Its all depends on were you're starting. If you're starting from a bob cut or a pixie your hair might take longer than others to grow.
It also depends on your diet. If what you eat is balanced with fruit, vegetables, protein and calcium, that should help your hair grow. Iron and vitamin D also helps too.

Pollution and smoking... Hope it helps, have a great day!
