Can finasteride cause dry, itchy scalp?

finesteride doesnt cause itching in our practice we use restorsea spray (fish enzyme to help dry scalp) to combat this and give all our hair loss patients a topical steroid a few times a week. i suggest seeing an expert as this is likely not related to hair loss. A cell also helps with the itchiness Best, Dr. Emer.

Despite what the other doctors might say, there actually are some side effects that come along with Finasteride for some people.Many users of Finasteride have been known to report various side effects after using the product, which are the result of hormone imbalances caused by standardized dosing of those medicines in oral form, such as scalp irritation you are experiencing. It is also worth noting that any
medicine that actually can make changes inside your body, are required
under the FDA to be available by prescription only. This therefore means
that it is not possible for anything that does not require a
prescription to cure or prevent hair loss or regrow thinning hair. Thus,
a personalized medicine will be the best choice because instead of a
"one size fits all" approach, you will be taking something which is
truly catered to your body's needs.
The number one first step I recommend is a comprehensive consultation with a hair regrowth specialist who will perform lab tests to determine  the underlying cause of your thinning. Without labs, no-one can really know what your true cause is and any treatment will be temporary at best. From here, you can receive the best treatment for your case.
The treatment is out there. Good luck on your search.

No, Finasteride typically doesn't cause any scalp irritation. Have you switched up your shampoo? I would consider trying  the shampoo called Nioxin number 1 or 2.
