24M, is it a false alarm, or is it natural for thin hair to be like this in direct light ? Please help

No male pattern baldness in family probably, my dad has thin but full hair, so did my grandpa. I eat eggs 3-4 days a week. I do have poor sleep cycle though. Experienced hairfall in Nov-Jan due to dandruff. Then I began using 2%Keto twice a week. And weekly (sundays) massage with Rogan-badaam + castor oil. Ketoconzole made my hair really dry so I used a conditioner. Still I would get 2-3 strands each time I ran my hand through.

Hairfall has stopped now. But I am worried about these thin patches. I have two whorls at the back of head and that makes it even worse
