Hi Steak,
If you have very fine hair we can match it. We will use Chinese Remi hair which is finer than our normal Indian Remi hair. Many people struggle with shaving off their remaining hair for a topper---they've nutured it while it thinned out and now they have to 'bite the bullet' and shave it. But once done and they've got a topper on they never look back.
Regards,
John
