If hair loss showed huge decrease and also regrowth after increasing iron/protein in diet for a few months, could that mean there was a deficiency?

Yes it could!: A study in the Journal of Korean Medical Science found that iron deficiency may play a role in hair loss, especially in premenopausal women with female pattern hair loss. Protein deficiency may cause hair loss, according to a Harvard study. To prevent hair loss, you need 0.36 g protein per pound of body wt. See your Dr and have your iron levels checked. Too much or too little iron is unhealthy!
