I feel you problems could very well be atributed to the dysfunction of the liver. At least in part.
Constipation might be caused by the lack of bile flow which is caused by clogged liver/gallbladder. One of the functions of bile is to lubricate your intestines. Any amounts of fiber and water would not do this.
Hair problems again, might very well be caused by dysfuntional liver/gallbladder. As we all know liver recycles all steroid hormones. Dihydrotestosterone (DHT), which is very important in the puberty when sex orgnas develop, later in life often become the issue- due to clogged liver, liver cannot properly recycle testosterone. DHT is made from testosterone. Who does the dirty job?- 5-alpha reductase, this enzyme, this protein. This protein resides in the skin (including scalp), liver, prostate, seminal vesicles. So when testosterone and 5-alpha reductase meet you get bad news. And all that also gets us to other processes in the body:
A protein called SHBG (Sex hormone binding globulin) rises as we age and more testosterone is bound up to it, reducing the amount of available (free) testosterone.
More testosterone is converted to oestrodiol by an enzyme called aromatase.
Less testosterone is made by the aging testicles.
It is also DHT taht increases the size of prostate in men. So, enlarged prostate and falling hairs are caused by the enzyme. As it was mentioned you have to look at the bigger picture. It is also very likely in this situation that another enzyme, aromatase converts testosterone to estrogen, a very very powerful anabolic hormone. Estrogen acumulates and robs men further. Oh boy, what a mess!
To me, directly and/or indirectly everything is connected to liver. Among gazillion things that liver performs is to make bile, remove excess of hormones. No doubt, at least in part adrenals and testicles are involved. I mean, really, we are being robed of testosterone: part is made into estrogen, part is into DHT and if left all free testosterone is bound to SHBg.
Have you had you male hormone profile tests done? Saliva tests, of course cause they are more reliable? I bet you have way too much estrogen and way too little testostrone. I did and I had the results I suspected. I don't have balding head yet( but possible) but sex drive is still too low and erection is problematic. And all that is common in men.
No wander all drugs for hair are 5-alpha reductase inhibitors. Hey, but we got stinging nettle, saw palmetto and other things. Zinc is super important since majority of it resides in semen. If you masturbate, take a note of that too. Women loose iron because of mesturation, men loose zinc because of masturabation.
There so many many part to all of that, including candida, that producing 70+ toxins, clogged guts. But it impossible to go around without stumbling upon liver. That's what I would do- take care of the liver, continue tearing appart candida, taking appropriate supplements (inc. vitC of course). By the way, that's what I am doing.
And no wonder Chineese still have say: "good morning, how is your liver"
