Hair Loss and Progesterone

I have been having hair loss and hair thining for about 15 years now. I had my thyroid removed in 2004 and I am taking thyroid medication to replace the TSH. I read that TSH, DHT and Progesterone have an impact on hair loss/thining in women.

No dermatologist or general practicioner was able to help my hair loss/thining. After I read about the high impact of hair loss (75% of hair loss is due to low progesterone according to that articel) I went to the doctor and asked for a blood test on my progesterone since no doctor had ever checked it before. My progesterone level came back at 0.8! which, according to what the doctor told me, is way too low and he gave me a progesterone medication.

The progesterone level is supposed to be between 3.3 and 26. So my progesterone was almost non-existant. I am hoping that the hair loss and thining of the hair will improve in time. However, I realize that 15 years of hair loss and thining are not going to be fixed in one month, according to the article, it takes a long time. But I am not giving up hope.

Hair Loss and Progesterone
by: Wray

A lack of progesterone can lead to hair loss, due principally to a relatively high oestrogen level. Excess oestrogen is converted into androgens, it's these which cause the hair to fall out. Supplementing with progesterone suppresses both the oestrogen and the androgens allowing the hair to grow back.

Your level is very low, due undoubtedly to the stress you've been going through with your thyroid. Stress drops progesterone levels sharply. You say you've been given progesterone medication, I do hope it's not a progestin and is progesterone. Please bear in mind if it's oral progesterone most of it is destroyed as it passes through the gut and liver, so very little reaches the cells where it's needed. The best routes are injections, suppositories or creams. Please consider taking 2000mg/day N-acetyl cysteine and 2000mg/day inositol (a B vitamin), often called the anti-alopecia vitamin. Both these do help to restore hair growth. Take care, Wray

help please 62 hair loss now on hrt
by: Wray

Hi Kathy I don't believe any woman needs extra oestrogen, we make more than enough in our fat cells. It will also suppress any progesterone you have. For more info please see here.

I assume you are taking oral progesterone, which is not the best delivery system, as most gets destroyed in the gut and liver. I think this is the reason your progesterone level is low, it would be higher if you were supplementing with suppositories or a cream. It's also best to divide the amount into a minimum of twice a day, levels drop too low before the next dose. Oestrogen also suppresses thyroid function, whereas progesterone suppresses oestrogen and has a slight stimulatory affect on the thyroid. Please consider taking 2000mg/day N-acetyl cysteine and 2000mg/day inositol (a B vitamin), often called the anti-alopecia vitamin. Both these help restore hair growth. I also suggest you have a vitamin D test done, a low level reduces the benefits of progesterone and slows the thyroid down. For more info please see here.
I've given links to Medline below so you can check your levels.

Hair loss with progesterone alone.
by: Anonymous

I am in chemo induced menopause. I've been on 100mg of natural progesterone cream daily with no estrogen. Recently my hair has been falling out in my temple area -- male pattern baldness. I've read that this can be from low estrogen. I know my estrogen level is almost non existent. Do I need to add estrodiol into my regimen? Progesterone alone is not helping. I don't think increasing progesterone alone will help since I don't have any measurable estrogen in my body (blood tests have showed this).

How much estrodiol should I take. Thanks!

no estrogen
by: Michelle

Hi, I posted above (chemo induced) and did not yet get a response. I've been on 150 of progesterone for 6 months. I do show a low level of prog in my bloodwork, but no estrogen. Do you ever recommend taking estrodiol, even when a person has none measurable? I'm having hair loss and I wonder if it could be from no estrogen. Does too much progesterone cause hair loss? I'm considering adding estrodiol to my daily regimen. I'd love your thoughts on this. Thanks!

