Hair loss: What you need to know about losing your hair and male pattern baldness
Discover the science of hair loss in men, male pattern baldness and what you can do to prevent – or treat – it
Hair loss may seem like something that affects older men but a quarter of us start going bald by the time we’re 30. Often if our Dad or Granddad went bald at a young age, we’ll notice the same bald patches at a similar age, but it’s not always the case.
There’s also a major difference between hair loss, and baldness.
For starters, male pattern baldness is a genetic condition that can’t be prevented. It typically starts with a receding hairline or a circular pattern of baldness on the crown of your head. Yet, if you’re losing your hair in patches, you may not actually be going bald. In this instance, there are things you can do to prevent hair loss.
We should point out that all men go bald. Eventually. You may not go bald until you’re in your 60s or 70s but at some point in your life, you will lose your hair either all over or in patches. It’s nothing to be embarrassed or ashamed of.
After having long hair and curtains at school – it was the 90s, haters gonna hate – we started losing our hair in our early 20s so we get it. We’ve been shaving ever since and have turned it into our statement look – we’ve owned our hair loss, rather than hid from it.
To help you understand a bit more about hair loss, its causes, and treatments, as well as male pattern baldness, we’ve taken a look at the science of hair below.
This is because knowing exactly how your hair grows means you know exactly what you need to do to help it grow faster, or prevent it from falling out, without spending a fortune on products and treatments.
The science of hair
On average, your hair grows half a millimetre every day, which is about half an inch a month, or six inches a year. That’s according to the American Academy of Dermatology. If you have a short men’s hair style, it may seem like your hair grows faster than this but it could also just be because it’s more noticeable. Especially if the growth causes your once styled locks to go out of shape.
Your hair, itself, is made up of – protein, mainly a kind called keratin, natural oils to keep hair flexible, and water. It grows from the bottom of follicles in your scalp, called roots, and these consist of cell proteins.
The type of hair you have then depends on the shape of these follicles, and this is determined by your genetics.
- If your hair follicles are oval-shaped, you’ll have curly hair
- People with straight hair have circular follicles
The shape of your hair follicles also determines how thick your hair is, and how long it can grow.
Blood vessels across your scalp help to produce these cells and your hair becomes visible once it’s long enough to pass through the oil gland, and your scalp’s skin.
However, by this point, your hair is dead – which is why it’s obviously not painful to have it cut. Treating the hair itself can make it softer or less matted but if you’re trying to prevent hair loss, you need to treat the scalp and the follicles first.
What causes hair loss?
As your hair grows, it becomes heavier and pulls on the follicles. There comes a point when the weight of the hair is so strong that the follicle can’t hold onto it anymore and that particular strand falls out.
People with curly hair tend to “shed” hair more than people with straight and this is because scientific studies have found round follices are stronger.
Science suggests we lose 50 to 100 strands of hair every day, and the rate of loss isn’t always even.
Each of the 5 million follicles in our body is working on different timeframes and are at different stages of growth and at various points of our life, certain follicles take a break.
As we get older, some of these follicles stop working (or retire) altogether and this is what causes hair to thin or fall out and never grow back.
As a result, there isn’t a miracle cure, or product, for how to make hair grow faster – regardless of whatever marketing you read – but there are certain things you can do to help make hair grow faster or at least make it grow more healthy.
What is male pattern baldness?
Male pattern baldness is said to affect 30% of white men under 30, increasing to 80% of men over 70, according to the UK’s National Institute for Health and Care Excellence, and it’s largely caused by a hormone known as Dihydrotestosterone (DHT).
DHT is synthesised from testosterone, by an enzyme known as 5-alpha-reductase and this enzyme is found in the dermal papilla at the base of the hair follicle.
Black and Asian men do suffer from it, but it’s either less likely or it happens later in life.
When this enzyme is synthesised, it reduces the number of dermal papilla cells. This reduction ends up shrinking the follicles and stops hair growing as thick, or as long as it used to. When these cells drop considerably, the follicles will stop producing hair altogether.
This is largely why many men can delay when they’ll go bald, but if they’re going to go bald anyway they will eventually, regardless of any intervention.
How to spot hair thinning
Hair thinning is always gradual, no matter what the cause, but for men – particularly with shorter hairstyles – it can become apparent quickly.
- Hair is not growing as long as it used to
- Parting is wider
- Scalp is more visible, especially around the crown
- Recession at the temples
- Loss of density the frontal hairline
- Reduction in the thickness (volume) and length of each strand
According to the experts at Philip Kingsley, the best treatments for hair thinning usually involves hair follicle stimulants, such as minoxidil and methyl nicotinate, stress management (stress can raise androgen levels in your body), and scalp drops containing hormones.
