I had my 3rd Express Blow Out today and couldn't be happier with the results. I paid $100 plus tip but paid $150 the other 2 times at a very upscale salon. This treatment lasts about 6 weeks depending on how often you wash and if you use the Keratin Complex products with it. My hair is fine but abundant, somewhere between wavy and curly but always very frizzy/fuzzy. I've been growing my hair out for quite some time and it's longer than it's been in probably 15 years, slightly past my shoulers. It took about an hour and a half start to finish. With the Express Blowout, I can just blow dry my hair about half way and let it finish airdrying. That's it! No flat ironing necessary and the result is smooth hair that looks very healthy.