Hair loss with progesterone alone.
by: Wray

Hi Michelle I'm sorry I can't get to answer the questions as quickly as I'd like to, there are so many now. I would never recommend oestradiol to anyone, as it's implicated in Cancer. Also see our page on HRT. The oestrogen which is tested for is always oestradiol, very rarely oestrone or oestriol. So I'm delighted your level is low, specially as you've had cancer. If progesterone caused hair loss, every pregnant woman would suffer form it, as we make over 400ng/ml each day in the third trimester. The reverse occurs in fact, as hair growth during pregnancy is usually wonderful. The enzyme 5 alpha-reductase converts testosterone into dihydrotestosterone (DHT). DHT is implicated in alopecia. Progesterone inhibits 5 alpha-reductase activity by 97 +/- 5.3%, see here. You might like to read these comments for encouragement, see here and here. Please have a vitamin D test done, this nutrient is always low in cancer. In fact it's been found that over 20 different cancers are in part caused by a lack of vitamin D. For more info see the Vitamin D council and GrassrootsHealth websites. Plus these excellent video's here, here and here. Vitamin D is essential for the anagen growth phase of hair. Plus a lack of vitamin D reduces the benefits of progesterone. Take care Wray

help with hair loss
by: Susan

Hello Wray,

I have been taking bioidentical progesterone cream for a couple months now in hopes that it will help my hair loss. I am wondering about the dosage and days to take it. Everything I have read says that you should take a break for a few days each month depending on whether you are still menstruating. Is this true? I am reading conflicting information.

natural progesterone?
by: Anonymous

Has anyone used a natural/OTC product or cream or vitamin that has helped with hair loss due to low progesterone? I'm 40 and the initial battery of tests found no reason for the hair loss outside of low vitamin D and stress. But I do know I have a luteal phase defect through a biopsy. I used progesterone and it helped sustain my subsequent pregnancies, but I'd like to find a natural way to treat it. I just started taking black cohosh.

Hi there We do have a page on Hair Loss which explains why and how it can occur. It also lists a number of nutrients which can help too. High androgen levels are but one cause of hair loss. Please look through the page and see if you can find a clue to what's causing yours, before having your hormones checked. Take care Wray

postmenopause progesterone levels
by: Anonymous

Hi Wray,

I just went to see en endocrinologist. She didn't seem to know much about anything. She goes strictly by numbers. She told me that once postmenopausal, women do no need any progesterone and that our levels are and should be zero or close to that and there is no such thing as a ratio of progesterone to estrogen when we get older.


Mar 21, 2013
Cananyone help!
by: Wray

Hi Kay Oh so the first two are progestins, both have androgenic properties, so would increase Hair Loss. The Crinone is progesterone, which one were you using, the 4% or the 8%? Both will give you too low an amount, the 4% 45mg and the 8% 90mg. The Prometrium is also progesterone and is usually a 100mg oral capsule. Is yours? If it is you will be getting so little it will make symptoms worse, "The liver and gut region removed a mean of 96 per cent of the progesterone entering these tissues", see here. In fact the same applies to the Crinone too, although you are getting the full amount of progesterone it's not enough. Please read our page on hair loss, it tells you how much progesterone to use, and the other nutrients which help. vitamin D is an essential, please have a test done. Take are Wray

postmenopause progesterone levels
by: Wray

Hi there Interesting! Our fat cells make oestrogen, oestrone, until the day we die. Plus we are all getting extra from the environmental oestrogen mimics which are found everywhere, see Our Stolen Future. We still secrete progesterone, but not from the ovaries. The brain, central and peripheral nervous systems and the adrenals, but not much. So it's very possible to have a skewed ratio in menopause. I wonder why it is that so many menopausal women find such relief when using progesterone. Maybe it's the placebo effect, if so that's also fine, at least they feel better! Take care Wray

medications making me lose hair
by: Anonymous

I am taking Warfarin, Metoprolol and propafenone for a-fib. My hair is falling out...doc says probably from stress. I think it is from meds. Will progesterone cream help and are there side effects from that.

