It is frecuently an inherited thing related to testoterone levels.
I began to become bald since your age.

But alternatively, some other factors should be tested.
Stress, skin intolerance to shampoos (they are basically detersives), lack of some elements in your daily food, cholesterol.
Doctors may help if it´s not an inherited thing.

Have you looked up alopecia? My ex bf had a slight condition of it

That would be tough for a young guy to go through

That's in your genes. You inherited that from an ancestor.

Start the rogain regimen. Male pattern baldness was a gift from your mother . Women carry that gene.

We, bald ones, move the World!
