I buzz my hair, I've been to two hairdressers here in Singapore and both times they've been unable to buzz it properly. First one, their clippers were a relic from the war era and kept cutting out, she then used beard trimmers and a comb to finally give me an uneven cut. The second one, I asked for a 2 cut, so she gave me a 2 on the top, and 1 on the sides, so of course I asked her to make it 1 all over, she was surprised I didn't want what I didn't ask for!
But, having said all that, I tell a lie, I've been to three hairdressers here. The third occasion was when I went to get a trim (when I had longer hair) back in December last year, it was in Chinatown, and she did an awesome job.
Actually, if someone can recommend a place that does good, cheap buzz cuts, please let me know. Even better if they use Wahl clippers.
