My hair and scalp like stretching washes best. My scalp gets red and itchy if I wash too often or use sulphates. Other people like more frequent washes and/harsh shampoos because their scalp gets mad if they stretch washes.
I'd give stretching a go if I were you, since there is really only one way to see if it works for you! Plus less wet hair to deal with in the winter is always a win in my book.
