Please help with my eczema

Is been a year that i got diagnosed with eczema. When my doctor told me that i have eczema i was surprised 😱 because im 37 year old and i have never experienced any skin problem. He said is normal for people of my age to get it. He prescribed me dupixent which is an injection that i put in my body every 2 weeks. But now even my hair is falling due to my eczema, because my scalp is also itching. I tried Aveeno, Cerave, banana oil, and nothing.

Anyone here have experience this??
