I used once and my hair became dry and frizzy. On top of that they have charged me over $80 in products I never ordered. I returned everything when I checked they received it on March 30,2015 and still have not given my money back. Then they charged $24.94 on 3 /24/15 called CS they said they would return the money. On 4/2/15 they returned $16.95. I called today 4/16/15. They told me they would return the $7.89 and I had verification of pkg was returned. I asked CS when they would return the $39.99 for trial, she told me 4-6 weeks. I said no way I had proof of delivery and she put me on hold then said she would process the return today and I should see in 3-5 days. Big difference. This company is a con and I will never recommend Wen to anyone.
