There's no single answer because 'hair loss' isn't one thing. Step one is to figure out which kind you have. If it's gradual thinning at the crown or hairline (pattern loss), the proven, evidence-backed treatments are topical minoxidil and, for men, oral finasteride — and they work best started early, before follicles are lost. If it's sudden diffuse shedding (telogen effluvium), the answer is to address the trigger: stress, a crash diet, low iron (ferritin), or thyroid problems.
Red flags — sudden round patches, sores or scaling, scarring, or rapid loss — mean see a dermatologist promptly rather than self-treating. Skip the unproven stuff (most serums, supplements unless deficient, 'detox' routines); it wastes the time that matters. Use a 90-second self-check to find your type and the right next step, then act early.

FAQ
What's the single best thing to stop hair loss?
For genetic pattern loss, starting a proven treatment (minoxidil, and finasteride for men) early is the highest-impact move. For temporary shedding, removing the trigger and fixing nutrition is. Match the action to the cause.
Can I stop hair loss naturally?
You can reverse temporary shedding by fixing deficiencies and triggers (iron, protein, stress). But there's no natural cure for genetic pattern loss — proven medical treatments are what actually slow and partly reverse it.
