There is, without doubt, a link between hair loss and food. But, can a poor "junk food" diet actually cause hair loss?
It has long beenknown that DHT (dihydrotestosterone) is connected to androgenetic alopecia which causes thinning hair, hair loss, baldness and, quite often, distress and even depression.
Here's how DHT is involved in the relationship between hair loss and food:
DHT is formed from testosterone - a derivative of pregnenolone which, in turn, is derived from cholesterol. And, as you probably already know, cholesterol, is mostly produced from the fat you eat.
Not only that, but any food surplus to your body's energy and nutritional requirements can be converted into fat for storage. This includes protein and carbohydrates (including sugar).
This fact obviously places great emphasis on the need to follow a balanced diet - something far too few people manage to do.
Poor lifestyle habits can compound this problem further - a lack of exercise means that any extra calories you consume will be converted into fat rather than used to produce energy.
So, if you eat too many calories, it's easy to see how your DHT production can also increase. And fat is more calorifically dense than any other food type. All this, of course means that, if you already suffer male pattern baldness, your junk food diet is likely to make it even worse!
DHT will also increase sebum levels. Sebum is designed to protect your hair. However, only small quantities are needed and so, if too much is manufactured, it will be considered as a waste product by your body. Sebum is also formed from cholesterol. So, if the fat you eat is surplus to requirements, then your body can try to remove some of the excess as sebum via the follicles of your skin. (In fact, the skin is often referred to as "the third kidney" because of its ability to excrete excesses from the body).
So, can this hair loss and food connection actually trigger male pattern baldness?
No, and these are the reasons why:
1. There's a huge number of people who enjoy a junk food diet, but also enjoy a full head of hair. Many may even be grossly overweight, or at serious risk of developing diabetes, cardiovascular disease, etc, but despite such high fat and sugar consumption, they still remain completely unaffected by male pattern baldness.
2. Excessive fat consumption within our diet has only been a relatively recent problem (certainly no more than 100 years) but hair loss has affected our species for thousands of years.
Also, this theory fails to answer these questions:
Q1. Why does remnant hair sometimes last long after baldness has developed? (Remnant hair is thick, strong, healthy hair that grows within the MPB region despite extensive hair loss all around it).
Q2. Why do 20% of men start losing hair at puberty, whilst others don't start until much later on in life?
Q3. Why do some people lose hair from the front, back or both these regions of the scalp?
Q4. Why is it that hair can fall faster in one region of the scalp than it does in the other?
Whilst the hair loss and food theory can't answer these questions, skull expansion can...
Skull expansion (skull bone growth) is now (slowly) being recognised as the true underlying mechanism for androgenetic alopecia (Medical Hypotheses journal Volume 72, January 2009, Issue 1, Pages 23-28).
New self-help techniques have now been developed following the discovery of skull expansion.
