Trichologist: what they do, what they treat and when to see a hair and scalp specialist

A trichologist is a specialist in hair and scalp health. In clinical practice, trichology focuses on assessing hair loss, changes in hair density, scalp symptoms and disorders that affect the hair follicle or the skin of the scalp.

However, it is important to clarify one point from the beginning: in the UK, the word trichologist does not always mean medical doctor. Some trichologists are trained hair and scalp specialists, while others may also have medical qualifications. At Face Clinic, hair loss and scalp concerns are assessed from a medical perspective, especially when there may be underlying causes or when treatments such as medication, regenerative procedures or hair transplantation need to be considered.

Patients often ask what the “doctor for hair” is called, or which specialist they should see when they notice hair shedding, thinning, scalp itching, flaking, pain, inflammation or a visible change in hair quality. In many cases, a hair and scalp specialist or a doctor with experience in trichology is the right first step for a structured diagnosis.

Medical diagnosis should come before any hair loss treatment. The aim of a trichology consultation is to understand why the hair is falling before deciding whether the patient needs medical treatment, nutritional assessment, regenerative procedures or hair transplant planning.

What is a trichologist?

A trichologist is a specialist who focuses on the hair and scalp. The term comes from trichology, the field that studies the structure, growth, function and disorders of human hair and the scalp.

In everyday language, patients may describe a trichologist as a “hair specialist”, “scalp specialist” or “hair loss specialist”. From a clinical point of view, the most important issue is not the title alone, but whether the professional can assess the patient properly, identify possible causes of hair loss and refer or treat appropriately depending on the diagnosis.

At Face Clinic, the trichology consultation is especially important before starting any hair treatment and, in particular, before considering a hair transplant in Spain. A hair transplant should not be planned only because the patient has visible hair loss; it should be based on diagnosis, donor area assessment, hair loss stability and realistic expectations.

What is trichology?

Trichology is the study of the hair and scalp. It looks at the hair growth cycle, the condition of the scalp, the behaviour of the hair follicle and the different disorders that may affect hair density, shedding or quality.

In a medical setting, trichology helps distinguish between different forms of hair loss, such as androgenetic alopecia, telogen effluvium, alopecia areata, scarring alopecia or scalp inflammation. This distinction is essential because the treatment approach is not the same for each condition.

For example, temporary shedding after stress, illness, childbirth, nutritional deficiency or hormonal change is very different from progressive pattern hair loss. NHS Inform describes telogen effluvium as increased hair shedding that can be triggered by illness, stress, nutritional deficiencies, childbirth or endocrine disorders such as thyroid disease.

What does a trichologist do?

A trichologist or medical hair specialist assesses the hair and scalp to understand why a patient is losing hair or experiencing symptoms such as itching, flaking, pain, oiliness, inflammation or breakage.

The role may include:

• assessing the pattern and severity of hair loss,
• examining the scalp and hair shaft,
• identifying possible inflammatory or dermatological conditions,
• detecting signs of diffuse shedding or progressive thinning,
• reviewing medical history, medication, stress, nutrition and hormonal factors,
• requesting or recommending complementary tests when needed,
• advising on medical, aesthetic or surgical treatment options,
• determining whether the patient may be a candidate for a hair transplant,
• monitoring response to treatment over time.

Hair loss can have many causes, and the NHS recommends seeking medical advice if you are worried about hair loss, especially before going to a commercial hair clinic. This is why an accurate diagnosis should come before any treatment decision.

What conditions can a trichologist assess?

A trichology consultation may be useful for several types of hair and scalp problems. Some are temporary and reversible, while others require long-term monitoring or medical treatment.

Androgenetic alopecia

Androgenetic alopecia, also known as pattern hair loss, is one of the most common reasons for consultation. In men, it often appears as recession at the temples, thinning on the crown or a progressive change in the frontal hairline. In women, it more commonly presents as diffuse thinning over the central scalp, although patterns can vary.

Female hair loss

Female hair loss requires careful assessment because several factors may be involved, including genetics, hormonal changes, iron deficiency, thyroid dysfunction, stress, medication or inflammatory scalp disease. The British Association of Dermatologists has specific patient information on female pattern hair loss and highlights the importance of diagnosis and treatment planning.

Telogen effluvium

Telogen effluvium is a type of diffuse shedding that often appears after a trigger such as illness, stress, childbirth, nutritional deficiency, surgery or endocrine changes. Patients usually notice increased hair fall rather than a clearly defined bald patch.

Alopecia areata

Alopecia areata is a non-scarring type of hair loss that may appear as round or oval patches. According to the British Association of Dermatologists, alopecia areata can occur at any age and is usually classified as non-scarring hair loss.

