Quick Answer
Five physician steps if your brows are thinning: (1) rule out medical causes — thyroid, iron deficiency, alopecia areata — with a basic lab workup; (2) stop aggressive plucking, waxing, threading; (3) apply a peptide-led brow conditioner nightly — MD Eyebrow Conditioner™; (4) support inside-out nutrition (biotin, iron, vitamin D, marine collagen); (5) give it 3-6 months.
