I also had significant hair loss for a couple of months for the first time after a bad flare. I had used Prednizone and upped my Asacol dosage while in the flare. I started taking the biotin vitamin, and that helped some, but my hair really didn't get back to normal until I cut my Asacol dosage back down again. I am working harder to stay in remission by taking a probiotic (Digestive Advantage purple box), altering my diet to cut down on fried foods, alcohol, and sweets, and eating spinach and sunflower seed butter on a regular basis. This has all really helped me to stay in remission, and I am hoping to cut down the Asacol (slowly) even more. I'm glad to have my hair back to normal; it can give you quite a scare, at the time, when you don't know why it is happening!
