Hair loss

Ya

I have had heavy periods all my life and my iron tends to drop every time I get my period. I have been anemic before because of it (and bad eating habits) and have been through an awful phase of extreme hair loss. My head would shed in clumps daily and it was devastating. I had to cut my hair very short and it made me feel so ugly. I am currently recovering and my hair has been growing a lot. Out of the blue I noticed I am shedding again and I don’t know what to do?? I am eating very healthy and exercise 5 times a week. Any advice someone could give me?
