I've been experiencing excessive itching, scalp sweating and hair thinning - can a Ketoconazole 2% w/v Shampoo help?

That combination of symptoms sounds uncomfortable, and it's good you're looking for a solution. A Ketoconazole 2% w/v Shampoo can help if the itching is tied to fungal or dandruff-related scalp irritation, since calming that down often eases hair thinning linked to an unhealthy scalp too. Excess sweating and thinning can have other contributing factors as well, so if things don't improve with regular use, a dermatologist can check for causes like hormonal changes or nutritional deficiencies.
