Q. In Question 1821 you write that Rav Miller permits permanently removing hair of the ear since it is usually done for remedy or curative reasons. Does this apply to hair growing on the exterior section of the ear as well or only on the inside of the ear
A. Horav Shlomo Miller's Shlit'a opinion is that it is also permitted. Although it may be considered basically an aesthetic procedure, since it is unusual, embarrasing and unpleasant. It is similar to the opinion of Nishmas Avrohom (Y.D. 182 p. 140) quoting Horav S.Z. Auerbach Zt”l that permits the removal of embarrassing excessive hair between the eyebrows, (question 1429). In this case even plucking would be permitted if it is the way it is permanently removed. The same may apply to the removal of hair growing out from one's nose.
