I'm not familiar with how to use it, so I may not be able to answer depending on the content of your questions. Thank you for your understanding. The partial wig is light gray. *I believe there is no particular damage, but please forgive any oversight. *The shampoo and conditioner are likely about 90% full, but I can't tell from the appearance, so please consider this as a reference only. We cannot accept returns based on the actual remaining amount, so please be aware of this.
