I started to use WEN hair care product system and within a couple weeks started noticing I was losing hair. I have really thick hair so I didn't think anything of it right away but then it was like globs of hair in the shower daily. It started to hurt just touching my head, brushing my hair was painful and more and more hair was falling out. I tried to call and cancel my order to which they never did so I ended up canceling my card. They still sent out another shipment even without me paying for it and sent an invoice I refused to pay. Now I am in collections and being sued for not paying for a product that I lost hair on. I switched products and within a few days my head was back to not being painful and no more hair loss. This product sucks!