Scarring alopecia

Scarring alopecias are conditions in which inflammation can damage the hair follicle permanently. They require prompt assessment because early diagnosis may help preserve remaining hair. These cases should be managed medically and may require specialist dermatological or surgical input.

Scalp inflammation, itching or flaking

Some patients attend a trichology consultation because of scalp symptoms rather than visible hair loss. Persistent itching, scaling, redness, pain, burning or excessive oiliness may be linked to conditions such as seborrhoeic dermatitis, psoriasis, folliculitis or other inflammatory disorders.

Hair breakage and changes in hair quality

Hair breakage, brittle hair or a sudden change in hair texture can be related to hair care practices, nutritional factors, hormonal changes, chemical treatments, heat damage or systemic health issues. A structured assessment helps determine whether the problem is cosmetic, medical or mixed.

What is a trichogram?

A trichogram is a diagnostic test used to analyse the hair and assess the proportion of hairs in different growth phases. It can provide information about the hair cycle, shedding pattern and follicular activity.

In clinical practice, a trichogram may help distinguish between different types of alopecia or shedding. It is not the only diagnostic tool, but it can be useful when combined with medical history, scalp examination, trichoscopy and, when appropriate, blood tests or other investigations.

What to expect during a trichology consultation

A trichology consultation should not consist only of looking at the hair and recommending a product. A proper assessment usually includes a structured medical and hair history, scalp examination and a review of possible triggers.

1. Medical and hair history

The specialist will ask when the hair loss started, whether it is sudden or progressive, whether there is shedding or thinning, whether the scalp is symptomatic and whether there are relevant medical conditions, medication, recent illness, stress, childbirth or hormonal changes.

2. Scalp and hair examination

The scalp is examined to assess inflammation, flaking, redness, follicular openings, hair density and distribution of thinning. The pattern of hair loss is often one of the most important clues in diagnosis.

3. Diagnostic tests when needed

Depending on the case, the doctor may recommend a trichogram, trichoscopy, blood tests or further medical assessment. Possible blood tests may include iron status, thyroid function, vitamin levels or hormonal studies when clinically indicated.

4. Treatment planning

Once the likely cause has been identified, the treatment plan may include medical treatment, topical or oral medication, lifestyle measures, scalp care, nutritional support, regenerative procedures, follow-up or surgical planning in selected patients.

When should you see a trichologist?

You should consider seeing a trichologist, hair loss doctor or hair and scalp specialist if you notice:

• sudden or excessive hair shedding,
• progressive thinning or reduced density,
• receding hairline or crown thinning,
• patches of hair loss,
• persistent scalp itching, flaking, pain or inflammation,
• hair breakage or visible change in hair quality,
• hair loss after illness, stress, childbirth or medication,
• poor response to previous hair treatments,
• uncertainty about whether you are a candidate for a hair transplant.

In adults, it is common to seek help late, when hair loss is already visible. Earlier assessment can help identify the cause, avoid inappropriate treatments and establish realistic expectations.

Is a trichologist the same as a dermatologist?

Not always. A dermatologist is a medical doctor specialised in diseases of the skin, hair and nails. A trichologist is a specialist in hair and scalp problems, but in the UK the term does not automatically mean that the person is medically qualified.

This distinction matters because some hair loss conditions may require medical diagnosis, prescription treatment, blood tests, biopsy or referral to another specialist. In medically complex cases, a doctor with experience in hair disorders or a dermatologist may be necessary.

For patients, the practical question is: does the professional have the right clinical training and pathway to assess, treat or refer the case safely?

Can nutrition affect hair loss?

Nutrition can play a role in some types of hair shedding, especially when there are deficiencies or restrictive diets. Iron deficiency, low protein intake, sudden weight loss or certain metabolic conditions may contribute to hair changes in selected patients.

This does not mean that every case of hair loss is caused by diet. However, when the history suggests nutritional involvement, it may be appropriate to assess dietary factors and, if needed, involve a nutritionist as part of a wider medical plan.

Trichology and hair transplant planning

A trichology consultation is especially useful before considering hair transplantation. Not every patient with hair loss is immediately suitable for surgery. The diagnosis, donor area quality, age, hair loss stability, expectations and future progression all need to be assessed.

In some patients, medical treatment may be recommended before surgery to stabilise hair loss. In others, a transplant may be appropriate, but only after careful planning of the hairline, donor area and long-term strategy.

Patients who are comparing options often ask about the cost for hair transplant. The answer depends on the number of grafts, donor area, degree of hair loss, technique, surgical planning and whether additional treatments are needed before or after the procedure.
