Get the Long Hair look
Keep it long and straight, but don't go for ion straightening as it will appear unnatural. If you have short hair, you can try a wig. Make sure it's parted in the middle. You can find $200 wigs on Pottinger Street.
Long Hair only wears Che Guevara T-shirts. These can be found in Mongkok's Ladies Street. To complete the look, wear scruffy trousers and cheap sandals.
As a professional protester, Long Hair always has DIY props with him: coffin, national flag, SAR flag and even the Basic Law. He always carries a lighter or matches in case he needs to burn these props in front of the Central Government Offices.
Long Hair is very well-read and a Trotskyite. Read books on Che Guevara and Marxism. Make sure you catch the movie The Motorcycle Diaries based on the book by Guevara. It will be shown at the end of next month.
