The two-Higgs-doublet model is one of the most studied BSM models.
The famous four types in the normal and inverted Higgs scenarios have different
still-allowed parameter spaces, which satisfy the theoretical requirements and the
experimental constraints at the electroweak scale. The high energy scale behavior
through the renormalization group equation analysis yields the cutoff scale of the
model. We will present the high-scale impact on the model parameters as well as a
new way to disentangle the high and low cutoff scales.
