Every GLP-1 Weight Loss Drug, Ranked (2026)
Tirzepatide and retatrutide lead every GLP-1 weight loss drug on weight lost beyond placebo, with semaglutide, CagriSema, MariTide, mazdutide and amycretin close behind. The "natural GLP-1" supplements at the bottom contain no GLP-1 drug at all. Here is each drug, the trial behind its ranking, and what the side effects change.
Why Hair Transplants Are Not a Cure: The Body Sets the Organ's Age
A new Harvard preprint found that transplanted hearts take on the biological age of the body they are placed in, and no recipient got younger. Hair follicles follow part of the same rule: moved follicles take on some traits of their new site, the recipient site can override a graft entirely, and the native hair around a transplant keeps thinning because the transplant does not change the scalp.
Immediate Release vs. Extended Release Minoxidil: Why the Peak Matters
Short answer: An immediate release tablet delivers an entire dose as one early spike. Extended release tablets spread the same dose into a lower, longer curve. This strategy can be especially useful for drugs that cause side effects over a certain dose, but have a positive clinical effect at a much lower dose. Minoxidil has been found to have both, a safety threshold where hemodynamic effects are felt and an efficacy threshold at which hair growth takes place.
MINX Tolerability: Side Effects in Our First 20 Users vs 5 mg Oral Minoxidil
What our first 20 MINX 5 mg users reported about side effects, compared head-to-head with the published 5 mg oral minoxidil study and against low-dose oral minoxidil across 1,404 patients. A consumer perception study, not a clinical trial.
Smooth Release vs. Extended Release Minoxidil: What's the Difference?
Short answer: "extended release" is a broad pharmaceutical category. "Smooth release" is our name for the specific curve MINX is aiming for: to get rid of Minoxidil's large peak. Some people already try to flatten the curve by splitting immediate-release oral minoxidil across the day. MINX approaches the problem through a lipid-matrix formulation compounded per prescription under 503A. This post shows our measured and modeled PK, along with what the two-subject pilot can't tell us, including how MINX compares with split dosing.
Zero Order vs. First Order Release: The Six Shapes Behind Extended-Release Drugs
Short answer: "extended release" does not name a curve. It names many. An extended-release product can release a fixed amount per hour, slow down as it empties, pulse twice, wait until it reaches the intestine, or deliberately speed up over time. Each shape solves a different problem. Which one an extended-release formulation follows is derived from its dissolution and pharmacokinetic data. We delve into the most sought-after release profiles below.12 Hair Supplement Ingredients Backed by Human Studies: What Actually Works for Growth and Greying
Which hair supplement ingredients actually work? A study-by-study breakdown of pumpkin seed oil, saw palmetto, L-cystine, tocotrienols, and the vitamins linked to premature greying, with doses and cited sources.
AMP-303 (Amplifica): What the Phase 1 Hair Loss Data Actually Shows
Amplifica raised $26 million with Eli Lilly participating, and AMP-303 is being called the hairy mole drug. Its own patent says the study compound is 0.3% hyaluronic acid. Here is what the Phase 1 data shows, what it leaves out, and why the molecular weight matters.
Which Countries Have the Most Bald Men? The Baldness Map Is Really an Ancestry Map
Spain tops the world baldness rankings at 44.5%, but the real story is ancestry: clinical studies find a roughly threefold gap between European and East Asian men.
Is Scalp DHT Really Maxed Out on Finasteride, or Can You Push It Lower?
Standard finasteride clears most serum DHT but far less scalp DHT. Here is what the head-to-head trials actually show about how low scalp DHT can really go.
The 8 Experiments That Would Settle How Minoxidil Actually Works
Minoxidil response was never one number. It is a balance of five things and the field measures one. Here are the eight experiments that would measure the rest, and what each one would finally answer.
What Changes in a Balding Scalp, Gene by Gene
Every gene expression difference between balding and non-balding scalp that replicates across independent studies, and which famous findings do not survive scrutiny.
What We Still Do Not Know About Minoxidil: 9 Open Questions in the Science
Minoxidil is the most-used hair drug in the world, yet the foundational experiments were skipped. No one has measured its active form in blood, seen its enzyme in a human follicle, or tested whether the scalp deactivates it as fast as it turns it on.
Minoxidil Once a Day vs Twice a Day: Where the Absorption Ceiling Actually Sits
Topical minoxidil absorption does saturate, but the ceiling sits around four applications a day. Below that, in the range people actually use, more frequent application still increased the amount absorbed.
What DHT Actually Does Downstream, and Why Targeting Below the Hormone Matters
DHT does not shrink a follicle by touching the hair. It flips a switch inside dermal papilla cells, which then release inhibitory signals like DKK-1, TGF-beta, and IL-6.
Which Genes Predict Minoxidil Response? Every Gene Ranked by Actual Evidence
If you have whole genome data, here is every gene that could predict whether minoxidil works for you, ranked by evidence, and why the variant nearly every genetic test reports ranks last.
The Third 5-Alpha-Reductase Is a Misnomer: SRD5A3 Does Not Lower DHT
People say there are three 5-alpha-reductases. Only two make DHT. The third, SRD5A3, is really a polyprenol reductase in the sugar-coating pathway.
