I lived in South Korea for a year, which is where I got my first Japanese Hair Straightening. My hair has a very thick wave in the back that is hidden by a layer of straight hair. I have tried the Brazilian Blowout on my hair twice and not noticed any change (and it's more expensive). Since being back in the states, I decided that I needed to find somewhere to get my hair straightened since my own hair stylist doesn't do this. I found Cleo Beauty Salon and it was just like being back in Korea. Mr. Kim and his wife, who run the salon, are both Korean and fabulous at what they do.
I HIGHLY recommend them!!! My hair looks fantastic, and that's saying a lot! It was well worth the $150 and 3.5 hours.
Beware of other salons that want to charge anywhere from $400-900 depending on length and thickness.... I doubt there's a difference and why pay more when Cleo's does a fabulous job! I will most certainly be back to do this again once my roots grow out.