medications making me lose hair
by: Wray

Hi there Has anyone checked your oestrogen and progesterone levels? Oestrogen not only causes clots, but heart arrhythmias too. It doesn't appear that the propafenone causes hair loss, although it comes with a long list of adverse symptoms, see here. I see the Metoprolol is given to treat someone with a long QT interval, this drug does cause hair loss, plus many more adverse symptoms, see here Oestrogen causes prolongation of the QT interval, which results in palpitations, arrhythmia, Torsades de Pointes and sudden death. Whereas progesterone shortens the QT interval, see here, here, here, here, here, here, here, here, here and here. These symptoms occur far more frequently in women who naturally have a long QT interval, rather than men who naturally have a short QT interval. Progesterone can help Hair Loss, so too can vitamin D. Both prevent clots, vitamin D appears to play a role in the QT interval too. Has anyone checked your vitamin D levels? Please have a test done if not. So to answer your question, progesterone can help but as it thins blood, prevents clots, plus shortening the QT interval, I would use it under your doctors supervision. Take care Wray

Currently using 250mg of Prometrium
by: Kendra

I am currently taking 250mg of Prometrium daily. I am still producing estrogen so I do not take additional and my testosterone is low enough that the doctor put me on it and prescribed spironolactone to block DHT. My vitamin D is low and I take 10,000 iu's daily. I also take B12 Methylate. I take 500 mg of Metformin now upped to twice daily because I am insulin resistant. My hair has been thinning for years at my temple and the follicle has thinned. Just wondering if I am on the right track and would appreciate your input.

by: Wray

Hi Kendra Oral progesterone is the least effective Delivery system, "The liver and gut region removed a mean of 96 per cent of the progesterone entering these tissues", see here. So you are getting very little. I would recommend changing to a system which delivers progesterone more effectively. Daft to give you testosterone, then give spiro to block it! Progesterone is as effective as spiro in inhibiting 5-alpha reductase, see here, h

hair loss and menopause
by: Anonymous

I don't take any prescription drugs, however I take supplements from the local health shop. My hair has been falling out and thinning for 8 to 9yrs. I used to have beautiful hair and now I have ugly hair - or rather what's left of my hair.

I also have painful joints, especially small joints, especially knuckles. I am in my early 50's. I used to have perfectly regular normal periods which suddenly stopped. My energy dissappeared like a light switch going off.

I live in a country with no sun. I take Vit D currently 80mg per day. Some red clover because I get the hot flushes but not as badly as others describe it. I use over the counter yam creme. I think it would be cheaper just to use bio-identical hormones. My biggest issue is that I don't like going to doctors as I never get anything from them that works, and they have ridgid guidelines to follow. I would however, like to find a professional - even alternate - that I could consult.

I like excercise, love fresh raw fruit and veg, and am thin.

Any advice would be much appreciated.

progesterone does cause hair loss
by: Rio

hi there I have seem hundreds of comments saying that progesterone does not cause hair loss. It certainly does if you take loads of it even bioidentical types. The reason is that anybody who takes progesterone for long will create an imbalance between estrogen and progesterone and thereby cause hair loss. I have loads of friends all in menopause who have had the same experience. You must add bioidentical estrogen if you are taking progesterone. then you will restore hair fully. I take estrogen only for 10 days and progesterone daily. I nearly lost all my hair by believing that you can just take progesterone.Its a myth. U need the 2 in balance. Less estrogen and more progesterone. U can check it out every 6 months and soon you will know what is going on and adjust dosage. Good luck.

Hair loss due to progesterone
by: Anonymous

I agree with Rio. I was on .025 of Bi-est with 100 mg capsule of progesterone. I had a full head of hair. My Dr increased my progesterone to 100mg progesterone cream. I immediately lost a ton of hair. You need a balance

Hair Loss, Imbalance of Hormones
by: Anonymous

You absorb more cream than what is in the capsule of progesterone, so if your Dr. gave you the same mg, it was way too much and why your hair fell out, from what I have read.

Low estrogen does cause hair loss and vaginal dryness and dry eyes hence I know bio identical estrogen had to be added to my bio identical progesterone.

