Does Lack Of B12 Cause Scurf In Your Hair?

I asked Google AI this question and received this answer.

Yes, a deficiency in Vitamin B12 can contribute to poor scalp and hair health, which may manifest as scurf (dandruff/dry skin flakes) or dry, brittle hair.

While B12 is best known for its role in preventing hair loss and thinning, it plays a critical role in maintaining scalp moisture and health.

Here is how a lack of B12 can affect your hair and scalp:

Dryness and Flaking (Scurf): A deficiency can cause your hair and scalp to become dry, brittle, and flaky.

Hair Shedding: A lack of B12 can cause diffuse hair shedding or thinning, particularly because hair follicles are starved of nutrients when red blood cell production is impaired.

Premature Graying: Low B12 levels are also linked to premature whitening or graying of hair

I’ve certainly suffered from scurf at periods in my life.
