What Causes Alopecia?
Five Factors That Affect Your Risk!

From the previous pages in this section, you now know that skull expansion (skull bone growth) is what causes alopecia (baldness) and hair loss in both men and women.

It’s well known that this condition (androgenetic alopecia) is connected to genetics and the androgen (hormone) called dihydrotestosterone (DHT). But exactly how these two things combine to create one of the most frustrating and distressing conditions known to man has been pestering hair loss experts for years.

This page explains how skull expansion finally solves that mystery by asking five very important questions about this type of hair loss. And, as you’ll see, only skull expansion can provide all the answers.


Soon after I started losing my own hair, I decided to approach a hair loss center here in London and ask some in-depth questions. So, take a quick look at the following five questions:

Q1. Genetics: Which genes actually initiate the hair loss process?

Q2. Hormones: How can DHT cause both hair growth and hair loss?
(DHT produces body and facial hair growth from puberty on-wards).

Q3. Rate: Why does the rate of hair loss vary so much?
(Some men suffer rapid hair loss as early as puberty and become completely bald by the age of 30; for others, hair loss doesn’t start until much later on in life, and can be a much more gradual process).

Q4. Region: Why do some people only start losing hair from the front of the scalp (receding temples), or the back (a bald patch), whilst others lose hair from both these regions at the same time, often forming the familiar "male pattern baldness" profile? 

Q5. Remnant hair: Why does "remnant" hair often keep growing?
(Remnant hair is strong healthy hair that continues to grow normally within the hair loss region despite complete baldness all around it – see arrow A in the pictures below).

I believe these questions are extremely relevant to the hair loss process. And, as such, it’s vital that complete, accurate answers are given before any theory can be recognized as the true cause of this condition.

But, the current theory cannot answer all these questions.

Only skull expansion can...


Please note that only very brief answers are given below. For complete answers, read the previous pages in this section or the skull expansion ebook (see next section below).

A1. Genetics: The genes responsible for this type of hair loss are those that determine skull shape.

A2.  Hormones: DHT is a steroid hormone and, as such, will stimulate the growth of hair, muscle and bone. And this includes certain bones of the skull in those who develop hair loss. When the skull expansion process starts causing hair follicles to miniaturize, the body tries to get the hair growing normally again by using the hair growth promoting effects of DHT. So it increases DHT production in the hair loss region of the scalp. But this process (called upregulation or hyperandrogenicity) is unsuccessful. (You can learn why upregulation doesn't work by reading this article).

A3. Rate: The rate of hair loss, when it starts, and the extent to which it develops mostly depend on the shape of the skull. Certain skull shapes will develop hair loss much earlier, faster and severely than others.

A4. Region: Receding temples are caused by frontal bone growth; a bald patch at the back is caused by parietal bone growth. And growth of the frontal and parietal bones together will cause hair loss at both the front and back of the head. This also explains how the familiar "male pattern baldness" profile (horseshoe shape) nearly always seems to develop for most men.

A5. Remnant hair: Remnant hair sometimes continues to grow in areas within the scalp that remain relatively free from skull expansion. This means that hair can sometimes keep growing at the crown of the head where the frontal and parietal bones meet, or at the front where the hairline recedes.

So, there it is.


You should be!

Skull expansion is, without doubt, what causes alopecia and hair loss in millions of men and women around the world. It provides the true underlying mechanism behind androgenetic alopecia and can explain the genetic link to hair loss, how the hormone DHT is involved, and provide answers to those important questions above (something the current theory cannot do).

And, if you're still in any doubt about skull expansion, why not simply contact a hair loss specialist and ask those five questions - I guarantee they will not know the answers!

This Ebook PROVES That Skull Expansion is What Causes Alopecia

For a slightly more in-depth look at this type of hair loss and the skull expansion process that causes it, read:

"Skull Expansion – True Cause of Genetic Hair Loss"

Here are four very good reasons why you should read this free ebook:

1. It fully explains exactly why the current theory is wrong.

2. It proves beyond doubt how skull expansion develops thinning hair, hair loss and ultimately baldness.

3. It reveals just how badly hair loss affected me, and how I eventually managed to find a solution.

4. It also has a nice little surprise right at the end.

How to Stop Skull Expansion and Hair Loss

Is it really possible to stop hair loss and get your hair growing normally again?

Paul Taylor age 46

Well, as mentioned earlier, I’ve suffered this type of hair loss myself.

And it was from my stubborn refusal to go bald (as well as my complete and utter frustration when the hair loss experts I asked were unable to answer my questions) that I began studying androgenetic alopecia – work that was to take me seven years before I finally realized that skull expansion was the reason behind this condition.

And once you fully understand a problem, you can then set about finding a solution.

So that’s what I did!

You can learn what this solution is, and whether it can help you too, by reading the following page:

Final Note:

My research into what causes alopecia culminated in the publication of an article I wrote for the Medical Hypotheses Journal:

Skull Expansion: Alternative Model for the Primary Mechanism of AGA,  
Medical Hypotheses, Volume 72, Issue 1, January 2009, Pages 23-28, Taylor PJ.
