Hi, i think you are correct. Curl definition increases as your hair grows longer.

My 4b/3c hair has more spirals now than before and my waves are more defined. There are many things that I suspect cause this --

vitamins, diet and exercise
the weight of my hair has increased

i use sulfate free shampoo and i use sulfate free smoothing conditioner, which i rinse out after a few minutes.
i use a small amount of curlaway, cool water and 2 tsp of jojoba oil to detangle my hair. then i use some more natural oil (like olive oil) and band and let my hair air dry. once i wrap my hair after this (for about 15 minutes), i start seeing waves in it. i open up my hair and let the hair air dry.
after the hair has dried, i apply some pure unrefined shea butter (for shine and smoothness) to each section of hair and i flat iron my hair. every night i loosely band my hair and wrap it with a satin scarf.

if my hair gets dry by mid-week when i am in a hurry and i need to move at lightning speed -- i may use a small amount of mixed chicks leave in conditioner. then after 5 mins i use my conair hot air brush/ iron (model 160 -- such a simple tool but i love it) to smooth the front of my hair only and then wrap my hair with a satin scarf. my hair becomes soft, smooth and shiny again.

all the stretching and smoothing and the products & lifestyle have made my curls more defined over time.

it is easier and faster for me to take care of my hair.
