Can intense regular work out help prevent hair loss?

Hi all!

I have been experiencing fluctuating hair loss since puberty.
Im 23 now.

However, ive been working out(all natural, no supplements) for the past 3 years. What ive noticed is, that when ever i work out regularly, and sweat thoroughly in the scalp, my hair tend to grow healthier. and hair loss decreases.

I keep my hair short, around 1.5 inch long.
