Great Product!
I get keratin treatments in the salon every few months but as I am currently deployed I do not have the salon option.  I emailed this product to my hair stylist in the States before purchasing it and she said it looked like a good product.  I had a friend help me apply it to make sure it was applied evenly and the process was very easy from start to finish.  I am not sure if the ingredients of the treatment have changed but neither myself nor the person helping me had any issues with burning eyes, coughing, etc and we were working in a relatively small (14x6) space with one window which does not fully open.<br /><br />As far as the results they turned out great.  I am African American so my hair texture is pretty course and it has been almost 5 months since my last treatment so I had almost 4 inches of new growth.  My roots are smooth and straight and my hair is bouncy, shiny, and soft.  The results are almost identical to the salon results although I cannot currently vouch for how long they will last.  Either way, I have enough of the treatment left over for at LEAST 3-4 more applications so at $40.00 (total including shipping) for 4 applications vs. $175+ at the salon this product is well worth it!
