Domenic the Gentleman's Hairdresser in Cambridge

Poor taste in designing a hairstyle. I had the most terrible nerdy hair I've ever had.
I told the hairdresser to push up "a little bit" at the back of my head. Yet, he made it quite short and flat, which is extremely unsuitable for someone with a flat head at the back (simply emphasizing how flat my head is). Besides, I also made a request that I hope my hair will not spike up when waking up in the morning. Before visiting this barber's, I only had this problem at one place of my head. Now it becomes worse, and I have two suffering this problem.
The hairdresser does not really care about their customer's requests and insist on doing whatever he wants even if it's a terrible idea. It is definitely unprofessional for a hairdresser not to notice how his customer's head is shaped and give a proper hairstyle based on it. I strongly suggest that anyone who'd like a decent haircut should not visit this barbershop.
