How to change from a studious looking person to a Handsome man

Hello I am a man around 25 age. From my school days I have been called to be looking studious type boy then in college and now in my professional circle as well. If I can quote the comments they are like "You look very studious type". Recently a manager who is a female by the way spoke the same lines. I am not sure but all the times it's been girls or females who have spoken these lines be it my classmate or my neighbourhood girls of the similar age or even elder ones. I can remember one day while I was returning by college bus I met with my highschool days girls who I don't know why told "You are still like the same". I came across some social media reels who were commenting being a studious type with some slangs like "Chomu" or other such words with lots of laughing emojis. And as you might have assumed I am single and always have been. I do have many females like teammates currently with whom I converse hours but all of them have called me as bro or bhai. I want to ensure that I don't feel offended by the persons who have commented me this all these years but since it looks like looks really matters to society then I want to have some changes in my looks or my styling.

I wanted to ask how to change their perception. I want to look and be a Handsome man. Is there any professional stylist who can help me here in Bengaluru or if anyone who have successfully transitioned can share their experiences.

Also on a side note to girls- If there a person who looks as a studious one is unattractive if we consider getting in a relationship or marriage. I don't and won't judge anyone for their honest comments or get frustrated or emotional etc but want to know the reality.
