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.
1 Rinsing your scalp with a rinse of 1/4 cup white vinegar to 3/4 cup water may help the problem. 2  The natural acids will help loosen any sebum (dead skin and oils) that clings to your scalp and flakes to form dandruff. 3  Rinse thoroughly with warm, not hot, water. 4  If you don't rinse well, you will smell like vinegar.
