<p>Rav Yitzchak Isaac of Kormana said that Rav Chaika of Amdur’s Yiras Shomayim was so great that all his hair fell out, leaving him bald ! He also said this in the name of Rav Herschel of Zidachov, who used this concept to illustrate a pasuk in Parshas Tazria (Vayikra 13:40): “If the hair of a man’s head falls out, he is bald and pure”. If all of a man’s hair falls out because he fears Hashem, he is surely pure, because this is indeed a lofty level, just like Rav Chaikel of Amdur!” (Nesiv Mitzvosecha, Nesiv Emuna, Heichal HaBerocha, Ki Sisa)</p>
