Small patch:

• Fixed bug where integrity related traits were not working properly
• Added three new traits allowing you to change your hair color
• Mr. White will allow you to reset your traits and pick them again
• Items that affect values like mood or wellness now show your current value in sale and inventory windows

To change your traits mid-game, find Mr. White and talk to him. Select the "services" option while you have ancient power source in your inventory. This will reset your traits and allow you to pick new ones. Stat bonuses will not reset so you can use this to get stronger faster. 

This is only temporary solution. I will add proper way to reset your traits much later.
