Sizing a wig Cap to fit the head. We use the current cap and take in as needed and remove excess material and sometimes hair. We can also add material to make bigger - from front to back and the circumference. If the depth - meaning ear to ear is too small we recommend a new cap. Please contact as if you need to switch the cap completely. Think of a dress - a tailor can make it smaller and take it in or add material and make it bigger. We can take all the parts/hair off the cap and place on a new cap completely (like taking off the beads and details of a dress and putting on a completely new one) This sometimes require use of additional hair so prices vary.
