The system has multiple servers (the three hairdressers), so the first letter is M for Markovian or Memoryless. 
The second letter is M because customer interarrival time follows the Poisson distribution. 
The third letter is 3 because there are three servers (hairdressers).
The service time follows the exponential distribution, which is considered Markovian or Memoryless, so the last letter is also M. Therefore, the Kendall notation for this system is M/M/3.
