Have you used the Brazilian Hair Straightening / Blow-Dry Home Keratin Treatment from Amazon?

[nobodysfool]

I have read lots of threads about this kit and people seem to rave about it to reduce the frizziness in hair but I remember reading a while back that some contain formaldehyde and I concerned that this one contains it. I have read the ingredients but am unsure if formaldehyde goes by other chemical names?
Just worried I'll do damage to myself for the sake of frizz free hair.
Any ideas?

I have a colleague who swears by them. Only thing is that it takes a loooong time to do the treatment!

Do u know if it makes her hair poker straight?

It's fairly straight but not poker straight like the way Japanese hair straightening does.

I use them every now and again. Takes around an hour and a half to get do the treatment, including washing and rough drying hair, putting the stuff on, waiting 20 mins, then drying and straightening my hair. The worst bit is leaving it for three days without washing, although last time I did it I washed it off after two days and it seemed to last almost as long as normal - maybe two months instead of two and a half months.

Gah. I know this is a zombie thread but the link at the top is broken (now links to a completely different product) and I need to know what the wonder-product is? Can anyone from the old thread remember please?
