结论
Moderate evidence suggests that omega-3 fatty acids may help support hair recovery in telogen effluvium, though the research base is limited and they are usually studied alongside other nutrients.
- 8 out of 11 studies show positive effects, but total sample size is small (317 participants)
- Often studied as part of multi-nutrient supplement formulations
- No large-scale RCTs specifically for omega-3 and telogen effluvium
- May support recovery through anti-inflammatory and nutritional mechanisms
