Thank you for viewing! This is a shampoo specifically for wigs, hairpieces, and toupees. It cleanses sebum and dirt from wigs. I've only used it once, and as you can see in the photos, it's almost full♪ When shipping, I will carefully wrap the cap with easy-to-remove masking tape to prevent any liquid from spilling. *Shipping is planned via Takkyubin Compact. ~How to Shampoo~ Pour the wig and about one capful of shampoo into a washbasin, add water, and lather. (The water will naturally create bubbles.) Soak for about 5-10 minutes, and when the dirt comes off, rinse with water. *Please refrain from scrubbing, as this can damage the wig. Towel dry, and the shampooing is complete(^^) Dry the wig in a place away from direct sunlight to finish. Please feel free to message me if you have any questions. Thank you! (^-^) No stains, tears, or odors...
