What are the best measures to be taken to improve hair thickness?

To improve hair thickness, consider incorporating a balanced diet rich in protein, vitamins (especially biotin and vitamin E), and minerals like zinc and iron, as these nutrients promote hair health. Regular scalp massages can enhance blood circulation, stimulating hair follicles. Additionally, avoid excessive heat styling and harsh chemical treatments, opting for gentle hair care products instead. Supplements, such as biotin or collagen, may also support hair thickness, but it's best to consult a healthcare professional before starting any new regimen.
