  AdS/CFT correspondence is a "first-principle" tool to study the strongly
coupled many-body systems. While it has been extensively applied to investigate
the continuous symmetry breaking dynamics, the discrete symmetry breaking
dynamics are rarely investigated. In this paper, the model of kink formation in
a strongly coupled one-dimensional chain is realized from the AdS/CFT
correspondence. In doing so, we first construct a model of real scalar fields
with parity symmetries in the AdS bulk. By quenching the system across the
critical point at a finite rate, kink hairs turn out in the bulk due to the
spontaneous parity symmetry breaking, which accomplishes a counter-example of
"no hair conjecture" of black hole. Due to the AdS/CFT correspondence, kink
hairs in the bulk are dual to the kinks in the AdS boundary. The mean of the
dual kink numbers are found to satisfy a universal power-law relation to the
quench rate, in agreement with the celebrated Kibble-Zurek mechanism. Moreover,
the higher cumulants of the kink numbers are proportional to the mean numbers,
consistent with the assumption that the formation of kinks satisfy the binomial
distributions which goes beyond the Kibble-Zurek mechanism.
