How long will microneedling results last

What are the chances the regrowth I have from microneedling my scalp is “permanent”. I have diffuse thinning and microneedling has given me regrowth without any topicals. I am fairly certain that these new hairs will not be permanent. They may last as long as a single hair cycle which is usually 2-3 years for the average young male. This is an educated guess, of course.
