Hello Rose, this wig is in the category of "Ready to Ship", if you order this today, we will ship it out as soon as possible when we receive your order. But if you need it before April 6th, we are afraid the time is a bit rush. But with a faster shipping method like UPS, there is a chance, but we cannot promise you that as the shipping time is not controlled by us, hope you can understand. 

Hello sarah, this wig is made of heat-resiting fiber, you can use a hair straighter to restyle it if it is not so straight.（But please make sure the temperature is under 200℃
