For reducing sweating on the head and scalp in male patients, there are several supplements and medications that have shown potential effectiveness. Here are a few options:

1. Cannabidiol (CBD): There have been cases where CBD significantly improved symptoms of hyperhidrosis. Cannabidiol may help reduce anxiety-related sweating and is generally considered safe¹.

2. Tannins: Found in black tea and other sources, tannins can reduce sweating by closing sweat ducts when applied topically. They also possess antimicrobial properties, which can help with odor control².

3. Benztropine: This anticholinergic drug has been used to manage excessive sweating, especially when related to certain medications such as antidepressants. Benztropine acts by blocking cholinergic stimulation of sweat glands³.

4. Glycopyrrolate: This anticholinergic is available in both oral and topical forms. It has been effective in reducing localized sweating, including craniofacial hyperhidrosis, when compounded in a topical solution⁴.

5. Oxybutynin: Though primarily a medication, oxybutynin has shown positive results in clinical treatments for hyperhidrosis, including craniofacial hyperhidrosis⁵.
