Increased shedding, dry, splitting hair, slow growth after hair loss and brittle strands could be a sign of vitamin C deficiency. Including vitamin C-rich foods like peppers, citrus foods, broccoli, and strawberries can help restore vitamin C levels.
The "Big 3" for thinning hair, especially male/female pattern baldness, are typically Minoxidil (Rogaine), Finasteride (Propecia), and sometimes Ketoconazole shampoo, or even Microneedling, forming a multimodal approach to stimulate growth and block hormones (DHT) causing hair loss, with Minoxidil boosting circulation, Finasteride inhibiting DHT, and Ketoconazole reducing inflammation and acting as a mild anti-androgen.

Key vitamin deficiencies linked to hair loss include Vitamin D, B12, Biotin (B7), and Iron, with low levels of these nutrients affecting hair follicle function, protein production (like keratin), and oxygen supply, leading to thinning or shedding; however, excessive intake of some vitamins (like A or selenium) can also cause hair loss, so a doctor should confirm deficiencies via blood tests before supplementing.
When deficiency disrupts vitamin D in your scalp, the anagen (growth) phase shortens. This prematurely pushes more resting follicles into the telogen (rest) phase. Excessive shedding occurs, resulting in thinner hair.
