Keratin Treatment · Koreatown, Los Angeles

Smooth, frizz-free,

A keratin treatment smooths the hair cuticle to cut down on frizz and add lasting shine, making everyday styling faster and more manageable. At ONIS, it's paired with our own conditioning process to keep hair healthy through the treatment.

Less frizz, less time styling.

Keratin treatments work by coating and smoothing the hair shaft with a protein-based formula, sealed in with heat. It doesn't chemically straighten hair the way a perm does. Instead, it reduces frizz and puffiness, making natural texture easier to manage and cutting down blow-dry time significantly.

It gradually fades out over a few months as hair grows and is washed, rather than growing out at the root the way color does.

Consultation first, always.

Hair that's already color-treated or chemically processed needs a different approach than virgin hair. We assess hair condition and history before recommending a keratin treatment, and adjust formula strength and processing time accordingly.

Is a keratin treatment the same as hair straightening?
No. It reduces frizz and smooths texture, but it doesn't fully straighten curly or wavy hair the way a straightening perm does. Your natural pattern stays, just smoother.
How soon can I wash my hair after?
Most formulas require waiting 48 to 72 hours before the first wash, so the treatment fully sets. We'll confirm exact timing based on the formula used at your appointment.
Is it safe for color-treated hair?
In most cases yes, but it depends on how recently and how heavily hair has been colored or bleached. We evaluate this at consultation before recommending a treatment plan.
