Being more of a holistic-y person, i do deal with a number of people with allergies, and am looking to make my treatments as hypoallergenic as is practical. It's a very useful mention that not all formaldahyde allergics are allergic to TSF.
I'd still like to be able to look at TSF-free versions and i'm not too sure where to start, other than reading all the lists of ingredients!
I did think i remembered reading somewhere that formaldahyde can cause yellowing of the natural nails - is this true?
I am also aware that (rightly or wrongly) there are people who wish to avoid these particular ingredients. Is there anything else about them it might be useful to know? Or is there a good source of information on this subject anywhere at all (internet, book, etc)?
Thanks for the help :thumbsup:
