Sudden hairfall, hair thinning & itching

My over-caring tendencies since 2020 to keep the virus at bay, made me shampoo my hair literally everyday of the week,especially on the days I went to office. For a brief 2months back in 2020, out of fear of the virus even having the capacity to stay on hair strands, I was applying a disinfectant solution directly to my hair, which, I eventually stopped, on the advice of my family members. Ever since then, I have been shampooing literally regularly. Now, since Feb 2022, I have been noticing hairfall increasing in volume and certain portions of the scalp becoming a little barren. But, I was one with               dense hairgrowth all these years until Feb. In my family, I don't see anyone with balding problem as such though my father now has the entire front portion thinned and the crown portion having no hair as well. But, he happens to be above 60years. So, what could be the reason and how to have the hair back. Really worried. And which treatment should I go for- Allopathy or Homeo?
