is there any benefit to dreading my hair early?

I really don't want short dreads but if it's easier to start my dreads short and let it grow dreaded i would do it. Just wanted to know if there were any pluses or minuses.

short hair shrinks less drasticlkly

I think im gonna let it get to at least six inches.

If you do it with short hair its easier to them going flat !!
