there are a few on here that have claimed better results with high dose dutasteride but later it stops working and they have to increase the dutasteride dose again to get better again and then repeat until up-regulation fucks them. I think its a dangerous thing to risk.Saw many who took Avodart 2.5 mg per day but new hair was not much, but baldness stopped. For new hair, you probably need to add estradiol. Few people tried to increase the dose of avodart. I conclude that Avodart 0.5 mg per day cannot cover the message dht. With increasing doses, the situation improves.
Here's my take on this.. I do not think that testosterone is good for hair, at least not directly. It has been known for a long time, even noted by Aristotle that eunuchs castrated before puberty don't go bald. DHT is much much stronger than testosterone yes, and it is possible that testosterone alone is not strong enough on its own to cause baldness.. but the hormonal profile which is required to Regrow hair is different than which is required to Prevent hairloss. It's much harder to raise hair from the dead.The opinion that testosterone harms the hair is erroneous. Testosterone does not harm the hair. Only dht. The fact is that the CPA is much stronger blocks dht and only this is the reason for success. And to block testosterone makes no sense. This can be verified by increasing the dose of dutasteride. Dgt is very strong and is the hardest to block. There are people with a genetic defect alpha reductase and with a lot of testosterone, but hair does not fall out. I think that testosterone like estradiol has a good effect on hair. Maybe I'm wrong, I do not know. There is something else about this later.
Here's one example:
Genetically Identical Twins, one of them started dutasteride as soon as they noticed signs of hairloss and halted further balding. The other one put off treatment for several years..
"I have now been taking Dutasteride for 6 years and my twin obviously around 11 years. Over time I have not suffered any detrimental side effects (some of the typical negative ones are decreased libido and impotence)."
"It took me a further 5 years to actually be concerned enough to act when my bald spot became a lot more prevalent. I'm sure most men are like me, they wait for clear confirmation that something is happening and then they decide to act as opposed to listening to and dealing with the problem early on. However, the truth is, even though I am balder than my twin brother."

So, the point is that the other twin started dutasteride After losing his hair and it didn't save him like it did his brother.
So, how can it be sure that MAXIMUM results, particularly for Regrowth rather than maintenance wouldn't also require lowering testosterone as well?
Ok, so here's my next point: Testosterone has affinity to the androgen receptor.. DHT is worse than testosterone because it has 2 to 3 times greater activation and stays attached to the androgen receptor 5x longer than testosterone. There are bodybuilders who blast hardcore synthetic steroids, which are not T or DHT, and lose hair because they have affinity to that same receptor. If you have have balding genes and take a steroid as strong as or stronger than DHT, then you are guaranteed to be speeding up the balding process.
If DHT causes 20 times more gene transcriptional activity than T (I don't know the number, just using this as a hypothetical example) then 1 molecule of DHT would be worth 20 molecules of testosterone.
Who is to say that a very high amount of something weaker can't accomplish what a normal amount of something stronger?:

- "during pregnancy, estrone and estradiol production is increased about 100 times over non-pregnant levels. However, the increase in maternal estriol excretion is about a thousand-fold. The traditional view that estriol in pregnancy is a weak estrogen metabolite is not accurate. A weak estrogen provided in high concentrations can produce a biologic response equivalent to that of estradiol."

-hell, this guy even increased his estrogen by drinking soy milk:

However, it's important to note; he was drinking 3 f*****g quarts of it everyday!!!
Ok, moving on to another point:
"In face-skin cells, androgen receptors stimulated by testosterone respond by initiating a cascade of growth, promoting production of a chemical called insulin growth factor (IGF); you might say the testosterone "key" unlocks the door and lets out IGF. Conversely, in the scalp, testosterone activates processes that suppress hair growth, by "letting out" a substance called transforming growth factor, reducing the diameter of follicles to cause thinning, as well as promoting production of oil (sebumn) that can clog hair follicles and stop hair from growing."
https://books.google.co.jp/books?id=XPOaDgAAQBAJ&printsec=frontcover&dq=testosterone+hair+androgen+receptor&hair loss=en&sa=X&ved=0ahUKEwi9nYW5m4HgAhUb97wKHUO8ABoQ6AEITTAH#v=onepage&q=testosterone hair androgen receptor&f=false
And this study here shows caffeine increasing the anagen phase by counteracting Transforming growth factor.. :
"
BACKGROUND:
Caffeine reportedly counteracts the suppression of hair shaft production by testosterone in organ-cultured male human hair follicles (HFs)."
" Caffeine counteracted testosterone-enhanced TGF-β2 protein expression in male HFs."
https://www.ncbi.nlm.nih.gov/pubmed/24836650
By the way, one the effects of Minoxidil is by: "inhibition of TGF-β-induced apoptosis of hair matrix cell"
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5877552/
So, no I sure the hell don't think that testosterone is good for hair..
Especially considering this guy improved his hair situation by having himself physically castrated:

Now, I have yet another point believe it or not.. :
Our hair follicles produce both aromatase and 5ar. Although women have more in the frontotemporal regions than men. estrogen might be the reason for this: "we noticed in 17alpha-estradiol-incubated (1 nM) female hair follicles a concentration- and time-dependent increase of aromatase activity" https://www.ncbi.nlm.nih.gov/pubmed/12190948 However, I haven't found an estradiol incubated study done on follicles from men.
but Also,
"Plucked human hair follicles demonstrate aromatase activity in culture (Schweikert et al., 1975), while a comparison of scalp biopsies from men and women with androgenetic alopecia revealed aromatase levels to be higher in hair follicles from occipital scalp when compared to those from the frontal scalp (Sawaya and Price, 1997)."
"Furthermore, the same study found that aromatase levels were approximately six times higher in the frontal hair follicles of women when compared to men."
So, If you were to take a look at the scalp androgen receptors (of someone not on hormone altering treatments) I doubt if you'd find much testosterone there because whenever testosterone reaches the follicles from the blood stream it will end up being converted into either DHT or Estradiol.. and if you Inhibit 5AR with dutasteride, or etc. Then yes, the rise in testosterone can be good for hair, because you are increasing the amount of T which becomes E in the scalp.
We also know that testosterone has an inhibitory effect on breast development, but if you were to rub topical testosterone gel on your breasts,,.. there's a good chance it will actually make gyno worse because of Aromatase. and that's exactly what happens and is known to happen with bodybuilders who take testosterone for steroidal gains in the gym.
So, if you want to know how good testosterone directly is for hair. then you would have to inhibit both 5alpha reductase and aromatase.
