Why Your Hair Loss Doctor Never Tests This (But Should)
from Fuel Different · host Sarah Williams
Your hair is falling out, but your iron levels look "normal" on paper. Sound familiar? In this episode, Sarah Williams reveals why 72% of women with unexplained hair loss are walking around with a hidden iron deficiency that standard blood tests completely miss. 🎯 What You'll Learn: • Why ferritin levels below 70 ng/mL sabotage hair growth (even when labs call it "normal") • The 1,000mg iron storage rule most doctors don't know about • How mild iron deficiency tricks your hair follicles into early retirement • Which specific test to request when your doctor says your iron is "fine" 👤 Perfect for: anyone dealing with unexplained hair loss who's been told their blood work looks normal but still watching their hair thin out. 📍 Chapters: [00:00] Sarah Williams breaks down the ferritin blind spot [02:15] The 72% statistic your doctor probably doesn't know [04:30] Why "normal" iron isn't enough for healthy hair [06:45] The 1,000mg rule that changes everything [08:30] Real lab ranges vs. optimal hair growth numbers [10:15] How to get the right test ordered Most doctors test for anemia, not hair loss. There's a difference, and it matters way more than you think. If you've been told your levels are fine while your hairbrush tells a different story, this episode connects the dots between what your lab results say and what your hair actually needs. Sarah breaks down the research showing how iron deficiency can shift hair from growing phase to resting phase, creating diffuse thinning that creeps up slowly. You'll walk away knowing exactly which numbers to look for and how to advocate for the right testing. 🔔 Never miss an episode: Follow Fuel Different on Spotify or Apple Podcasts and turn on notifications.
