"The newest (and maybe strangest) way to strengthen damaged hair: applying a protein that's normally found in the lens of the eye. Scientists figured that crystallin, which helps form a protective coating in the eyes, might bind well to hair. When they engineered it in the laboratory and applied it to weak, overbleached hair samples, strand strength increased. In fact, \\\"we were able not only to make damaged hair recover but also to make it stronger than virgin hair,\\\" says Artur Cavaco-Paulo, a research professor at the University of Minho in Braga, Portugal. A company would have to mass-produce the protein for use in products, but the research may lead to the discovery of similar hair-repair agents, he says.\\n\\n#### See Also\\n\\n- [8 Products That Help Repair Damaged Hair](http://www.allure.com/beauty-products/hair/2013/hair-products-to-repair-damaged-hair)\\n\\n\\n- [How to Avoid the Biggest&amp;mdash;and Most Surprising&amp;mdash;Hair Mistakes](http://www.allure.com/beauty-trends/blogs/daily-beauty-reporter/2013/01/how-to-avoid-common-hair-damage-mistakes.html)\\n\\n\\n- [Hair Strengtheners](http://www.allure.com/beauty-trends/health/2013/nonprescription-pill-may-cure-thinning-hair)"^^<http://www.w3.org/2001/XMLSchema#string>
