Summary: ``The results of this paper are the extension of Kumar et. al (2021) by introducing a new category of unicyclic graphs which we call {\it extended hairy cycle}. If one of the leaves of a path is joined to each vertex of the cycle by an edge, the resulting graph is called {\it extended hairy cycle}. We prove that all extended hairy cycles on cycle of length multiple of four possess an alpha labeling. Furthermore, we also establish the graphs obtained from the same have alpha labeling. We also find the missing numbers for each case.''
