Hello , ((Me 34 year old women with hairloss since age 29, probably Androgenetic Alopecia (triggered by high free androgens as I have PCOS insulin resistance) , woolly, thick blond , wavey hair, turned thinner lately)) I have posted this a few times but still at a loss to what it is. :lost: Most of my hair (not all) have funny ridges of kinks on them. When I feel the single hair with my fingers, run my fingers along it, there are lots of small little bumps or kinks in it. Little tiny ones, if I look closely maybe the hair is twisted but there are definate bumps or kinks, ridges.. It is driving me CRAZY. :badmood: I tried to look it up on the internet and the closest thing I came to was either: 1) APKH - acquiared Kinkiness of the Hair Syndrome - which is rare and usually starts in pre pubescant males ie age 12 or 13 and not good news as it usually heralds very SEVERE Androgenetic Alopecia coming and hairloss (that did not make me happy). 2) Pili Torti - look it up on internet On some of the hairs, the part nearest the scalp ie newer hair looks smoother and on the end I can see the ridges.. this makes me think something has changed recently. I was diagnosed with insulin resistance last year and have been on metformin for 9 months now.. perhaps now my insulin and glucose levels are down this has been preventing the ridges or bumps on hairshaft happening... I don't know but I'd love to find out what the hell this is!! :lost: Please reply if you have this or have had this!!! Thank you.
