Read this before making decisions about your hair.

The Hair Library is not a medical provider

We do not examine patients. We do not diagnose conditions. We do not perform procedures. We do not prescribe medications. Everything on this site is informational.

Rankings, ratings, and "match" recommendations are decision-support tools, not medical recommendations. A surgeon with in-person access to your scalp will always be better positioned than our algorithm.

Consult a licensed physician

Before starting any medication (finasteride, dutasteride, minoxidil, or others), undergoing any procedure (FUE, DHI, BHT, Sapphire, PRP, or others), or changing an existing treatment, consult a licensed medical doctor or qualified hair restoration surgeon in person.

Individual results vary

Patient journeys on The Hair Library are real, but they represent individual outcomes, not guaranteed results. Factors that affect your outcome include:

• Donor hair density and genetic pattern
• Age, overall health, and response to medication
• Stage of hair loss at the time of treatment
• Surgical technique and surgeon skill
• Post-operative care and lifestyle

A transplant that worked excellently for one patient may not produce the same density, timeline, or satisfaction for you. Always calibrate expectations with a qualified surgeon based on your specific scalp.

Medications have side effects

Finasteride, dutasteride, minoxidil, and other products covered on The Hair Library have documented side effects. We list these on each product page, but the list is not exhaustive and does not replace a conversation with your doctor. Sexual side effects, mood changes, cardiovascular considerations, and interactions with other medications are real concerns for some patients.

Emergency situations

The Hair Library is not equipped to handle medical emergencies. If you experience sudden bleeding, severe pain, signs of infection, or any other acute symptom after a procedure, contact your clinic or a hospital immediately. Do not use The Hair Library as an emergency channel.

Clinic responsibility

When you book a consultation or procedure through a clinic you found on The Hair Library, your medical care is the responsibility of that clinic and its licensed doctors — not The Hair Library. Any medical liability, malpractice claim, or clinical dispute is between you and the clinic directly.

Information currency

Medical evidence and clinical guidelines evolve. We try to keep content up-to-date and timestamp when entries were last reviewed, but we can't guarantee that any specific piece of information reflects the latest consensus. For the most current clinical guidance, consult a physician and recent peer-reviewed literature.

If you're researching at 2am

We know most people researching hair restoration do it late at night, privately, quietly. Use the information here as a starting point. Then sleep, compare what you read against what two or three qualified surgeons tell you in person, and take the decision slowly.

There's no time pressure. Hair restoration is almost never urgent. Good surgeons respect patients who ask a lot of questions.
