Great product

I think this is a great product. I followed instructions to the 'T' and I like what I am seeing. I have wavy frizzy medium to fine hair, so I left the product on only for 45 minutes. The smell was nice - no obnoxious fumes - I keep the windows open and had a fan just moving the air around, so it was not like the product in salons that are just so irritating. I just applied it and the result so far is awesome. It will be interesting to see if the results last. I'll keep you posted.
