learn Vitamin C
- Can low Vitamin C levels affect hair strength or thickness? Severe vitamin C deficiency (scurvy) changes hair, causing corkscrew hairs. There is no good evidence that mildly low levels thin hair.
- Is an itchy scalp linked to vitamin C? There is no evidence that an itchy scalp signals vitamin C deficiency, or that vitamin C treats patchy hair loss (alopecia areata). Patchy hair loss needs a doctor's diagnosis.
- Why is Vitamin C important for hair and hair follicles? Vitamin C is needed for collagen synthesis, antioxidant defense and iron absorption, all of which matter for hair follicles. Extra vitamin C has not been shown to improve hair in people who are not deficient.
