For my
protective styling are techniques that protects the hair (particularly the
ends) from rubbing against clothes, weather, excessive manipulation, etc
My
hair does not grow faster with PS’ing, it grows at the same rate unless I’m
taking vitamins or applying a topical growth air… but PS'ing helps me retaining length,
i.e. reduced breakage.
My options are extension braids and weaves.
Tried LF but the laced caused itching around the hairline.
There are loads of
PS’ing options, I’m sure you’ll find one suitable for you 
Good luck
