Hi DR Rassman. Thank you for providing this very informative blog.
I’ve wondering about this and trying to find the answer on the internet for ages – sometimes when I rub my head in the morning I see some slightly thinner hair than my normal healthy looking ones. I went to the derm and did a miniaturisation test and had less than 10% miniaturisation. The derm said I am not balding, however when I see these slightly thinner hairs I get worried…
So I guess my question is do these slightly thinner hairs (intermediate?) grow on a non balding scalp? They grow just as long as my normal hair and are same thickness throughout the strand.
If you have less than 10% miniaturization and your dermatologist told you that you are not balding, I would stop worrying. Non-balding people shed about 100 to even 200 hairs a day. Perhaps you’re seeing hairs going through various growth cycles?
If there is any doubt, then have a bulk measurement of your hair done, which will show beyond any doubt if you are thinning or balding. If you have miniaturized hairs, those hairs will not grow at the rate or to the length of normal, non-miniaturized hairs.
