Find the Cause Before Choosing a Medicine
Pattern hair loss, telogen effluvium, alopecia areata, traction, iron deficiency, thyroid disease, inflammatory scalp disorders and medication-related shedding do not have one shared treatment. A product marketed for growth can delay useful investigation if the diagnosis is wrong.
The NHS advises seeing a GP to get an idea of the cause before approaching a commercial hair clinic. Seek medical advice for sudden or patchy loss, rapid change, scalp pain, redness, heavy scaling, scarring, eyebrow loss or symptoms of another illness.
A medication review includes health conditions, allergies, pregnancy potential, blood pressure, mood history, sexual side effects, other prescriptions and the patient’s priorities. This page is general information, not a dose or treatment plan.
Minoxidil for Pattern Hair Loss
Topical minoxidil is available in formulations applied to the scalp and can be used for some male and women’s pattern hair loss. It does not work for everybody, and benefit generally depends on continued use. Follow the product information or prescriber’s instructions rather than increasing the amount.
Possible problems include scalp irritation, dryness, unwanted hair growth outside the application area, dizziness, palpitations or changes related to blood pressure. Stop and seek appropriate advice for a significant reaction, chest pain, fainting, breathing difficulty or swelling.
Oral minoxidil is a different medical decision from a topical product. Its UK licensing and cardiovascular effects need discussion with a prescriber who can assess blood pressure, medical history and other medicines. Do not use somebody else’s tablets or convert a topical dose into an oral one.
Finasteride for Male Pattern Hair Loss
Finasteride 1 mg is indicated in the UK for male pattern hair loss in a defined patient group. It reduces conversion of testosterone to dihydrotestosterone. Response varies and any benefit generally depends on continued use.
The MHRA warns that finasteride has been associated with depressed mood, depression, suicidal thoughts and sexual dysfunction, and that sexual dysfunction has persisted after stopping in some reports. Patients should read the current leaflet and alert card, discuss a personal history of depression or suicidal thoughts before treatment, and report mood or sexual changes.
The MHRA finasteride and dutasteride safety update says people taking finasteride 1 mg for hair loss should stop immediately and contact their doctor as soon as possible if depression or suicidal thoughts develop. Anyone at immediate risk of self-harm needs urgent emergency or crisis support.
Dutasteride, Supplements and Other Products
Dutasteride may appear in online hair-loss advertising, but licensing, systemic effects and reproductive precautions differ from finasteride. The MHRA's May 2026 update also warns about psychiatric side effects and sexual dysfunction with dutasteride. Contact the prescriber as soon as possible if mood changes or sexual side effects develop. It should only be considered through an appropriately qualified prescriber who explains why it is being used and what monitoring applies.
Iron, vitamin D, zinc, biotin and other supplements are useful only in the right context. A suspected deficiency should be investigated. Excess supplementation can cause harm, interact with medicines or distort blood-test results; biotin is a known example of a supplement that can interfere with some laboratory tests.
Compounded topicals, combination sprays and online subscriptions still require clear ingredients, strength, prescriber details, pharmacy information, side-effect advice and a route for review. “Topical” does not mean there can be no systemic absorption.
Hair-Loss Medication for Women
The NHS states that minoxidil can be used for women’s pattern hair loss and that women should not use finasteride. Pregnancy, breastfeeding, fertility plans, hormonal symptoms and other medicines can materially change the options.
Women with diffuse thinning may need assessment for patterned loss, telogen effluvium, traction, nutritional deficiency, thyroid problems or an inflammatory condition. A widening parting is not enough to choose treatment without the rest of the history.
Read the Liverpool clinic’s guide to hair transplants for women. Surgery is only considered when the diagnosis and donor area support it.
Medication Before and After a Hair Transplant
A transplant moves follicles but does not stop native hair from changing. A prescriber may discuss treatment for suitable pattern loss before or after surgery, but it cannot be promised to preserve every native hair or prevent postoperative shaft shedding.
Give the surgical team a complete list of prescriptions, over-the-counter medicines, topical products and supplements. Some affect bleeding, blood pressure, anaesthetic planning or wound care. Do not stop a regular medicine without the advice of the clinician responsible for it.
The team should state when an existing topical can be used on healing recipient skin. Starting too early may irritate wounds; waiting longer may be appropriate for an individual operation. Written aftercare instructions take priority.
How Treatment Response Is Reviewed
Consistent photographs
Use similar lighting, camera angle, hair length, styling and dryness. A fibre product, wet scalp or different parting can change apparent density without a treatment effect.
Symptoms and side effects
Record changes in scalp comfort, shedding, mood, sexual function, blood pressure symptoms or unwanted hair. A treatment that changes a photograph is not acceptable if its adverse effects outweigh the benefit.
Review points depend on the medicine and diagnosis. Do not judge a long-term treatment after a few days, but do not wait for a planned photograph if a concerning reaction develops.
Where to Get Medical Advice
Read the NHS hair loss guide and speak to a GP, dermatologist, pharmacist or responsible prescriber about diagnosis and medicines. Use the Yellow Card scheme to report suspected side effects where appropriate.
Liverpool Hair Transplant Clinics can discuss how a current treatment fits with a proposed transplant, but urgent medical symptoms should use the appropriate NHS or emergency route.
