First, it's good that you've identified this early on. Are you on finasteride and minoxidil?
So who might I take after? What's the possibilty that I will be balder than them? Why did it start this early for me?
Hair loss is unpredictable since it's multifactorial and different males within a family can have it at different onset in terms of age. There's a term in genetics called penetrance and that can help explain why someone may have MPB earlier on than their father. Beyond genetics, there are issues with stress, hormones (like cortisol), neurotransmitters, TSH, etc.
I would consult with your physician and get a TSH and cortisol checked. Ask your doctor about finasteride and minoxidil as well. As always, feel free to ask me questions and you're welcome to private message me as well.
