Well I think they are not done just by looking at the bud. I've been growing for a long time and I can kind of tell from experience. Your buds just don't look very mature to me. If you can take a good pic of your bud and zoom in you should be able to see the trichomes better.
You do not go by hairs for harvest. You go by the color of the trichomes ( crystal) on the buds themselves.
Clear trichomes = not ready to harvest low THC levels
All cloudy trichomes= the highest level of THC your plant can produce. Some people would start to flush at this stage.
