If i mixed together equal portions of anti-itching shampoo, moisturising shampoo and conditioner..?

I read where vinegar will treat dandruff I use tea tree oil shampoo and avoid stress as that can bring on dandruff or maybe your mane has been in the sun too much causing the dryness, dunno look up herbal treatments for it because that might be lemon juice and rosemary too or both or some and neither of one of those.
