Trying to portray vividness (may be weirdness) of my personality with vivid colors.

(1) Cut small pieces of two-sided tape and stick them under the pin heads.
(2) Trim the tape with small scissors so that tape does not extend beyond pin-head.
Because light will reflect off of those pieces and ruin the portrait.
(3) Trimming is easier/faster if you cut triangular pieces, not rectangular.
(4) Have someone stick those on your head. Having a good quality tape is very important.
(5) Do not forget to make it clear to your hairdresser, which side you want stick in your head.
Bribing the hairdresser with a nice-restaurant-dinner helps btw.
(6) IMP: Decide the angle of light to avoid pin-shadows.
(7) Steps 1-to-5 take more than an hour but it took me completely painless 10 seconds to get those off.

Note: Just offer a big warm smile to your neighbours if they happen to see you like this :)
Trust me, no explanation with words will work.
