Off-kilter hormones can affect the thickness of your hair. In fact, women with thyroid imbalances, new mothers, and menopausal women in particular may experience hair loss due to a drop in levels of estrogen.
“Optimal levels of estrogen help to grow full thick hair while low estrogen levels lead to thin and stalled hair growth, which eventually leads to hair loss,” says Kristin Dahl, a Los Angeles–based nutritionist and women’s wellness educator. “Estrogen is secreted through the ovaries and adrenal glands, however, as the adrenals are typically overburdened due to stress, symptoms of menopauses like hair loss and hot flashes occur prematurely and excessively for some.”
So while some things are out of your control (with or without medication), there are ways to help lower your stress hormone production and keep your hair healthier, shinier, and therefore thicker. Consult your doctor about supplements with adaptogenic herbs, like Ashwagandha root and leaf extract, and amino acids to support keratin productions.
