Where did you see anybody saying men and women in their 20s have the same rate of balding?? I said "older" in all of my posts, didn't I? Also, the so-called MPB in women does not look like the males' - unlike the male' MPB the females' is diffuse and non-localized. That does not prevent the studies still calling it MPB because it hormone driven and likely the of the same etiology as males'.
So you propose the additional factor I mentioned in my post above is progesterone - and this has also been proposed as a reason for why women live longer than men. But if women have higher levels of unopposed estrogen (and autoimmune diseases etc. that are said to be caused by it) than men, then this also doesn't make any sense to me. Unless it's the absolute amounts that are important as well, but Peat never talks about that, at least as far as I know.
I agree, it would seem like that. And if MPB was metabolism related, I'd hope to see some amazing before/after pics in a place like a RP forum, but there's a lack of them even here...I honestly am just guessing.
It definitely seems MPB is vastly different from diffuse thinning/hairloss, as I've honestly never heard of anyone regrowing a full head of hair after years of regular MPB.

If it did, you'd probably see a lot of men here either completely stopping their hairloss or experiencing regrowth. If there are and I missed their threads, my bad.
I would love to be proven wrong on this, as I do suffer from MPB.
Don't get me wrong, I'm trying to raise metabolism myself and feel that I'm better off for it. It's just that I'm majorly confused on this topic, it's THE one thing that bothers me about Peat's work (which normally makes a lot of sense). Like why do women live longer, why do they have faster heart rates, why do they not go bald as often as men IF they are 5-10 times more hypothyroid than men and have more estrogen-related diseases? I feel that this has not been adequately explained around these circles.
Perhaps it's the iron that interacts so dangerously with a low metabolism/PUFAs (women have less of it due to menstruating)? Perhaps a lower metabolism is protective in the face of a nutritionally inadequate diet?
But you imply men's and women's balding has the same cause though, and this cause being hypothyroidism.
Women are more affected by hypothyroidism by men, and earlier in life.
The logical conclusion from this would be that more women would be losing hair than men, and earlier in life.
Am I missing something here ? Seems like a huge piece of the puzzle is missing, yet the title of this thread is "Hypothyroidism [...] causes balding."
Looks to me like women baldness after menopause is unrelated, or not strongly related at least, to "MPB".
You say it yourself, it's not the same hairloss (diffuse and non localized for women).
To me, this baldness after menopause is most likely strongly related to hypothyroidism indeed, as hypothyroid men experience the same baldness pattern (diffuse).
But saying hypothyroidism causes balding, as in every type of baldness, just seem like over-simplification.
haidut I think you're still misleading serum DHT with tissue specific activity -which highly depends on local 5α-R2 density-, and still relying on that relationship, to continue supporting the idea that DHT has nothing to do with MPB (MPB =/ general hairloss).
DHT is not a bad guy at all, but its a key actor on genetically predisposed individuals for MPB; again --> scalp 5α-R2 density. This is FACT and deniyng it is blindness. I think this is part of the binary mindset around here... DHT is good for all and cures everything, estrogen bad and cause of all maladies.. and so on. Ok, im exagerating but you got the idea.
Regional scalp differences of the androgenic metabolic pattern in subjects affected by male pattern baldness. - PubMed - NCBI
Regional differences in the androgen metabolism were established in alopecic and non alopecic areas of patients affected by male pattern baldness (MPB). 5-alpha-reductase (5-alpha-R) activity was measured by the formation of dihydrotestosterone (DHT), using 3H-testosterone as substrate: this activity was higher in the alopecic areas (3.4 pmol/g tissue/h) than in the non alopecic skin (1.5 pmol/g tissue/h). 3-alpha,beta-hydroxysteroid oxoreductase (3-alpha, beta-HO) was studied using 3H-DHT as precursor and measuring the corresponding formed 3-alpha- and 3-beta-androstanediols (alpha DIOL and beta DIOL). The beta DIOL was the predominant metabolite and total 3-alpha, beta-HO activity was higher in alopecic skin (12.4 pmol/g tissue/h) than in non alopecic areas (8.4 pmol/g tissue/h). Also 17, beta-hydroxysteroid oxoreductase was measured using either testosterone or DHT as substrates: androstenedione formed from testosterone was higher in hairy skin (12 pmol/g tissue/h) than in alopecic areas (6 pmol/g tissue/h); androstanedione formed from DHT was also higher in non alopecic areas (8.1 pmol/g tissue/h) than in alopecic skin (2.8 pmol/g tissue/h). The greater formation of beta DIOL in the sebaceous glands-enriched alopecic skin supports the hypothesis for a specific role of this metabolite in the control of the sebaceous activity.
