Trichological Hair Analysis: Finding the Cause of Hair Loss — Istanbul

Trichological hair analysis is a medical assessment of hair and scalp: history, examination, trichoscopy, a pull test and, when indicated, blood tests. It aims to identify the type of hair loss so treatment matches the cause. Veneta in Nişantaşı offers it; a physician plans any tests, supplements for proven deficiencies and treatment.

What Is Trichological Hair Analysis?

Hair loss has many causes, sometimes several at once. A physician asks when it began and about illnesses, childbirth, diets, medicines and hairstyles, then examines the scalp, nails and other affected areas.

Trichoscopy magnifies the scalp about 20–160 times: hairs of varying thickness suggest pattern hair loss, exclamation-mark hairs alopecia areata, and missing follicle openings scarring. In the pull test, about 40–60 hairs are tugged gently; more than 10% coming out suggests active shedding.

Blood Tests: What Is Checked and When

Test	Why	When
Ferritin, iron, blood count	Iron stores, anaemia	Diffuse shedding, especially in women
Thyroid (TSH)	Thyroid disease can cause shedding	Unexplained shedding, thyroid symptoms, alopecia areata
Vitamin D	Low levels linked to several types	Shedding, pattern hair loss, alopecia areata
Vitamin B12, folate	Not clearly linked to hair loss	Only if a deficiency is suspected
Zinc	Can be low in pattern loss and alopecia areata	Those conditions; not telogen effluvium
Testosterone, DHEAS (women)	Androgen excess	Irregular periods, excess facial or body hair

What the Analysis Can Find

Androgenetic alopecia (pattern hair loss): the most common type, usually inherited and gradual, in men and women.
Telogen effluvium: diffuse shedding 3–5 months after illness, childbirth, surgery or some medicines; it usually resolves within 2–6 months.
Alopecia areata: an autoimmune condition with round bald patches that often regrow; a dermatologist treats it.
Traction alopecia: caused by tight hairstyles; it can become permanent if the pulling continues.
Scarring alopecias, such as lichen planopilaris and frontal fibrosing alopecia: permanent loss that needs a dermatologist and, usually, a biopsy.

Who It Suits — and Who Should Wait

New shedding, thinning or patches, before supplements, PRP, medicines or a transplant.
Women with irregular periods or excess facial or body hair: hormone tests may be added.
A red, inflamed or scarred scalp, or smooth bald patches: see a dermatologist first.
Taking biotin? Say so before blood tests: the US FDA warns high doses can distort some lab results.
Pregnancy, or plans for one: finasteride and spironolactone are not used.

How the Analysis Works at Veneta

Assessment

A physician reviews your history, medicines, supplements and hair care.

Examination and trichoscopy

The scalp is examined, magnified and photographed; a pull test checks for active shedding.

Blood tests and diagnosis

Tests follow the findings; suspected scarring alopecia is referred to a dermatologist for a biopsy.

Aftercare and follow-up

You receive a written plan; progress is reviewed with repeat photographs and trichoscopy, as treatments take months.

From Diagnosis to Treatment

For pattern hair loss, topical minoxidil usually needs 6–12 months and works only while used; low-dose oral minoxidil is an off-label option, avoided in some heart conditions. Finasteride, for men, takes about 4 months; side effects include reduced libido. In 2025 the European Medicines Agency's safety committee confirmed suicidal thoughts as a side effect of finasteride tablets, of unknown frequency; patients with mood changes should seek medical advice and stop finasteride 1 mg. Spironolactone works in about 40% of women with pattern hair loss, says the American Academy of Dermatology (AAD).

PRP, usually given monthly for 3 months and then every 3–6 months, raised hair density in a 2024 meta-analysis, though the evidence was low-certainty. Hair mesotherapy rests on few small studies, with infections and scarring reported. Low-level laser therapy improved hair density in a few small studies but needs frequent sessions for months.

Supplements are used only for a proven deficiency. A hair transplant needs stable, patterned loss and enough donor hair; scarring alopecia should first be in remission for at least 1–2 years.

Frequently Asked Questions

What does a trichological hair analysis include?

A trichological hair analysis combines history, a scalp examination, trichoscopy, a pull test and photographs, plus blood tests when the findings suggest a cause.

Which blood tests are needed for hair loss?

In a trichological hair analysis, tests follow the findings: ferritin and vitamin D in diffuse shedding, zinc in pattern hair loss, thyroid or hormone tests for matching symptoms, and B12 or folate only if a deficiency is suspected.

Is my hair loss temporary?

Whether hair loss is temporary depends on the cause a trichological hair analysis finds: telogen effluvium usually resolves within 2–6 months, pattern hair loss tends to progress, and scarring alopecia is permanent.

Should I take biotin for hair loss?

Take biotin only for a deficiency found in a trichological hair analysis. The American Academy of Dermatology warns that unneeded supplements can be harmful, and the US FDA that high-dose biotin can distort some lab results.

Do PRP, mesotherapy or laser therapy work for hair loss?

For pattern hair loss found in a trichological hair analysis, PRP raised hair density in meta-analyses, with low-certainty evidence; evidence for laser therapy and mesotherapy is limited.

Am I a candidate for a hair transplant?

A trichological hair analysis checks for stable, patterned loss and enough donor hair. Diffuse thinning rarely suits a hair transplant, and scarring alopecia should first be in remission for at least 1–2 years.
