Yes, this is treatable. Perimenopausal hair thinning is mostly female pattern loss driven by falling estrogen, and it is very often made worse by low
ferritin, low
vitamin D and an underactive
thyroid - all three are common at 43. So before any tonic, get
TSH, CBC with ferritin, vitamin D and
B12 done. If those are normal, topical minoxidil 2% once or twice daily is the treatment with real evidence, along with adequate protein and iron. It takes 3-4 months to show, so don't judge it in weeks. Avoid random biotin combos and frequent chemical straightening. Share your reports with me on a Practo consult and I'll give you a definite regimen instead of guesswork.
