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!

If my diet lacked iron, protein, nutrients from poor eating for more than 3 YEARS consistently, can that contribute to hair loss? Example- literally never eating iron (I'm vegetarian) and maybe 20 grams of protein on an average day if that?

Derm said I have TE. Over the past few months, I upped protein/iron intake (they were low) with healthy, balanced diet. Past couple days, hair loss increased a bit. Could my new eating be working and this is new hair growth pushing current hairs out?
