The most frequently asked question about washing wigs is How Often Should I Wash My Lace Wig?
The answer is, it depends on how often you wear it and what type of damage it incurs while wearing.
If you wear your wig every day and use styling products, you should wash it at least once a week. Or, it only needs to be washed once every 5 to 10 wears.
Wigs do not need to be washed as often as your own hair, because too much washing does harm to your wig, but too less washing will cause hair tangling.
