Bad Color Choices
It should be common sense, but some people still do not consider their skin tone when picking a hair color. You should stick to cool hues if your hair comes with cool undertones. On the other hand, you should go for warm hair colors if you have a warm complexion. There are exceptions to the rule, of course. At any rate, you should learn from the mistake that Beyonce made a while back.
Dreadlocks
You should probably get rid of your dreads unless you are indigenous African or Jamaican. They should no longer be trends in 2020. If you do not want unwanted attention, it is a good idea to pick a different hairstyle. On top of that, they are actually quite uncomfortable. They will be unhygienic unless you take good care of them as well.
