In an effort to take care of their skin, nails and overall health, many people often use daily supplements. However, these tablets are not completely harmless to hair. Some types can promote hair growth, but if overdose or not prescribed by a doctor, they can cause hair loss, thin hair or breakage.
According to Dr. Pravin Banodkar, MBBS, DNB, DD (UK), FIDP Dermatology, Co-founder and Dermatologist Skin beyond borders (Mumbai, India), vitamins and minerals dissolved in oils such as A, D, E and K accumulate in the body and can cause imbalances if overdose.

Excess vitamin A: Accelerates hair loss, making hair thin, spreading on the scalp.
Excess zinc: Causes exhaustion, weak collagen and hair follicles.
Excess selenium: Causes brittle, broken hair, and even scalp inflammation.
Combine many types of supplements: easily leading to dosage exceeding safety level, negatively affecting hair health.
Hair loss due to imbalance, not due to deficiency
