Trader Joe's Tea Tree Tingle Shampoo with Peppermint??
Dread Products
Personally, I have talked to multiple other members on here, and from personal experience, it will eventually cause quite a build up.. It may be ok to use on occasion, but I wouldn't suggest it for long term use.. You may not have any problems with it, but like I said, from those I have talked to, and from what I have experienced, when you first begin using it, it seems ok, but through time it definitely caused a build up for me... So, I guess you could try it out and see how it works for you, but be a little cautious.. If you look around enough on this forum, you will find some articles on some of the problems people have had with it. (once again, I am not saying to not use it.. Just would be good to read about them, so you know what to look for.)