Please stop arguing that DHT has no significance in MPB becouse serum levels don't correlate. Thats a blatant falacy, obvious it doesnt correlate becouse serum DHT levels have little to do with MPB. Autocrine formation from local tissue enzyme DOES. Im not saying hypothyroidism does anything of help with it, but it has more to do with GENERAL hair-loss, which is not the same as MPB.
If you understand that a male can develope gynecomastia having completly normal serum e2/prl/prog. levels then you can understand this. Or would you say... oh no, the gyne has NOTHING to do with estrogen becouse his blood levels are OK.
Ronaldo, 39, stopped playing soccer from being too hypothyroid. Still has a "perfect hairline".
So because in old age, some women have their hormones turn havoc, suddenly male balding isn't male at all ? Even these women retain a large area of hair follicles even if dense, millions of men completely lose their follicles and at a much younger age yet it hits them harder than the worst worldwide cases of bald women.
So if hypothyroidism is supposedly always a factor in MPB, then what's the explanation in my case? Like I said, my TSH has tested below 1 since my teens, and I'm in the upper quartile for T3 and T4. Admittedly I've had some problems over the last five years which makes me question the labs a bit, I'm frequently chilled now even though my oral temperature is in the 98's, and armpit temperature is usually between 97.8 and 98. However, in my late teens when my hair loss started, I weighed 120 lbs. soaking wet at 5'10", I'd sleep with my window open in the dead of winter, and play in the snow in shorts and a t-shirt. If I stayed in an enclosed room for a little while, people would comment how much warmer I made the room. It's hard to believe I was hypothyroid back then when my body was like a furnace. I definitely think something is amiss with my hormones, but I'm not sure hypothyroidism is part of it.
Always warm back then, and my resting heart rate was in the 70's.Sweating profusely like that is a sign of very high adrenaline. How were your extremities (hands, feet) in terms of temps?
DHT (and DHEA) is probably there just like cholesterol in CVD - as a bystander and trying to repair the damage.
@mayweatherking I have had a similar experience as you. I have diffuse thinning hair loss and I can't seem to stop it. I have seemingly tried everything 'peaty' and nothing has helped. My "itch" has gone significantly down when my diet is peaty perfect but the hair loss continues...I will say I am probably not getting enough protein and most days I barely hit 2000 cals but I just can't seem to eat more than that! It's been really hard getting my appetite up especially eating 'peaty' foods. If I could eat cheeseburgers and pizza every day I guarantee I would hit at least 2500 cals per day. I am currently taking very small amounts of T3 and a small nibble of T3/T4 before bed...anything above a small nibble gives me adrenaline symptoms.
I experience the itch after orgasm as well. Your theory about zinc seems interesting as I've read on forums that one loses a lot of zinc through ejaculation (I haven't read any studies on this so I can't confirm the validity of these claims). Although I eat oysters almost every day so I should have sufficient zinc in my system at all times... The only thing I can think of is we are somehow not absorbing the nutrients properly when we eat - Due to endotoxin?? I have even tried 2 weeks of penicillin. I feel like it helped a little bit but it definitely didn't solve anything for me. Maybe I need another round to get rid of the endotoxin?
Cows milk doesn't digest well with me but I can tolerate Goat's milk - it's hard for me to drink a half gallon of milk a day...
I'm curious of how much Vitamin A people are taking who have stopped their hair loss?
Also my scalp (galea) is much stiffer than my sides and I am going to make a concerted effort to massage my scalp daily and see if this helps - maybe inversions as well. Has anyone had luck with inversions?
- I feel like this guy has had legitimate success with his exercises. Watch this subsequent video as well (his hair looks thicker and more filled in) -
Just know you're not a lone @mayweatherking and we will get through this.
