I measured and for me once I get to APL I am five inches from full BSL. So try to measure from your armpit to where you consider BSL on yourself and estimate how long it takes for you to grow that many inches. ]
What she said
It took me about 9 months. But because BSL really measures different on every one I would measure where you currently are now to get an estimate based on your minimal hair growth pattern. It may not be as far off as you think.
