welcome to Healthcare Magic.
Your headache problem is less likely due to use of minokem, uproot or amexidil use. In my opinion it is more due to tension of hair growth and hairfall.
In history, you already mention about tension and hypothyroidism
which increase chances of developing anxiety
. Anxiety can present with headache due to forehead muscle spasm.
Same time get examined by general physician to rule out following causes of headache:
• High blood pressure: BP increases during exercise.
• Infection of teeth/ear/nasal cavity
• Visual problem
