When to buy WEN? NEVER!!!
The Wen by Chaz Dean haircare products are absolutely awful.They kill yor hair...also, the company takes your creditcard information and keeps sending you more without you ordering it.
My hair feels like greasy straw now and don ever get some it in your eyes while you are showering beause it feels like someone is stabbing you in the eye witha brokenpiece of glass!
Also, the "free gift" you get is a comb and it was broken.I had to pay to ship the additional products they charged me for back to the company in order to get my money back.
