theres really no certain time when the rest of ur pit hair will grow in
but id say sometime between 16-18 yrs old. dont worry dude u have plenty
and before u know it u will have alot more.

You might not exactly grow it all in until your an adult. Yes, it should thicken soon (seeing as you're starting to get it) but I'm not sure that it'll be 100% in until late teens/adulthood.
