Hairfall since April 2020. Needs now.

Hello, I live in Mulund East. I had long, shiny,  dense hair. Earlier I lived in Patna ( Bihar). In  bihar I never had major hairfall issues. I shifted in Mumbai last year, and started facing hairfall issues. I am a working girl in MNC company. So I had shift timings issue. So I had no time to do  much care for my hair. Still I managed to do oiling and washing my hair twice in a week. It was manageable also. But after lockdown I faced severe hairfall. I don't what happened to my hairs. 😭 It's falling like hell from root. I tried branded as well as ayurvedic shampoo for it. But nothing is working with me. Currently I am working from home so I am not even exposed to dust or sun. I am having balance diet but due to the shift Issues I am not able to manage my diet on timely. I am going stress theses days in my professional as well as personal life. And this hairfall is just adding more stree in my life. Please suggest me what to do. I don't know what my hair needs now.
