  The soft-wall model, emerging as bottom-up holographic scenario anchored in
the AdS/CFT correspondence, displays the disappearance of normalisable modes
referring to vector mesons at a temperature $T_{\dis}$ depending on the
chemical potential $\mu$, $T_{\dis}(\mu)$. We explore options for making
$T_{\dis}(\mu)$ consistent with the freeze-out curve $T_{\rm f.o.}(\mu)$ from
relativistic heavy-ion collisions and the cross-over curve $T_{\rm c}(\mu)$
from QCD at small values of $\mu$.
