Recommendation for formaldehyde free keratin treatment ?

[Serendipitysays]

Hello,
I have been looking around to get the Brazilian keratin treatment done . Got it done twice at the le papillon ... But now given the harsh realities of the products used containing formaldehyde - a potential carcinogen , I have to think twice.
I did read that the new Keratin products are now formaldehyde free .
Does any one know of a reputed saloon who uses the safe formaldehyde free products ?
I would be happy if someone has a recommendation that's tried and tested !
