Thin hair, but no hair loss

[Androsclerosis]

I'm 22, 82 kg, I noticed that the head hair have thinned, but I have no hair loss. Everytime I run my hand through my hair I got just 1-3 hairs.
My brother eats lots of pufa, he is a bit overweight and tired and he does not have this issue. Neither my father.

My genetics are great regarding hair. I can easily grow a big beard.

My diet:
Fat - Low pufa, mostly saturated, butter from Ireland
High carb, medium protein, low fat - orange juice, ground beef, rice, mushrooms, milk, bananas
Daily calories around 2000-2500
High salt intake
No more than 20 g cane sugar/day

I walk everyday a lot
Body temperature 36.5 C
Pulse 65-75.
Progesterone and androsterone almost daily, not combined

I have poor quality sleep due to sleep apnea and overproduction of mucus. I strongly believe it's an allergic reaction.

What do you think is the cause of thinned hair?

Progesterone and high dose caffeine, also high nutrient diet.

Most probably yes.. Progesterone and high nutritious diet, like liver weekly, whole milk and low fiber diet will help. I started randomly last week this kind of diet and my hair became more glowy.
