I start growing when I'm informed I have a new grand baby on the way. Then by my grand baby's 1st birth day, it's long enough for the minimum 14" inches.How long did it take you to grow it out? My family (Dad and I) grow hair stupid fast. He's 95 y.o. and severely malnuourished, now on hospice care, yet his hair and nails grow VERY fast. He gets scraggly and needs a cut every month.
