I went to COSCO this weekend , there isn't any product from l'Oreal like 负离子烫药水. I saw some in the Jean Coutu near Concordia last week, unfortunately, I didn't copy the English name of 负离子烫药水.You can find it near the colorants shelf.
I am looking for 负离子烫药水 too. I went to Jean Couto to look for it today. But I do not know how to say it in English. Is there anybody can tell me how to say 负离子烫药水 in English? Thank you!
