Hair Thinning: What's Really Happening and How We Can Help

What is Hair Density?

Hair density is simply how many hairs you have per square centimetre on your scalp. Most of us have somewhere between 100,000 and 150,000 hairs on our heads – that’s roughly 150 to 200 hairs squeezed into each square centimetre. Of course, we’re all different – genetics, whether you’re male or female, and your age all play a part.

Now, to really understand what’s going on when hair thins, you need to know about the hair growth cycle. Think of it like this – each hair follicle goes through three stages:

• The anagen phase: This is when your hair actively grows – usually for 2 to 7 years. Your hair grows about 1 cm each month during this time (yes, we’ve all tried to measure it!).
• The catagen phase: A quick transitional period of 2 to 3 weeks when growth stops and the follicle starts to shrink.
• The telogen phase: The ‘resting’ phase lasting about 3 months, after which the hair falls out naturally and a new one starts growing.

Here’s what’s fascinating: at any given time, about 85% of your hair is actively growing, 1% is transitioning, and 14% is resting. This is why it’s completely normal to lose 50 to 100 hairs daily – honestly, don’t panic when you see them on your brush. The trouble starts when this natural cycle gets thrown off balance, with too many hairs going into the resting phase or the growth phase becoming shorter.

What Causes Hair Thinning?

Hair thinning rarely has just one cause – it’s usually a combination of factors working together. Let’s break down the main culprits.

Natural Ageing

As we get older (and don’t we all?), our hair growth naturally slows down. The growth phases become shorter whilst the resting phases stretch out. The result? Fewer hairs growing, and those that do grow tend to be finer and slower. It’s just part of life, really.

Genetic and Hormonal Factors

Androgenetic alopecia – that’s the medical term for pattern baldness – is the most common reason for hair loss in both men and women. Essentially, if you’ve inherited a sensitivity to dihydrotestosterone (DHT), a testosterone derivative, your hair follicles gradually shrink over time. Research by Ustuner (2013) found that balding areas have higher levels of the enzyme that creates DHT, along with more DHT receptors.

What happens is this: DHT causes your follicles to progressively miniaturise, producing thinner, shorter hairs until they eventually stop producing hair altogether. Rather frustrating when you think about it.

For women, hormonal changes during pregnancy, after childbirth, or during menopause can trigger hair thinning too. Conditions like polycystic ovary syndrome can also cause either temporary or permanent changes to hair density.

Nutritional Factors and Deficiencies

Your hair needs proper fuel to grow – it’s one of the fastest-growing structures in your body, after all. If you’re following an unbalanced diet or trying crash diets, your hair often suffers first. We particularly see problems with deficiencies in:

• Iron (a well-known culprit in hair loss)
• Zinc (can lead to telogen effluvium and brittle hair)
• B vitamins (especially B12 and biotin)
• Protein
• Essential fatty acids

Guo & Katta’s 2017 research confirmed what we see in clinic every day – these nutritional gaps really do affect hair health.

Physical and Psychological Stress

Stress can literally shock your hair into shedding. When you’re under chronic stress, you might develop telogen effluvium – basically, loads of hairs suddenly decide to take a rest at the same time. Research by Asghar and colleagues (2020) shows just how powerful emotional and physical stress can be as triggers.

Here’s the thing: this type of hair loss typically shows up 2 to 3 months after whatever stressed you out – major surgery, illness, infection, or emotional trauma. You might find yourself losing up to 300 hairs daily during this time. The good news? It’s usually temporary.

Autoimmune and Inflammatory Conditions

Sometimes your immune system gets confused and attacks your hair follicles – that’s alopecia areata, which causes hair to fall out in distinct patches. Other conditions like lupus, dermatomyositis, or lichen planus can affect hair density too.

How Do You Know if Your Hair is Thinning?

Hair thinning can be quite sneaky – it doesn’t happen overnight. Here are the signs we tell our patients to watch for:

• A widening parting: Suddenly you’re noticing more scalp, especially in bright light
• More visible scalp: Your hair just doesn’t seem to cover as much as it used to, particularly at the crown
• Hair that feels different: When you run your fingers through it, there’s simply less there
• Loss of oomph: Your usual styles fall flat, and your hair just won’t hold its shape
• More shedding than usual: Finding more hairs on your brush, pillow, or after showering

If you’re concerned, a professional assessment can put your mind at ease. We might use trichoscopy (basically a special camera that lets us see your scalp in detail) or perform a traction test to check what’s really going on with your hair density.

How to Restore Hair Density

Right, let’s talk solutions – because there’s plenty you can do about thinning hair. First things first: you need a gentle yet effective hair care routine.

Choose shampoos and treatments with proper fortifying ingredients – biotin, keratin, or caffeine work particularly well to strengthen hair and encourage growth. And here’s a tip: regular scalp massage really does help by boosting circulation to your follicles. Just a few minutes whilst shampooing makes a difference.

Diet matters more than you might think. Remember those deficiencies we mentioned? A balanced diet helps, but sometimes supplements can give you that extra boost your hair needs.

As for treatments, there are some genuinely effective options. Minoxidil, for instance, helps extend your hair’s growth phase. Techniques like mesotherapy or microneedling can revitalise your scalp at a deeper level – we’ve seen some rather impressive results.

But equally important is what NOT to do. Avoid tight ponytails or man buns (yes, they can damage follicles), go easy on the heat styling, don’t brush too vigorously, and steer clear of harsh chemical treatments.

Here’s the thing though – results take time. You won’t wake up with a full head of hair next week, but with consistency and patience, you can absolutely see improvement.

Hair Transplant: A Permanent Solution for Hair Density

When hair thinning has progressed beyond what treatments can manage, or you simply want a more definitive solution, hair transplantation offers something rather special. It’s a permanent, natural-looking answer that’s become remarkably refined over the years.

Here’s how it works: we take healthy hair follicles from areas where your hair is still thick (usually the back and sides of your head) and carefully transplant them to the thinning areas. These transplanted follicles keep growing normally in their new location – brilliant, isn’t it?

We offer several techniques:

• FUE (Follicular Unit Extraction): We extract individual follicles one by one – no linear scar, minimal downtime
• DHI (Direct Hair Implantation): This allows us to implant grafts directly without making incisions first – particularly good for precision work

The science behind successful transplantation is fascinating. As Parsley & Perez-Meza (2010) noted, success hinges on keeping grafts hydrated, minimising handling trauma, and managing timing carefully. It’s precise work that requires genuine expertise.

Which technique suits you best? Well, that depends on several factors – the area needing treatment, your hair characteristics, and what you’re hoping to achieve. When performed by an experienced surgeon like Dr Cinik, the results look completely natural and harmonious with your existing hair.

Many of our patients tell us it’s not just about getting their hair back – it’s about feeling like themselves again. And that’s what makes this work so rewarding.
