Most hair shedding is the body waving a flag, about iron, thyroid, stress, or protein. Here's the beginner version of what actually helps.
Here's the key idea: supplements help hair mainly when they correct a real deficiency. If your levels are already fine, more won't grow extra hair. So the smartest first step is usually a blood test, not a bottle.
Iron stored in your body, measured as "ferritin."
Low ferritin is one of the most common causes of shedding, especially in women with heavy periods. Only supplement if a test confirms it.
The "sunshine" vitamin involved in the hair-growth cycle.
Deficiency is linked to more shedding. Common and easy to test.
A mineral needed for hair tissue growth and repair.
A genuine deficiency can cause hair loss, correcting it helps.
Hair is mostly protein (keratin).
Crash diets and very low protein intake can trigger shedding. Eat enough first.
The famous "hair vitamin", but true deficiency is rare.
It only helps if you're actually low. For most people it does little. And it carries an important safety catch (right).
We read your labs to find the real cause, screen every suggestion against your medicines, and grade everything honestly by evidence.
