I am doing fap like everyday atleast average 4times a days and high record was 7times for approx 7 month. I am addicted to fap for 2 years and starting fap at mid 16, in my mid 17 (1 year later in fapping) my hair density is very low that people point out my hair and my friends taunted me because of hair and my parents get sad because of low hair density at this age, now i am 18 and doing nofap and 2 times nofap 40 days record, now more than 18 days, if i do nofap for like long days does my hair regrow and thick where it was, becomes i have thick hair and lot of hair during late 16 and early 17.
So i am insecure and feel depressed and introvert (don't know how to talk to people)
So i do fapping.
So three things that seem to be issues you have expressed are.
1. What others think about you/ Approval of others.
2. Your self image. And feeling comfortable in your own skin.
3. Feeling uncomfortable talking to people.
Do you have anxiety talking to women and fear being rejected?
That's a good start! And the good news is there are things you can do to change them. And there's info out there on each of those. Good books you can read. Keep thinking about this and you will likely realize more.
From my experience. You can't make or force anyone else to approve of you. Trying to stop PMO to get acceptance isn't something I've felt is possible because eventually no matter what, you will feel someone isn't approving of you at some point and you are going to then think it's not working and then relapses happen. To me the most important thing is focus on approving of yourself first.
You might not be able to control your hair thickness. But there are things that you can do. Work on lifting weights, eating healthy, taking care of your mental health. Like you've said that may affect you in a positive way.
You can't just instantly change yourself but feeling comfortable talking to people is a skill that can be improved on. I remember being younger and being absolutely terrified of giving a speech in front of my peers. Since then though I've been a college coach where I gave presentations and coached in front of hundreds of people many much older than me and it wasn't something I worried about at all. The key here is to slowly learn to "stretch" my comfort zone by putting myself in situations where I wasn't comfortable. It's not always easy. But in time you can develop your ability to communicate with people.
There's one thing that you probably realize that is holding all this back though from changing. And I'm sure you know this is an issue. PMOing multiple times a day and choosing that over heathy behaviors will keep you from improving in these areas.
