It can be annoying to have an itchy, dry hair after using Neutrogena shampoo. If these symptoms get better, you might want to switch to a Neutrogena shampoo that is made especially for sensitive scalps.
Neutrogena Skin Therapy Anti-Dandruff Itchy Scalp Shampoo, for example, is made to help with dandruff-causing itchy, flaky skin, and it starts to work after the first use.
Adding a moisturizing conditioner to your routine can also help restore the moisture in your hair. If you want to calm down, look for items that have ingredients like aloe vera or tea tree oil in them.
Also, when you wash your hair, don't use hot water because it can strip the skin of natural oils, making it even drier.
