Yes, You Can Deduct Wig Costs
Believe it or not, your wig costs are deductible under certain conditions.
If your hair loss is associated with chemotherapy or other cancer treatments, your wig is a deductible medical cost provided your doctor advised you to purchase it for mental health reasons. It's important to note, though, that you can only deduct medical expenses should they exceed 10 percent of your adjusted gross income (AGI), or 7.5 percent if you are over age 65.
Likewise, if you're an actor or performing artist who's an independent contractor and you need the wig for performance purposes, it may qualify as a business expense that can be deducted from income associated with performing.
