I think I've tried them all. I buy them because of sensitivity on my scalp, as they are cheaper than head&shoulders. If I don't use a strong cleansing shampoo, flakes are formed and my skin becomes irritated (I think it's a type of dermatitis, but it can be combated with an anti-dandruff shampoo). This particular one always makes me "worse". Even during periods when my skin is fine, 2-3 washes with this shampoo and I have severe dry skin for at least 10 days. Because I also have dyed hair, needless to say, without conditioner they become like straw. The only reason I continue to buy it occasionally is purely because of the price.
