DHT is short for DiHydroTestosterone which is just one of the testosterones we have within our bodies. 
The main testosterones we normally think of are total testosterone and free testosterone.  
The testosterones as a group are also known as Androgens or the male hormones, even though women do in fact have these as well.

You can think of DHT as the bad testosterone.  While we do need it when we are young
- it is the hormone that helps male children to develop in the womb and also lets us know when it is time to go through puberty,
it only causes us problems after that.  

Where does DHT come from you might ask?

There is an enzyme within our bodies called 5-alpha-reductase that turns total testosterone into dihydrotestosterone (instead of free testosterone) by combining it with free radical hydrogen ions in our system. About 70% of us are born with a reductase enzyme that has a small piece missing.  When this piece is missing the enzyme becomes overactive and not only creates more DHT than we need, but even worse leaves us with less free testosterone. 
Free Testosterone is the hormone that provides us with energy, libido, the ability to build muscle, strong bones and a healthy cardiovascular system.

Note that its not just genetics at play here.  Lifestyle choices such as nutrition and habits also impact how overactive our reductase enzyme can be
and how much testosterone we have to play with in the first place.

So does this mean the wrong diet can contribute to our thinning and balding scalps.  Absolutely yes!

So If I am suffering from hair loss, is there something that can be done about it?

The answer is yes, but it’s not quite as easy as you might think.  

Some Venture Capitalist funded startups would have you believe it’s as simple as buying generic DHT blockers created over 38 years ago online and having them delivered monthly to your door.   What I and many of you too have found, is that solution can in fact provide a large number of men with some very negative side effects.

So what is the answer?

The answer is that while DHT does contribute to your hair loss (in varying amounts by individual) there are actually a number of both genetic and lifestyle factors that impact both your hair and overall health, and that a one size fits all approach is not the solution.  

While researching for my hair loss medicines reviews report, I was lucky enough to come across Dr Nettles and his Stop and Regrow solution.
Dr Nettles created his Biochemical Report Card to thoroughly analyze both your lifestyle and genetic contributing factors and enables him to create a personalized holistic plan designed to stop hair loss and get you so healthy your hair will regrow on its own.
