A triad would only provide you with three wires/conductors/cores, and a properly-applied 4-wire RTD requires 4 (four) wires/conductors/cores. You could use two (2) two-wire (conductors; cores) twisted, shielded pair cables for a total of four wires/conductors/cores--which is what should be used for a 4-wire RTD.
The solution for crusty scalp is to purify the root and scalp and help to ph balance the skin on the scalp. This allows the natural zinc barrier in the scalp to act as it should to ward off any bacteria.
Another home remedy for scalp sores is mixing a small amount of apple cider vinegar with some warm water and applying the mixture directly to the sores. You may find this helps control flakiness and itch as well. Be sure to rinse well after treatment. Oatmeal is also great for dry skin and sores on the scalp. You may find this in an oatmeal-based shampoo or you can make your own oatmeal paste yourself. If you wish, mix in a teaspoon of natural tea tree oil for added relief. Alternately, you might try an all-natural oatmeal soap.
