I wonder if I should cut my hair short permanent or just cut it so it will grow back healthy
dont cut it short.you subconsciously consider "cut it so it will grow back HEALTHY", you like long hair,dont cut at all if not necessary.
Cutting it more often is supposed to make it grow faster. This is what I would do if you're trying to grow it out.
Cut it so it is healthy and if you like it keep it short if not grow it back out again.
