Trichologist or dermatologist: who should I see?
If you are worried about your hair or scalp, it can be hard to know who to turn to. Trichologists and dermatologists both work with hair and scalp problems, but their training, their role and the way you reach them are quite different. This guide sets out the differences so you can choose a sensible first step.
Clinical review by a named practitioner is in progress.
The short answer
If your hair loss is sudden, patchy, painful or inflamed, if it affects a child, or if you feel unwell in other ways, start with your GP. They can refer you to a dermatologist, who is a medical doctor.
If your concern is more gradual, such as general thinning, breakage, flaking or a scalp that never feels quite right, a trichologist can be a helpful place to start. A good trichologist will tell you if you need to see a doctor.
What a dermatologist is
A dermatologist is a qualified medical doctor who has completed specialist training in conditions of the skin, hair and nails. Because hair grows from the skin, hair loss and scalp disease are part of their work.
Dermatologists can diagnose conditions, order blood tests, take a small scalp biopsy when needed and prescribe medicines. In Ireland and the UK you usually see one after a referral from your GP, either through the HSE or the NHS, or privately. Public waiting lists can be long, so it is worth seeing your GP early.
What a trichologist is
A trichologist specialises in the health of the hair and scalp. They take a detailed history, examine the scalp and hair, often with magnification, and give advice on care, lifestyle and treatments within their scope.
Most trichologists are not medical doctors, so they cannot prescribe medicines or make a formal medical diagnosis. Trichology is also not a statutorily regulated profession in Ireland or the UK, which means anyone can use the title. It is sensible to ask about a trichologist's training and whether they belong to a recognised professional body with a code of conduct.
Signs you should see a doctor first
Some changes need a medical assessment rather than cosmetic or trichology care alone. See your GP if you notice any of the following:
- Sudden patchy hair loss, or smooth round bald patches.
- Pain, burning, marked redness, pus or open sores on the scalp.
- Scalp that looks shiny, scarred or has lost visible follicles.
- Loss of eyebrows or eyelashes.
- Rapid hair loss over a few weeks.
- Hair loss with other symptoms such as fatigue, feeling cold, weight change or irregular periods.
- Any hair loss in a child.
Your GP is also the right person to arrange blood tests, such as iron stores and thyroid function, which are often useful when hair is shedding.
How the two can work together
Trichologists and dermatologists are not rivals. Many people see both at different points. A dermatologist might diagnose and treat a condition, while a trichologist helps with day-to-day scalp care, styling habits and monitoring changes over time.
Other professionals can play a part too. A hairdresser or head spa therapist is often the first to notice a change on the scalp, and a nurse or doctor with an interest in hair may offer specific treatments in a clinic setting.
Preparing for either appointment
Whoever you see, a little preparation makes the appointment more useful. Write down when you first noticed the change, how quickly it has progressed and anything significant that happened in the months before, such as an illness, a new medicine, a pregnancy or a stressful period. Bring a list of your medicines and supplements, and any recent blood test results.
Photographs can help too. Pictures of your hair from a year or two ago, and a few taken now in good light from the same angles, make it easier to show what has changed. It is also worth noting the products you use and how you usually style your hair.
Finding the right person
Trichollective's directory lists cosmetic, clinical and medical hair and scalp professionals across Ireland and the UK, so you can see who works near you and what kind of care they offer. Our short guided tool can also suggest which type of professional might suit your concern. It does not diagnose, and it is not a substitute for seeing your GP.
Common questions
Do I need a referral to see a dermatologist?
Usually, yes. In Ireland and the UK, public dermatology appointments through the HSE or the NHS need a GP referral, and many private dermatologists also ask for one. Your GP can do an initial assessment, arrange blood tests and decide how urgent the referral should be.
Is a trichologist a doctor?
Most trichologists are not medical doctors. They specialise in hair and scalp health and can assess and advise, but they cannot prescribe medicines or make a medical diagnosis. Trichology is not statutorily regulated in Ireland or the UK, so check a practitioner's training and professional body membership.
Can a trichologist help with hair loss?
A trichologist can assess your hair and scalp, look at your history and lifestyle, suggest care and treatments within their scope, and track changes over time. They should refer you to your GP when signs point to a medical cause, such as sudden patchy loss, scarring or symptoms elsewhere in the body.
Should I see my GP before a trichologist?
If your hair loss is sudden, patchy, painful or inflamed, affects a child, or comes with other symptoms such as tiredness or weight change, see your GP first. For slower changes, a trichologist can be a reasonable first step, provided they refer you to a doctor when needed.
