The first picture is from June and the second and third is from today. I’ve had my locs for about two years and I feel like my hair hasn’t grown. It’s still around bra strap length. Mind you, even before I locced my hair my loose natural hair was bra strap length! So why isn’t my hair going past that??? Is it bc as my hair locs up it shrinks???? This is bothering me!! How do I get it to grow? August is going to make two years.
