Mom is 4a with very fine strands; Dad is 3b with silky strands...I am definitely a mixture of both-- 4a/3c, with some 3b thrown in to confuse everyone.
My mom almost never relaxed ( a few years on and off; if she wanted a straight look, she pressed). Now that she's 60, she boasts that "she has more hair than most other women her age." Last time I was there she had a poofy salt and pepper fro.
O, S, with fine strands
