The no-hair conjecture in General Relativity (GR) states that a Kerr black\nhole (BH) is completely described by its mass and spin. As a consequence, the\ncomplex quasi-normal-mode (QNM) frequencies of a binary-black-hole (BBH)\nringdown can be uniquely determined by the mass and spin of the remnant object.\nConversely, measurement of the QNM frequencies could be an independent test of\nthe no-hair conjecture. This paper extends to spinning BHs earlier work that\nproposed to test the no-hair conjecture by measuring the complex QNM\nfrequencies of a BBH ringdown using parameterized inspiral-merger-ringdown\nwaveforms in the effective-one-body formalism, thereby taking full advantage of\nthe entire signal power and removing dependency on the predicted or estimated\nstart time of the ringdown. Our method was used to analyze the properties of\nthe merger remnants for BBHs observed by LIGO-Virgo in the first half of their\nthird observing (O3a) run. After testing our method with GR and non-GR\nsynthetic-signal injections in Gaussian noise, we analyze, for the first time,\ntwo BBHs from the first (O1) and second (O2) LIGO-Virgo observing runs, and two\nadditional BBHs from the O3a run. We then provide joint constraints with\npublished results from the O3a run. In the most agnostic and conservative\nscenario where we combine the information from different events using a\nhierarchical approach, we obtain, at $90\\%$ credibility, that the fractional\ndeviations in the frequency (damping time) of the dominant QNM are $\\delta\nf_{220}=0.03^{+0.10}_{-0.09}$ ($\\delta \\tau_{220}=0.10^{+0.44}_{-0.39}$),\nrespectively, an improvement of a factor of $\\sim 4$ ($\\sim 2$) over the\nresults obtained with our model in the LIGO-Virgo publication. The single-event\nmost-stringent constraint to date continues to be GW150914 for which we obtain\n$\\delta f_{220}=0.05^{+0.11}_{-0.07}$ and $\\delta\n\\tau_{220}=0.07^{+0.26}_{-0.23}$.\n
