How-to Q&A

To effectively wear a wig, start to braid your hair in cornrows or rock a sleek bun and then cover all your hair with a wig cap to lay the foundation for flawless security. With the wig cap in place, find the perfect position and utilize the elastic band, adjustable straps and combs to achieve a secure and comfortable fit. And then you can use wig adhesive or tape for added security if necessary.

There are some ways to store wigs in the safe place to ensure its longevity:

– Wig stands: Always store wigs on wig stands. This helps maintain the wig’s shape and reduces tangling

– Environment: Store wigs in a cool, dry place away from direct sunlight because prolonged exposure to sunlight can fade the wig’s color.

– Travel: When traveling, transport wig in a sturdy wig box or a silk bag to protect them

It’s generally not recommended to wear a wig when you do some intensive physical activities or swimming because sweat, water and friction may damage the wig or its attachment.

Frequent washing can decrease the lifespan of wigs. It’s better to re-wash a wig if it gets dirty. With a human hair wig, if you wear your wig daily, you should wash every 6-8 weeks or 7-10 wears. And if you use it more seldom than that, plan on washing it once monthly.
