Hair loss *without* WEN!

I may have to live on cheaper food for a long time, but I MUST go back to using WEN exclusively for my hair! I recently tried using a mild shampoo as a first cleanse and WEN to condition, after using nothing but WEN for many, many months. My little Scottie dog, Molly, was diagnosed with lymphoma last June, had chemo, and was in remission for seven months, but the first week of March she came out of remission, and started a new round of chemo. Unfortunately, the drug the oncologist chose destroyed her bone marrow, and put her in the ICU with life-threatening neutropenia. She had transfusions and a bone-marrow stimulating drug, and got a little bit better, came home, but relapsed and crossed the Rainbow Bridge last Sunday. The ten day stint in ICU left me with a $5,600 vet bill, so I was trying to economize by skimping on WEN, but I'll be bald in no time at this rate, between the "poo" and stress, so I am going back to all WEN, all the time! Just three weeks of shampoo and my hair is dry, tangled, and breaking with every combing or brushing, and my scalp is dry and itchy as well, and I just can't stand it. I know there are people who can't use WEN, their scalp reacts badly to it and they lose hair, but I'm the opposite, I need my WEN!
