Dandruff and an itchy scalp can be quite bothersome, beta. For a natural remedy, try warming a little coconut oil and adding a few drops of lemon juice or neem oil to it. Gently massage this mixture into your scalp before bedtime. Lemon helps clarify the scalp, and neem is known for its anti-fungal properties. Wash it off the next morning with a mild anti-dandruff shampoo.

Ensure you wash your hair regularly to prevent oil build-up, but avoid very hot water. Maintaining a healthy diet rich in zinc and B vitamins can also help from within. If the condition persists even after trying these remedies, it's always best to consult a dermatologist for a proper diagnosis and tailored treatment.

Beti, it sounds like you're really struggling with this stubborn dandruff, and it's completely understandable to feel frustrated when nothing seems to work. Since you've tried many over-the-counter options, let's consider a few gentle, home-based approaches and then what might be the next step.

For a natural remedy, try applying a paste of fresh curd (dahi) mixed with a tablespoon of lemon juice to your scalp about an hour before shampooing. Curd is soothing and a natural probiotic, while lemon has antifungal properties. Massage it in gently, then rinse thoroughly. Also, ensure your scalp isn't left damp after washing, as moisture can encourage fungal growth. However, if the issue is severe and spreading to your face, it's a strong sign to consult a dermatologist. They can properly diagnose the root cause, which could be a specific fungal infection or a skin condition like seborrheic dermatitis, and prescribe a targeted medicated treatment for lasting relief.
