Noticing your hairline has changed is something that happens gradually and then, somehow, all at once. One morning you’re looking in the bathroom mirror under slightly harsher light than usual and it hits you; the crown looks thinner, the temples have crept back a bit, and suddenly you’re down a rabbit hole of Reddit threads and sponsored Instagram posts at 11pm, which is a terrible way to make any kind of health decision.
The honest truth is that hair loss is incredibly common, affects both men and women (though the patterns differ), and the options available now are considerably better than they were even a decade ago. That doesn’t mean every product on the market is worth your time or money, though. There’s a lot of noise around this topic, and separating the genuinely useful from the overpriced snake oil takes a bit of effort.
Why Hair Loss Happens in the First Place
Most hair loss in adults comes down to a condition called androgenetic alopecia, which is just the clinical way of saying pattern baldness. It’s hormonal, and it’s largely genetic, which means if your dad or your mum’s dad went thin early, you probably already know how this story goes. A hormone called DHT (dihydrotestosterone) essentially shrinks the hair follicles over time until they stop producing hair entirely. That process is more commonly noticed in your thirties and forties, but it can start in your 20s.
There are other causes too. Telogen effluvium, a type of hair shedding where the hair cycle is disrupted and causes you to lose than usual over a period of months, can be triggered by stress, nutritional deficiencies, thyroid problems, and certain medications, but this is often temporary. Hair is, annoyingly, one of the first things to reflect a body under pressure.
What Actually Works
Minoxidil has been around since the 1980s and is still one of the most studied, widely recommended options out there. It was originally developed as a blood pressure medication and hair regrowth was, essentially, an accident. You apply it directly to the scalp, usually twice a day, and it works by increasing blood flow to the follicles. It won’t bring back follicles that are completely gone, but for follicles that are just weakening, it can make a real difference. It takes time though. Most people need at least four to six months before they see meaningful results, and the gains stop if you stop using it.
Finasteride is the other main clinical option for men, and it works differently by actually blocking the conversion of testosterone to DHT. It’s prescription-only, which means you’ll need to speak to a doctor before starting it. If you’re thinking about exploring hair loss treatments through a medical provider, this is the kind of thing they’d assess you for, because it’s not right for everyone and does carry some potential side effects that are worth discussing properly rather than just ordering off some random website.
Low-level laser therapy has picked up a lot of interest in the last few years, with various devices marketed as home-use options. The evidence base is growing but still a bit patchy compared to minoxidil and finasteride. Not useless, but probably not your first port of call either.
The Stuff That Isn’t Worth the Price Tag
Biotin supplements are sold aggressively to people worried about hair loss. They do help if you have an actual biotin deficiency, which is rare. For the vast majority of people, taking extra biotin when your levels are already fine doesn’t do a great deal. Same goes for most “hair growth” shampoos, which tend to contain ingredients at concentrations too low to have much clinical effect. They’re not harmful, just a little optimistic.
Platelet-rich plasma therapy (PRP) is increasingly available in the UK, which involves drawing your own blood, processing it, and injecting the growth-factor-rich plasma into the scalp. The research is encouraging but still evolving, and it’s expensive, often £300 to £600 per session with multiple sessions needed.
Whatever route you’re considering, a conversation with an actual medical professional will save you time and money in the long run. Not every treatment suits every type of hair loss, and knowing what you’re actually dealing with makes all the difference before you spend anything significant on it.
