Alright...Let’s talk about hair loss without the fluff, the fear-mongering, or the $79 shampoo. 🧠🧬Hair is a biological receipt of what’s happening inside your body. When it starts thinning, shedding, or ghosting your scalp, something upstream is usually off. Here’s the science-backed breakdown you can actually use. 🧠 First: Hair loss is a signal, not a diagnosis Common patterns we see: • Diffuse shedding (stress, nutrients, hormones) • Thinning at temples/crown (often DHT-driven) • Patchy loss (autoimmune, alopecia areata) • Brittle, slow growth (thyroid, iron, protein, estrogen deficiency) Translation: the follicle is reacting, not misbehaving. 🧬 Nutrient deficiencies strongly linked to hair loss These show up over and over in labs: Iron / FerritinLow ferritin = hair follicles go into “energy conservation mode.” Target ferritin for hair regrowth is often >50–70 ng/mL, not “barely normal.” Food sources: 🥩 red meat 🦪 oysters 🌱 lentils + vitamin C pairing Protein Hair is literally keratin (a protein). Chronic under-eating = shedding. Food sources: 🍳 eggs 🐟 fish 🥩 poultry, beef 🧀 Greek yogurt Zinc Needed for follicle repair and growth signaling. Food sources: 🦪 oysters (again—hair MVP) 🥩 beef 🎃 pumpkin seeds Biotin & B-vitamins Important—but not magic alone. Low levels usually reflect gut or absorption issues, not diet alone. Food sources: 🥚 egg yolks 🥑 avocado 🌰 nuts & seeds Vitamin D Low D = follicles stuck in the “rest phase.” Food sources: ☀️ sunlight 🐟 fatty fish 🥚 egg yolks 🔄 DHT: the hairline assassin DHT (dihydrotestosterone) shrinks follicles in genetically susceptible people—especially at the temples and crown. What increases DHT conversion? • Insulin resistance • Chronic stress (cortisol upregulates 5-alpha reductase) • Low estrogen or progesterone balance • Poor liver detoxification Foods that may support healthier androgen balance: 🥦 cruciferous veggies (broccoli, cauliflower) 🫒 olive oil 🍵 green tea 🥬 leafy greens This is not about “blocking testosterone”—it’s about metabolic balance.
