Most people wait too long. Hair loss is noticed, attributed to stress or season, monitored anxiously for months, and only investigated once it’s clearly progressing.

That delay costs. Many causes of hair loss respond far better to early intervention, and some are entirely reversible if identified in time.

What Is a Trichologist?

Trichology is the study of hair and scalp health. A trichologist assesses the condition of the scalp and hair, identifies patterns of loss, and works out what’s driving them.

The distinction worth understanding: a trichologist is not a dermatologist. Where there’s a suspected medical condition — an autoimmune process, a thyroid disorder, a scalp disease — medical referral is appropriate and a good trichologist will make it.

Where trichology adds value is in the assessment itself, in identifying the pattern and probable cause, and in managing the substantial category of hair loss driven by scalp condition, nutrition, hormones and hair care practice rather than disease.

Common Causes of Hair Loss

Androgenetic (pattern) hair loss. The most common by a wide margin. Genetic, progressive, and affecting both men and women in different distributions. Earlier intervention produces better outcomes.

Telogen effluvium. Diffuse shedding triggered by a stressor — illness, surgery, childbirth, significant stress, rapid weight loss. The characteristic feature is timing: shedding typically begins two to three months after the trigger. Usually self-resolving, but the delay makes the cause hard to identify without asking the right questions.

Nutritional deficiency. Iron deficiency in particular, which is common and frequently undiagnosed in menstruating women. Vitamin D and zinc also feature. Blood work is the only way to establish this.

Thyroid dysfunction. Both under- and overactive thyroid affect hair. Requires medical diagnosis and treatment.

Hormonal changes. Postpartum, perimenopause, contraceptive changes, PCOS.

Traction alopecia. Mechanical damage from tight hairstyles sustained over time. Reversible early, permanent if left too long.

Scalp conditions. Seborrhoeic dermatitis, psoriasis and folliculitis all affect the environment hair grows in.

When to Book an Assessment

Sooner than most people do. Specific triggers:

• Noticeably more hair in the shower drain or brush, sustained over more than six weeks
• Visible widening of the parting
• A receding hairline or thinning at the crown
• Scalp becoming visible in normal light
• Any itching, flaking, redness or tenderness of the scalp
• Hair that feels different — finer, weaker, breaking

See a physician first if you have patchy or circular loss, sudden rapid loss, scalp pain or scarring, or accompanying symptoms like fatigue and weight change. These patterns suggest medical causes requiring diagnosis.

What a Consultation Involves

History. Family patterns, timing of onset, medical history, medications, recent stressors, diet, hair care practice. This is the most informative part and typically takes the longest.

Scalp and hair examination. Often with magnification, assessing scalp condition, follicle appearance, hair shaft quality and density distribution.

Pattern identification. Distinguishing diffuse from patterned loss, and shedding from breakage — these look similar to the person experiencing them and mean very different things.

Recommendations. Which may include medical referral, blood work, changes to hair care practice, or in-clinic treatment.

Treatment Approaches

Scalp mesotherapy. Microinjections delivering vitamins, amino acids and hyaluronic acid into the scalp, aimed at improving the environment follicles grow in. Delivered as a course over several months. Our general guide to mesotherapy covers the underlying method.

PRP. Platelet-rich plasma, prepared from a sample of your own blood and injected into the scalp. Used to support follicle function. Typically requires a course of sessions with maintenance thereafter.

Addressing scalp conditions. Where inflammation or dermatitis is present, resolving it is a prerequisite for anything else working.

Correcting deficiencies. If blood work identifies iron or vitamin D deficiency, addressing it is often the single most effective intervention.

Hair care changes. Reducing heat, tension and chemical processing. Unglamorous, and frequently the most useful advice.

What Results to Expect

Realistic expectations matter here more than in most areas.

Hair grows slowly. Roughly a centimetre a month. Any treatment aimed at improving growth takes months to show visible change — three at minimum, six to twelve for a fair assessment.

Improvement usually means slowing or stabilising loss and improving the quality of existing hair. Substantial regrowth in areas where follicles have been dormant for years is much less likely.

Consistency matters. Course-based treatments produce results when completed. Stopping partway generally means starting over.

Some causes resolve on their own. Telogen effluvium typically does. Knowing that saves money on treatment that wasn’t needed.

Anyone promising dramatic regrowth on a short timeline is overselling. The honest position is that early intervention protects what you have and improves what’s there.

Frequently Asked Questions

Is hair loss reversible? Depends entirely on cause. Telogen effluvium usually resolves. Nutritional causes respond to correction. Pattern loss can be slowed and managed but not reversed. Scarring alopecia is permanent.

Will I need to keep treating indefinitely? For ongoing causes like pattern loss, yes — maintenance is required to hold results. For resolved causes, no.

Can stress really cause hair loss? Yes, through telogen effluvium. The lag between stressor and shedding is what makes people doubt the connection.

Should I see a doctor or a trichologist first? If you have patchy loss, scalp pain, or systemic symptoms — a doctor. For gradual thinning or diffuse shedding, a trichology assessment is a reasonable starting point and will refer you onward if needed.
