments are hair smoothing treatments with different hair effects.
They are all semipermanent hair treatments, (1) but the result of Japanese treatments is permanent. So, based on the results, Japanese treatments are better.
A Brazilian blowout coats the hair with a preservative solution and keratin, making it shiny, smooth, and frizz-free for about 12 weeks. A keratin treatment infuses hair with heat and keratin to make it strong, protected, and smooth for about 3–6 months. A Japanese treatment changes the structure of the hair with heat and chemicals, making it permanently flat and straight.
Based on the damaging factors, Brazilian blowouts cause hair damage, leading to hair loss, dryness, and breakage. Keratin treatments may also lead to hair damage as they disrupt the moisture content and protein of the hair. Japanese treatments damage the hair by weakening the bonds and creating a visual line between natural and treated hair.
Brazilian blowouts are a sub-brand of keratin. They have similar effects, which are to reduce frizz and create a straight texture. However, years after they became famous, a report emerged stating the presence of formaldehyde (a carcinogen) in these treatments, which decreased their popularity.
Apart from straightening hair, Brazilian blowouts also make it easy to blow-dry hair, unlike Japanese treatments. Keratin hair treatments may still hold curls and waves; their results last about 4 months.
Japanese treatments create pin-straight strands. This treatment doesn’t fade eventually and will remain straight until the hair is cut off completely.
Brazilian blowouts, keratin treatments, and Japanese treatments are suitable for different hair types with different costs and where they can be done. Consult a styling expert before choosing any.
