Shampoo help!!!

Kaylin

I’ve always had issues with my scalp being sensitive to products but ever since my son was born it’s gotten so unbearably worse. My scalp is greasy and at this point I’m not sure if it’s dry skin or product buildup but it’s making my hair look nasty so I don’t even bother more than a messy bun cause my scalp is so itchy and nasty feeling. Any recommendations???
