Emerging national attention to problems of aging in the mid-to-late 1970s stimulated research to better define zinc status and requirements of the older population. The commercial exploitation of hair analysis as a way to diagnose trace element deficiencies is unfortunate. Although hair zinc levels have been useful in comparing zinc status of population groups, usefulness of this technique with respect to assessment of the individual is extremely limited.
20世纪70年代中后期，全国开始关注老龄化问题，这刺激了相关研究，以更好地界定老年人的锌状况和需求。将头发分析作为诊断微量元素缺乏症的一种方法进行商业开发是很不幸的。虽然头发中的锌含量有助于比较不同人群的锌状况，但这项技术在评估个体方面的作用极为有限。
