Coppola treatment - Silky and smooth but ...

I had the Coppola treatment done twice and each time it was really unbelievable. Silky and smooth and lasted exactly 3 months to the day! The only prob was that when the gal did it my eyes would burn and was a bit concerned about that. I would put a cool compress over my eyes but now that I am reading about this aldehyde stuff I would be more careful and look into it more. The other keratin treatment I had recently that was 'all natural' was no where near the results I wanted and only lasted 1 week!! 100 dollars for one week! Forget it. I am going to look into this aldehyde stuff and find out if it really is toxic...you should too...
