DHT neither explains hairloss nor hair retention

All Males produce the Male Hormone, Testosterone.  Testosterone provides the base for DHT, dihydroxy Testosterone.  The T in DHT is testosterone. If DHT is accepted even for a minute as the cause for hairloss, why should it work at best on less than 50% of the heads. The theory sounds very confused and concocted. 

Not all males suffer from hairloss or male pattern alopecia. Even granting that 40% suffer from hair loss / depletion, others remain unaffected. That is, over 60% males retain the hair / density despite producing Testosterone, which is unexplained ! Is it not open, glaring contradiction / anomaly

For above reasons, DHT theory is extremely porous in my view

 

If there be no Testosterone, should there not be automatic self recovery ?

More importantly, Testosterone production goes down after age 40. The production of DHT also go down. 

So if DHT be the cause, should not some males recover hair on their own after age 40 ? 

DHT theory cannot explain or solve hairloss amongst females

Now look at some Arithmetic. Males account roughly for 50% of the population. It is irrelevant for females. That is, at best, it says it means something to 40% of males or 20% of the population.

Refer to the Press Reports produced at the end of this page or Propecia website. ..." men may have to use it for six months to a year before they learn whether they are among  the half that benefits, Washenik said"..

That means, with impact rate at maximum 50%, it has relevance for only 10% of the total population at best. But, even that is wishful thinking ! For men, Propecia is not a miracle pill. About half who use it, grow varying amounts of hair ' as per Washenik [ Dr. Warshenik is a Bald Dermatologist. He wished to try Propecia when he made the above comments. What happened afterwards is not known to me ]

That is, a porous theory is further weakened / contradicted by the claimed results / impact of Propecia

Evidence available, but not collected or presented - Proscar angle

Proscar of E. Merck is a prescription drug for patients suffering from enlarged prostrates. It is much earlier to Propecia, introduced in 1998. The active ingredient of Propecia is Finasteride. Proscar contains 5 times more Finasteride compared to Propecia.

Persons who use / used Proscar should have got some new hair growth with continued usage / 5 times of dose of Propecia. It is logical to infer that the dosage of Finasteride / Proscar must have given some solid clue to E. Merck about the impact of Finasteride on Hair.

The very fact that Proscar is underplayed

Makes me doubt seriously the dht theory
