What Is Japanese Thermal Straightening?

Also called: Thermal reconditioning, Japanese straightening

Japanese thermal straightening permanently restructures the hair's bonds to make it pin-straight until it grows out — the strongest straightening treatment available.

Japanese thermal straightening (thermal reconditioning) chemically restructures the internal bonds of the hair, then locks the new straight pattern in with precise flat-iron work. Unlike smoothing treatments that coat and fade, the change is permanent — treated hair stays pin-straight until new growth comes in, when only the regrowth needs re-treating.

It is the right tool for strong, healthy hair with significant curl or wave that wants truly straight, wash-and-go results. It is the wrong tool for heavily highlighted or compromised hair, which is why an honest consultation and strand assessment come first. Wearers who want frizz control while keeping their wave should look at a Brazilian Blowout instead.
