How can I have black hair when I'm naked?

The method for obtain dark hair by exposure is as follows:

1. Go to Ye Yun through the second door, and then go to the ancestral stone tablet.

2. Click on the icon above the ancestor, find the hair icon, click and exchange with it.

There are two ancestors who can exchange hair in Ye Yun. Candles needed for exchanging hair can be obtained by collecting candles.
