Nailing Down Nail Conditions

Dr. Zain, Heather, and Courtney break down why nails matter in dermatology, covering basic nail anatomy, slow toenail growth, and how trauma can change nails. They review common nail findings (ridges, Beau’s lines, pitting, thickened nails, habit-tic damage), brittle/splitting nails, and color changes including yellowing, white spots, green nail (Pseudomonas), and brown streaks (melanonychia) with red flags for melanoma and when biopsy may be needed. The episode also covers nail infections (fungal, bacterial paronychia, HPV warts), treatment options and timelines, nail salon safety (tool cleaning, UV lamp sunscreen, avoiding over-trimming cuticles), common myths, and when to see a dermatologist—especially for new or changing pigment or symptoms like pain, bleeding, or lifting.00:00 Gross Toenail Talk: Socks Off = Crime Scene00:55 Welcome to Skin Side Out: Why Dermatologists Care About Nails02:10 Nail 101: Anatomy, Matrix Biopsies & Why Nails Change Slowly03:18 Growth Rates & Trauma Clues (Toenails Take Forever)04:34 Texture Changes: Ridges, Beau’s Lines, Pitting & Inflammation08:34 Thick, Curved “Ram’s Horn” Nails vs Fungus Myths09:34 Habit-Tic Deformity: Nail Picking, Biting & Permanent Damage12:52 Brittle & Splitting Nails: Onycholysis, Peeling, Lichen Planus + Causes15:06 Supplements & Medical Causes: Water, Acetone, Thyroid + Biotin16:40 Nail Color Changes: Yellow, White Spots & When to Worry17:48 Brown Streaks (Melanonychia) vs Bruising: Hutchinson Sign & Biopsy Decisions21:19 Green Nail Syndrome: Pseudomonas from Nail Enhancements22:07 Green Nail Syndrome & Where Pseudomonas Hides23:09 Fungal Toenail Infections: Causes, Contagion & Why OTC Fails24:39 Treating Nail Fungus: Orals, Rx Topicals, Home Remedies & Lasers26:12 When Fungus Gets Gross: Thick Nails, Spreading & Podiatry Help28:17 Bacterial Nail Infections: Paronychia, Triggers & Painful Drainage30:07 Viral Nail Problems: HPV Warts Around (and Under) the Nail31:39 Nail Salon Safety 101: Tools, UV Lamps, Breaks & Cuticle Care35:29 Rapid-Fire Nail Myths (Biotin, “Breathing,” White Spots & More)37:53 When to See a Dermatologist + Final Nail Care Tips
