The document is a report comparing two hair salon businesses - Stella, a home-based salon in Banting, and Tenze Hair Studio, a commercial salon with 6 branches. Stella was founded in 1989 and started as a shop called Leaves before the owner, Stella Lim, took over and renamed it. Tenze was founded in 2002 by Avier Ng and has expanded steadily over the years. Both salons face competition from other local salons. While Stella focuses on loyal customers through good service, Tenze differentiates itself through fashion show work and new monthly packages. As monopolistically competitive firms, they have weak pricing power and must compete intensely on product differentiation.
