Understanding Hair Loss

A plain-English guide from our doctor-led team — what causes hair loss, how it’s diagnosed, and the options worth knowing about before you decide anything.

The Basics

How hair actually grows

Every follicle on your scalp works through a repeating cycle: a long growth phase lasting a few years, a brief transition, then a short resting phase before the hair sheds and the follicle begins again. Because each follicle sits at a different point in that cycle, some shedding is completely normal — most people lose in the order of 50 to 100 hairs a day.

What’s worth paying attention to is a change: shedding that’s noticeably heavier or more sustained than usual, a receding hairline, or gradual thinning over months. Those are the signs it’s worth having your hair and scalp assessed rather than watching and waiting.

The Most Common Cause

Pattern (androgenetic) hair loss

The large majority of ongoing hair loss in both men and women is androgenetic alopecia — commonly called pattern hair loss. It’s driven by a combination of genetics and a hormone called DHT. In people who carry the relevant genes, affected follicles gradually become more sensitive to DHT, start producing finer “miniaturised” hairs, and eventually stop producing hair altogether.

The pattern differs between men and women. In men it usually begins at the temples or crown; in women it more often appears as diffuse thinning across the top of the scalp, while the frontal hairline is frequently preserved. Doctors describe these patterns using the Norwood scale for men and the Ludwig scale for women — a shared reference for assessing how far hair loss has progressed and planning what to do about it. You can read more on our guide to the Norwood scale.

Why It Works

The idea behind a transplant

Hair at the back and sides of the scalp is generally not affected by the genes that drive pattern hair loss — it tends to keep growing for life. That “donor” hair can be carefully relocated to thinning areas, where it continues to grow in its new position. This principle is what makes FUE hair restoration possible.

Whether a transplant is the right option — and how much donor hair is available to work with — is something we measure objectively rather than estimate by eye, using 3D TrichoLAB analysis.

It’s Not Always Pattern Loss

Other causes worth ruling out

Several other conditions can cause or contribute to hair loss — and they need different treatment, which is exactly why a proper diagnosis matters.

Telogen effluvium — temporary, heavier shedding often triggered by stress, illness, surgery, childbirth, rapid weight change or nutritional factors.
Thyroid and hormonal changes — an under- or over-active thyroid, and hormonal shifts such as those around pregnancy, can affect hair.
Alopecia areata — a likely autoimmune condition causing patchy hair loss.
Scarring alopecia — where inflammation or injury damages follicles; this needs medical assessment before anything else.
Nutritional and medication factors — iron and other deficiencies, or certain medications, can play a part.

Because the right treatment depends entirely on the real cause, guessing rarely helps. Some of these are temporary and settle once the trigger is addressed; others need managing before any hair-restoration option is considered.

Getting a proper diagnosis

An assessment with a doctor usually involves your medical history, a physical and scalp examination, and — where it helps — a closer look at the hair and scalp. In some cases an underlying issue (such as a thyroid condition or a deficiency) needs managing first, sometimes with your GP. For most people the cause turns out to be straightforward pattern hair loss, which is well understood and treatable.

At our clinic, the same doctor who assesses you also plans and performs your treatment. If you’d like to start, you can book an initial assessment or send photos for a free photo assessment.

Your Options

How hair loss is treated

Surgical — FUE hair restoration. Where suitable, follicles from the donor area are relocated to thinning areas one at a time. It’s a medical procedure with real benefits and real considerations — you can read about the process, risks and recovery on our FUE page.

Non-surgical & medical. Not everyone needs, or is ready for, surgery. The two hair-loss medications approved by the US FDA are minoxidil (topical) and finasteride (oral, prescription only); where clinically appropriate they can help slow loss or support regrowth, and are sometimes used alongside a transplant. Other approaches — such as PRP or low-level laser therapy — are also used, though the evidence for them varies. These are medical decisions: your doctor will talk through what’s suitable, and the benefits and risks, for you. Finasteride is generally not prescribed to women who are or may become pregnant. See our non-surgical & medical options.

The honest part. Individual results vary, and not everyone is a candidate for every option — sometimes the right answer is “not yet,” or a non-surgical path. The most useful first step is an honest, in-person conversation with a doctor who will assess your situation and give you a straight answer.
