How did this hair mask straighten curly hair?
A hairstylist friend of mine reached out and said a client's hair got "accidentally" straightened after leaving on this mask for 40 minutes, with no heat applied. I see a lot of amino acids and emollients, don't see any formaldehyde-releasers but I could be missing something. I'm so curious as to how this could have happened with these ingredients! Any ideas?
