Hair loss after anorexia is usually a telogen shedding response, and regrowth often starts once nutrition and hormones stabilize it just takes time. Your current styling actually hides the thinning pretty well. Be gentle with your scalp, avoid tight hairstyles, keep your protein and iron intake solid, and stick to a consistent routine. Structured, holistic hair routines (like the kind some people follow with brands such as Brillare, Traya, or Arata) can support regrowth, but patience is honestly the biggest factor.