Are Finasteride and Dutasteride Irreversible? What That Actually Means
Finasteride and dutasteride are both irreversible 5-alpha-reductase inhibitors, but that describes their grip on one enzyme molecule, not a permanent change to your body. Three clocks explain the difference.
One Enzyme, Three Jobs: Everything 5-Alpha-Reductase Makes
5-alpha-reductase is not just the DHT enzyme. It runs three steroid lanes: androgens for hair, calming neurosteroids, and cortisol cleanup.
How Minoxidil Actually Works: The Real Mechanism Behind Hair Growth
Minoxidil does not grow hair by boosting blood flow. It opens one potassium channel in the follicle and sets off a rejuvenation cascade, a story told by just five human-follicle studies across 31 years.
SULT1A1: Why Minoxidil Works for Some People and Not Others
Topical minoxidil is a prodrug that your scalp has to switch on with an enzyme called SULT1A1. How much you have is one of the best predictors of whether topical minoxidil grows your hair, and why oral often works when topical hasn't.
What Blocks SULT1A1? The Everyday Drugs and Supplements Competing With Your Minoxidil
Minoxidil is a prodrug switched on by the enzyme SULT1A1. Birth control, green tea, turmeric, quercetin, and Tylenol all compete for that enzyme, but almost none of it has been tested on a real human scalp.
Does BPC-157 Grow Hair? The Evidence, and the Study That Does Not Exist
PubMed indexes 222 BPC-157 papers and not one is about hair. The claim traces to a 2001 experiment that burned mice, and the trial clinics cite for scalp injections cannot be found in any database.
Do Corticosteroids Regrow Hair? What the Evidence Actually Shows
No corticosteroid regrows pattern hair, and hydrocortisone has no regrowth evidence anywhere. Steroids only help by calming the immune attack in alopecia areata or the inflammation in scarring alopecia.
How Does Minoxidil Work? It Is the Potassium Channel, Not Blood Flow
Minoxidil does not grow hair by increasing blood flow. It opens ATP-sensitive potassium channels, the same mechanism behind diazoxide and pinacidil. Here is how minoxidil actually works.
Does Minoxidil Affect DHT? Every Study, and What They Actually Show
No human study shows minoxidil lowers DHT, and the lab studies contradict each other. Here is every study on whether minoxidil is a DHT blocker, and why it does not matter.
Bimatoprost vs Latanoprost for Hair Loss: What the Preclinical and Clinical Data Actually Show
Bimatoprost (Latisse) is FDA-approved to grow eyelashes, and latanoprost grows them too. But do these prostaglandin analogs regrow scalp hair? A full look at every preclinical and clinical study for both drugs, and the wider prostaglandin class.
Do You Inherit Baldness From Your Mother or Father? The Genetics of Male Pattern Baldness
Does baldness come from your mother's side, or your mother's father? The maternal-grandfather rule is only half right. We ranked the genes by strength and modeled the split: about 56 percent of your baldness risk traces to your mother and 44 percent to your father.
Is Your Hair Controlled by a Clock? The Circadian Biology of the Hair Follicle
Every hair follicle runs its own 24-hour clock, set by your sleep cycle. Here is what that clock actually does, what the genes control, and what the evidence does not support.
Minoxidil Dose-Response: Why More Hair Eventually Stops but the Side Effects Don't
Across low-dose oral minoxidil studies, each +1 mg grows about 9 more terminal hairs/cm² but also raises hypertrichosis and cardiac side effects. Then the growth curve bends while the risks keep climbing.
Does Ozempic Cause Hair Loss?
GLP-1 weight-loss drugs like Ozempic, Wegovy, Mounjaro, and Zepbound carry a real hair-loss signal, but the cause is mostly telogen effluvium from rapid weight loss, not the drug attacking your follicles. The verified rates, the mechanism, why women see it more, and what actually helps.
Finasteride vs. Dutasteride for Hair Loss: A Research-Backed Comparison of Effectiveness, Side Effects & Best Use Cases
Finasteride blocks one DHT-making enzyme; dutasteride blocks both. We break down the history, the binding affinities, the scalp enzyme map, head-to-head efficacy, and the lowest and standard doses of each. Educational only, not medical advice.
Sublingual Minoxidil: The Most Overhyped Product in Hair Care
Sublingual minoxidil is sold as the smooth-release, safer alternative to standard oral. The published pharmacokinetics say it is neither: at 5 mg it has the same peak timing as standard oral and roughly 3x the peak of MINX at the same dose. Here are the three PK tests a real prolonged-release oral minoxidil has to pass, and where each route actually lands.

Hair Loss and Thyroid: The Complete Guide to Hypothyroidism and Hair Loss
Hair loss affects 30% of people with thyroid issues, yet it's often undiagnosed. Thyroid hormones (especially T3) directly control hair follicle growth cycles. Unlike pattern baldness, thyroid hair loss causes diffuse thinning across the entire scalp. With proper diagnosis and treatment including thyroid hormone optimization, 70-80% of patients see significant regrowth within 6-12 months. Early intervention is key.
