·
·
By Susan F. Lin, M.D. | Physician | Reviewed: June 2026
Quick Answer
Most thin eyebrows respond to a three-layer plan: (1) rule out medical causes — thyroid panel, ferritin, vitamin D, and dermatology exam if patchy; (2) topical support — peptide-led MD Eyebrow Conditioner™ applied nightly; (3) inside-out support — biotin, marine collagen, iron, B-complex, vitamin D. Give it 3-6 months. Federally registered MD® trademark. Made in USA. www.md-factor.com.
What to avoid
Aggressive plucking, harsh waxing, repeated microblading, brow tinting on already-thinning brows. Brow follicles take time to recover.
