Male pattern baldness?

[Myaccount]

In the last 3 months I have noticed thinning on my crown with an itchy scalp in that area with hair loss in the 50 - 100 hairs per day range. During the time it started my diet was very bad (i was in a calorie deficit to lose weight which in which i lost 6kg in around 2.5 weeks). I was under a large amount of stress at the time aswell. To this day i still notice thinning in my crown, itchy scalp and hair shedding.
Do you think this is MPB or stress given that my dad started losing his hair around my age but lost it from the front whereas my hairline is intact at a strong norwood 2 which ive had for many years. Thanks in advance
