My husband and I used to both love Pantene 2-in-1 shampoo however, something happened recently where whenever he used the product, his scalp would start itching and breaking out in red marks. I'm not sure if he developed an allergic reaction to the product suddenly or if Pantene changed their formula but he is now able to only use it once in a while or he has a sudden break out. This was somewhat disappointing since we both liked the product. It smells good and was effective on both of our hair types (I have baby fine straight hair and his is straight but a bit more coarse). I can't honestly say anything bad about the product itself, just the reaction that he's having to it. I wish I could find out somehow if they changed their formula or if this is a problem that he's just having a reaction to it. Overall, I can still use the product and I do however, I'm a bit reluctant to use it as often since I'm not sure if whatever issue he is having will become an issue for me so I'm using it more sporadically than I used to. Effectiveness It is very effective on cleaning my hair and making it feel silky. Scent We both really like the scent!
