Seng untuk Alopecia Areata
FBerdasarkan 46 studi (3 meta-analyses, 1 RCT) dengan 23,495 peserta secara total. Hasil bervariasi di antara studi-studi tersebut.
Kesimpulan
While people with alopecia areata often have lower zinc levels, research is mixed on whether zinc supplementation helps — it may support overall immune health but is not a reliable solution for alopecia areata.
- Lower zinc levels are consistently found in alopecia areata patients
- Supplementation studies show inconsistent results for hair regrowth
- Zinc plays a role in immune function, which is relevant to autoimmune hair loss
- No large-scale RCT specifically tests zinc supplementation for alopecia areata
