How to treat seborrheic eczema?

Welcome! Yes, seborrheic eczema is very common and can be managed beautifully. I suggest using a gentle ketoconazole-based shampoo as prescribed by your doctor, and avoiding heavy, oily hair products which can feed the yeast. Keep your scalp clean and dry, and you'll see a big difference.

My scalp and the sides of my nose are constantly red, itchy, and flaking, and it is making me so self-conscious. Does anyone else feel like the flaking gets worse when they are stressed or haven't slept well? I'm really worried this will never go away completely.

When you have this condition, washing off sweat immediately after your daily walk or gym session is super important, as dried sweat can irritate the flaking skin. Keep your diet clean and cut down on processed foods. Check with your doctor about mild medicated washes that are safe for daily use.

Let's be direct: seborrheic eczema is linked to a yeast that naturally lives on our skin, so normal beauty shampoos won't fix it. You need a proper dermatologist-prescribed antifungal shampoo and topical lotion. Stop experimenting with heavy home oils which actually feed the yeast, and get a professional prescription.
