    TLDR Kids with alopecia areata had lower vitamin D levels than healthy kids.
    In 2019, a case-control study was conducted on 30 pediatric patients with alopecia areata and 30 healthy controls. The study found that the mean serum Vitamin D level in the alopecia areata cases was significantly lower than that of the controls (17.21 ± 6.57 ng/ml vs. 25.03 ± 13.84 ng/ml; P < 0.05). Additionally, 73% of the alopecia areata patients had Vitamin D deficiency compared to 46% in the control group. There was a significant inverse correlation between the Severity of Alopecia Tool (SALT) scores and serum Vitamin D levels in the alopecia areata patients (r = -0.379; P < 0.05). This suggested that Vitamin D deficiency may be involved in the development of alopecia areata and could be a useful marker for disease severity. Further studies were recommended to assess the potential benefits of Vitamin D supplementation in treating pediatric alopecia areata.

They are considering various treatments like spironolactone, estradiol, and possibly finasteride, while also exploring the possibility of hormonal imbalances or autoimmune issues.

      community Using topical vitamin D, does it make sense?

      Topical Calcipotriol (vitamin D derivative) may help with hair regrowth, especially for alopecia areata. The user wonders if adding classic vitamin D to lotions like Minoxidil could have a similar effect.
