TLDR Fair skin, not red hair, affects health due to possible vitamin D deficiency.

The study explored the relationship between skin fairness, hair redness, and health outcomes, suggesting that skin fairness, rather than hair redness, was linked to impaired physical and mental health in individuals with red hair. The researchers proposed that vitamin D deficiency might play a role in these health issues, as fair-skinned individuals are more prone to vitamin D deficiency due to reduced sun exposure. The study was supported by Charles University Research Centre and the Czech Science Foundation.
