Agree with Fiona here, "good-looking" does not always equal "sexy"....
Never really been down to the skin because my head shape is a bit unco but since I came here I stopped bothering getting shaved hair cuts because the hair dressers don't know how to use clippers and use those crappy toy looking battery clippers instead of proper professional ones. They get the comb out and start shaving the hair poking through it so you end up with strands of hair sticking out all over the place. Have yet to convince one to put the number 2 attachment on and just dig in to make it even.
A good hair stylist/barber will compare the shade in colour as he shaves your head. Some will use a plain white background, others will put their back of their hand against your head to judge the shade in colour. Its not all about the same length all over, but the overall shade in colour, so you don't have light or dark patches. Properly done, it can take over 30mins.
Well said proplus
Go to a cheap barber here in HK and it shows.
