I suffered from extremely dry scalp which contributed to shedding and itching no matter how much moisturizer or conditioner I used.
I started using these 4 things and I no longer suffer (A bit pricey but worth the results)
-Fish oil supplements
-Alove Vera Gel supplements
-Aloe Vera Oil (the kind that comes with a dropper to apply directly to scalp)
-Tea Trea Oil (occasionally for flare ups)
The oils are also great to rub on your skin to prevent and soothe eczema breakouts!
Good Luck!
