Most people notice it gradually. A bit more on the pillow, a slightly wider parting, a moment under harsh bathroom lighting where you think, okay, something’s changing. Hair loss tends to sneak up on you, and by the time you taking it seriously, it’s already been happening for a while.
It affects roughly half of men by their fifties, and around a third of women also experience noticeable thinning at some point in their lives. It’s not often talked about openly, particularly among women, for whom the emotional weight of it tends to be heavier, which is why the numbers are higher than a lot of people think.
The Cause of Hair Loss Isn’t Always The Most Obvious
People often assume hair loss is purely genetic, and for a significant number of people, that’s true; androgenetic alopecia – the pattern baldness that runs in families – is the most common cause. However, there are plenty of other reasons hair starts to thin, and some can be fixable when you understand the why it’s happening.
Stress can trigger telogen effluvium, where a significant physical or emotional shock pushes a large number of your hair follicles into a resting phase simultaneously. You don’t see the shedding immediately; it tends to show up two or three months after whatever triggered it, which makes it genuinely confusing to pin down. People who had Covid-19 reported this in particularly high numbers, and the link is now reasonably well documented.
Thyroid problems, iron deficiency, changes in hormones after pregnancy or menopause, certain medications, and even crash dieting can all contribute. So before assuming you’ve inherited your dad’s hairline and that’s that, it’s actually worth getting some bloods done to rule things out. Some GPs are good about this. Others, honestly, less so.
The Treatments That Actually Have Evidence Behind Them
This is where it gets a bit more complicated, because the market for hair loss products is enormous and largely unregulated. You can spend a fortune on serums, supplements, and specialist shampoos that have little to no clinical backing, which is frustrating when there are treatments that genuinely do work for certain types of hair loss.
Minoxidil is probably the best-known option, originally developed as a blood pressure medication before its hair-growing side effects were noticed. It’s available over the counter in various forms and has a reasonable evidence base, though it works better for some people than others and you need to keep using it to maintain any results. Finasteride is another one, a prescription-only oral medication for men that blocks the hormone conversion largely responsible for male pattern baldness. It’s effective but does carry some potential side effects, which is why it needs a proper clinical conversation rather than just ordering it off the internet.
More recently, options like PRP therapy (where platelet-rich plasma from your own blood is injected into the scalp) and low-level laser therapy have gained traction, and the evidence is building, though it’s still not as solid as for the established medications. If you’re considering any of this, finding a reputable clinic rather than a pop-up aesthetic salon is genuinely important. Places like IQM Medical Limited offer proper hair loss treatment consultations with actual clinicians, which makes a difference when you’re trying to work out what’s appropriate for your specific situation.
When to Actually Do Something About It
The frustrating reality is that most treatments work better when you start them earlier. Hair follicles that have been dormant for years are harder to revive than those that have recently become inactive, so the “I’ll deal with it later” approach tends to close off options over time.
That doesn’t mean panicking the moment you find a few extra hairs in the shower, because some daily shedding is completely normal. But if you’re noticing consistent, sustained thinning over several months, or a visible change in density or your hairline, that’s probably the point to speak to someone rather than just hoping it stops on its own.
It’s not the most glamorous thing to bring up with a doctor, but it’s also not something you have to just accept without knowing your options first.
