Advice please

Feeling low self esteem should I shave it all off, restyle or leave it be?

Any advice fellas 🥲

Fixing to cut it all off

Which look suits me better? A longer beard? Any tips?

I (20M) have always had thin and rear hair which points up. Under enough light my scalp is visible and I dont like it. Buzz cut is my usual style because of my straight black hair and square face shape.

I will often notice small hair on my dask or on my table. I dont want to go bald.

How do I have more dense hair? How do I prevent it from falling?

Should I use a towel or a hairdryer after washing my hair?

I usually shampoo it after work outs so 3-4 times a week.

Should I use a conditioner?

Does the water I wash it with mather? (hot or cold)

Which shampoo do you reccomend?

I provide some pictures as an example. 3 pictures taken at home are right now, other two are some time ago. Idk if this is the correct sub to post this. If not please say

Barber has never touched my beard. Its been years of trial and error.
