The most famous member with many photos is Widowspeak. Widowspeak is on many forums (unfortunately not this one so you're lucky he can't call you a liar too) and his photos are on every forum he belongs too. He is at almost full regrowth at around the 3 year mark.
I won't bother to link to Widowspeak's photos because you've already seen them IF you actually went to the forum.
"Full regrowth" is biologically impossible no matter what treatment he's on. Even if he was taking immunosuppressant drugs like cyclosporine, which apparently grow more hair than anti-androgens, it would still be impossible.
My wager is whatever regrowth this guy
supposedly has is due to other treatments, or he's faking with Photoshop.
Either way HE WILL NOT REGROW ANYTHING FROM CESSATION OF SHAMPOO USE.
I repeat my rebuttal of your crappy theory, point by point:
a. Men went bald in the old days and I said this many times. There were other causes of baldness and the main thing was malnutrition. Back then people had to search for their own food. Bad diets, no food, starvation. You name it people suffered hairloss. I believe the average age of death was in the 30's and younger for cavemen. Speaking of cavemen, I am sure insects and mites also contributed to baldness before shampoo was invented. It was a entirely different time back then.
Male pattern baldness is NOT the same thing as other types of hair loss. Balding men do not 'lose' hair in the true sense of the word, but instead it gradually becomes fine and vellus. The transition of at least some terminal hairs into vellus hairs is a universal physiological secondary sexual characteristic. Clin Endocrinol 1994;40:439¬-57.
b. all men who use shampoo eventually do go bald. The problem with this is people die at all different ages. Some men probaby would of went bald from shampooing, they just didn't live long enough to experienc the baldness. Car accidents, cancer, etc.
The prerequisites for premature androgenetic alopecia are a genetic predisposition and sufficient levels of androgens. Eunuchs and men with 5AR deficiency do not go bald. Every white man possesses the autosomal inherited predisposition, and 96% lose hair
to some degree, but because of the variabity of gene expression far fewer have appreciable premature hair loss. Am J Anat 1942;71:451-¬80. J Clin Endocrinol Metab 1960;20:1309¬-18. Dawber RPR, ed. Diseases of the hair and scalp. Oxford: Blackwell Science, 1997. Ann N Y Acad Sci 1951;53:708¬-28
c. regarding women, see b.
Simply false. The reason why women don’t lose their hair to the same extent as men is because androgen receptor content in female frontal hair follicles is approximately 40% lower than in men, and frontal hair follicles in women have 3 and 3.5 times less 5-AR types I and II, respectively, than frontal hair follicles in men. Journal of Investigative Dermatology (1997) 109, 296–300
d. All men apply shampoo pretty much the same way. They apply it to the front or the top of the heads and according to Cutsinger, this is "ground zero" for the hairloss to occur. Years and years of acid burns will eventually cause a bald spot and once it starts, it spreads, you will get the horseshoe pattern and that's the area where the shampoo is concentrated the most and for the longest periods of time. The back and the sides get very little because of gravity. The horseshoe top is where the shampoo sits flat until water washes it away. You see now.
As Doctor has said, chemicals in rinse-off shampoo products do not have sufficient time to absorb into the skin and, even if they did, there is ABSOLUTELY NO EVIDENCE that they damage hair follicles - quite the contrary, according to some of the information that Bryan has posted e.g. "Induction of hair growth by skin irritants and its relation to skin protein kinase C isoforms." Br J Dermatol 1999 Apr;140(4):616-23.
The reason why the back and sides of the head are not affected by male pattern baldness is because these regions contain far lower levels of androgen receptors. It’s nothing to do with where you start or finish applying shampoo. J Endocrinol. 1998 Jan;156(1):59-65.
e. I can't explain the use of androgen on scalp hair
Exactly. Because you ignore the science.
just like you can't explain why Lawrence, Diamond Dave, Widowspeak, and FirestormUK are regrowing huge amounts of hair by cutting out the suds.
None of you are regrowing hair. Your hair may appear thicker because of the accumulated grease and grime, and you may have naturally reached your eventual Norwood scale rating, but you certainly won't regrow any hair. There is no biological possibility of this happening. At all. Ever. Trust science.
f. There is no proven effectivness except for some peach fuzz and great marketing by the chemical companies to young 20 somethings who don't know any better and are only worried about getting laid so they all get on drugs in order to have sex or to find a mate before they bald. Follow the money trail and you will find a pile a crap at the end of your chemical rainbow.
Wrong. We have evidence from randomised placebo-controlled trials that finasteride and dustasteride regrow hair and prevent further hair loss. This evidence has been subjected to peer review and published in reputable scientific journals.