I didn't have high testosterone or dht etc., I was low in those but you may want to check cortisol levels because high stress can cause high or low cortisol and cause hair loss. B vitamins and Vit C and learning to get 8 hours sleep a night are great for cortisol/adrenals.

I have learned it is all about BALANCE in all hormones and too much or too little can cause hair loss.

Also make sure your THYROID TSH, FREE T3 FREE T4 are tested and that your frees are not bottom of normal, but midrange.

Like many my hair loss slowed down but I waited too long to address don't give up.....

Hair Loss on Progesterone
by: sdp10112

I have been losing hair steadily for a year now. I am on the Vivelle Dot .1 estrogen for vaginal dryness, etc. It has definitely helped many issues, however, hair loss continued.

A Dr. added 150 mg of progesterone cream and the shedding is quadruple what it was before adding the progesterone. Was the dose too high to start out on? I cannot get the shedding to stop. I took the cream for 5 weeks and have been off for two weeks but shedding is not stopping.

Any suggestions would be greatly appreciated. I was really hoping from all I read that this would be the answer. My last two Dr. visits explained it can down regulate into testosterone or estradiol.

I am so confused. Thanks to anyone for a response!

Hair Loss on Progesterone
by: Joy

Hi sdp10112

Yes I agree, hormones are very confusing and often made worse by incorrect advice given. If you stop using the Vivelle Dot your situation will improve. Are you sure that your doctor gave you a natural progesterone cream with no parabens, chemicals, estrogen and or testosterone? If not, then it would be progestin which is a drug. Please read the HRT page given below and read up on the side effects of Vivelle. No women needs to take extra estrogen as there are well over 100 estrogen mimics in our environment as it is, why take more?

Between 100-200mg natural/organic progesterone cream is needed daily, more if symptoms are severe. Natpro Progesterone Cream when inserted in the vagina at night is excellent for dryness and inflammation without all the side effects. Please read the How to use Progesterone Cream page.

Here is the steroidogneic pathways of our hormones explaining how it all starts and ends.

Cholesterol → Pregnenolone → Progesterone → Corticosterone → Aldosterone

Cholesterol → Pregnenolone → Progesterone → 17-OH-Progesterone → 11-Deoxycortisol → Cortisol → Cortisone

Cholesterol → Pregnenolone → Progesterone → 17-OH-Progesterone → Androstenedione → Adrenosterone → two further hormones
Cholesterol → Pregnenolone → Progesterone → 17-OH-Progesterone → Androstenedione → Testosterone → DHT
Cholesterol → Pregnenolone → Progesterone → 17-OH-Progesterone → Androstenedione → Testosterone → Oestradiol ⇄ Oestrone → Oestriol (also Oestradiol → Oestriol)

There is a further steroid pathway which doesn't involve progesterone……
Cholesterol → Pregnenolone → 17-OH-Pregnenolone → DHEA → Androstenediol → Testosterone → DHT.

Please also read the Hair Loss page, there are many things that can cause it. Thyroid for example, have you had this tested?

A Vitamin D3 deficiency reduces the benefits of progesterone, do you know what your level is? Co-factors are needed.

If you have not done so already, please read the advice given on this thread by Wray and hair loss, I can't add anything further to what she has already advised.

Please read these pages and the references as they will help you to understand about the benefits of a natural progesterone cream and what is needed.

Estradiol 0.1pg/ml, Progesterone 92.7 ng/ml
by: ChristiNA BT

I am not sure if estrogen and estradiol are considered the same thing, but I am losing massive amounts of hair every day (jam-pack a ping-pong ball). Was my estrogen level 3 times the normal level for me, being 58 yrs old, 5 years postmenopausal?

I started taking 100mg oral progesterone twice a day a week ago, haven't noticed a change yet, but am concerned about side effects; it definitely makes me sleepy, and I already had baby hairs over most of my face and brittle nails, but I don't want to make those tho, losing my long, thick, healthy hair has definitely been more depressing!
