To study the effects of addition of a redox metal, copper, antioxidants and metal chelators on the formation of free radicals in natural white Caucasian hair subsequently exposed to UV light. Three different methods, electron paramagnetic resonance (EPR), a fluorescent probe for hydroxyl radical formation (terephthalate) and free radical photoyellowing, were used. These methods utilized different UV sources and reaction conditions, and so can give insights into the different mechanisms of action occurring during UV oxidation of hair. In addition, this study demonstrates how antioxidants and chelators can be screened to determine whether they can protect hair from UV damage.

紫外线对头发的伤害以及抗氧化剂和金属螯合剂的影响。

研究添加氧化还原金属、铜、抗氧化剂和金属螯合剂对随后暴露在紫外线下的自然白色高加索头发中自由基形成的影响。使用了三种不同的方法，电子顺磁共振 (EPR)、用于羟基自由基形成（对苯二甲酸酯）的荧光探针和自由基光变黄。这些方法利用了不同的紫外线源和反应条件，因此可以深入了解头发紫外线氧化过程中发生的不同作用机制。此外，这项研究展示了如何筛选抗氧化剂和螯合剂以确定它们是否可以保护头发免受紫外线伤害。
