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.
Moreover, you can apply a paste of neem leaves as well. The honey and cinnamon paste works as a good home remedy for acne, even on the scalp, when applied for 15-20 minutes.
