Isn’t adulthood just us looking at old photos, missing that effortless hair and wondering when it stopped being that easy?
Though multiple factors drive hair loss, one of the most overlooked is protein deficiency.
Nearly 80% of each hair strand is composed of protein called keratin
Low protein intake impairs keratin formation, causing thin, fragile hair that breaks easily.
It disrupts the growth cycle, pushing more hair into premature shedding phase (telogen effluvium).
Even after fixing protein intake, recovery lags. Hair grows ~0.5 inch/month, so visible improvement takes 3–6 months.
The focus should be on consuming 1.8g/kg of protein from good sources i.e. whole foods like eggs or legumes.
No supplement, serum, or shampoo can compensate for nutritional deficiency.
