The most consistent advice I've seen regarding skin itching comes from Ginagirl. She recommends borax, Lugol's, coconut oil, and a few drops of an essential oil. The borax can be mixed with water and sprayed -- in the case of shoulders, I'd wet my fingers with the solution and let it dry on the skin. The itch relief is palpable. Lugol's helps heal the skin, and coconut oil protects, nourishes, and moisturizes. You can mix those two with the essential oil together, or layer them on separately. The Lugol's could go in with the borax and water. So many ways to personalize it. But those are the main products that I remember her having success with.
