Japanese straightening and keratin treatments both smooth hair, but they do different jobs. Japanese thermal straightening gives pin-straight hair that lasts until it grows out, while a keratin treatment smooths frizz and reduces volume without changing your hair's shape for good. At Revs Beauty Studio, Japanese straightening is $300 and a keratin treatment is $199, based on our current menu.

How Japanese Straightening Works
Japanese straightening is a permanent thermal treatment. It reshapes the hair so that it stays straight, and the result lasts until the treated hair grows out. Because only the new growth at the roots comes in with your natural texture, many people schedule a touch-up on the regrowth rather than treating the full length again. The appointment takes about three hours, so plan to set aside the afternoon.
How a Keratin Treatment Works
A keratin treatment coats the hair to smooth the cuticle, which reduces frizz and makes hair softer and easier to manage. It does not permanently change your hair's structure, so the effect gradually fades. You keep some natural movement, which suits people who want smoother hair rather than a pin-straight finish.

Which One Is Right for You?
- Choose Japanese straightening if your goal is sleek, straight hair and you are happy for it to stay that way until it grows out.
- Choose keratin if you mainly want to tame frizz in humid weather but still like some wave or body.
- Not sure? Book a consultation. We will look at your hair's texture, history and condition before recommending either.
