Why are my locs soft?(I have 4c hair)

I’ve been on my loc journey for 6 months going onto 7 but i don’t know if my hair is locd yet because it’s still soft when I touch it. And i’m really wondering why and concerned why my hair is so soft. If i’ve been in the game for 6 months shouldn’t my hair be hardened by now? Only a few of them are but most of them are soft.
