My sister got the fast growing hair and I got the slow, so it seems to take forever to grow out. It doesn't break off or get split ends, just grows super slow. It does shed alot tho, mostly due to thyroid and other hormone issues. I take biotin and lots of other supplements and it seems to help.
It's kind of stuck just above bra band length wet. I just gave it a trim and will let it grow over the summer and hopefully get some length by fall.
I haven't used shampoo in many years and think my hair grows better and is healthier with condition washing.
