@nakatrichology: Before you reach for biotin gummies or hair growth oils, check what’s actually missing. Iron, zinc, vitamin D, niacin (B3), and biotin (B7) are scientifically proven to impact how your hair grows — but only if your levels are low. Low iron can slow oxygen flow to follicles. Low zinc can weaken new growth. Low vitamin D can interrupt the hair cycle. Too much of anything — even vitamins — can cause more shedding. If you’ve noticed consistent thinning or shedding, start with a blood test. That’s how you build from truth, not trial and error. 🧠 Evidence first. Always. #undrthedryr #healthyhair #trichology #haireducator
