@zararaye_'s hair growth claims need more context

What did @zararaye_ actually say?

Honestly, not much we can work with. The transcript captured from this video is almost entirely filler: "Yeah. Alright. Alright. Alright. Alright. Okay. So You" — and then nothing. That's it. Whatever @zararaye_ was documenting about a five-month hair growth journey, the words didn't make it into the transcript we have to work with.

The video is categorized under peptide therapy, and the hashtags point clearly to a hair transformation narrative. So the implied claim is that something, probably a peptide or peptide-adjacent protocol, drove meaningful hair growth over five months. But we can't quote the creator on specifics because the transcript doesn't give us any.

We're going to assess the broader category of claims this kind of video typically makes, and what the evidence actually says about peptides and hair growth.

Does the science back up peptides for hair growth?

The short answer: it depends heavily on which peptide you're talking about, and the human evidence is thinner than most TikTok content implies. GHK-Cu (copper peptide) has the most studied track record for hair, and even that evidence has significant limits.

A 1993 study by Uno and colleagues, published in Skin Pharmacology, found GHK-Cu stimulated hair follicle enlargement in a scalp organ culture model. More recently, a 2018 paper in the Journal of Cosmetic Dermatology by Gorouhi and Maibach reviewed copper peptides in skin and hair, noting promising preclinical findings but calling the clinical data "insufficient for definitive conclusions." That's the honest read.

BPC-157, another peptide popular in this space, has shown angiogenic effects in animal studies, which theoretically could support follicle health through improved blood supply. But published human trials on BPC-157 for hair specifically? They don't exist yet. MK-677 raises IGF-1 levels, and IGF-1 does play a role in the anabolic phase of hair cycling, but the jump from "raises IGF-1" to "grows your hair back" involves several assumptions the data doesn't yet support.

What did they get wrong, or right?

We can't credit or correct @zararaye_ on specifics without a real transcript. What we can say is that five-month before-and-after hair videos, regardless of what protocol they're using, routinely confuse correlation with causation.

Hair grows roughly half an inch per month on average, so five months of normal growth already produces visible change. Shedding cycles also mean that someone who stops a stressor, corrects a nutritional deficiency, or simply reduces inflammation might see a rebound that looks dramatic on video but isn't a peptide effect at all.

If the creator is attributing their results to a specific peptide stack without controlling for diet, stress, sleep, or whether they previously had a deficiency, that's a methodological problem. One person's five-month journey is not a clinical trial. It's an anecdote, and anecdotes mislead people into spending money on compounds that haven't been proven safe or effective for this use in humans.

What should you actually know?

If you're curious about peptides and hair growth, here's what the evidence actually supports right now. GHK-Cu applied topically has the most backing for scalp use, though the studies are small. Systemic peptide use for hair, meaning injections or oral peptides like MK-677, operates largely on mechanistic plausibility rather than proven outcomes in humans.

Hair loss has well-established, FDA-approved treatments: minoxidil and finasteride for androgenetic alopecia, with solid trial data behind them. Before chasing a peptide protocol based on a TikTok transformation video, it's worth asking whether a basic workup has been done: ferritin, thyroid function, androgens, vitamin D. Many dramatic hair "recoveries" documented online are simply the resolution of a correctable deficiency.

A telehealth provider can help you figure out whether peptides are even appropriate for your specific situation, what compounds have any real evidence behind them, and how to think about safety given that most peptides for this use are off-label and unregulated for hair indications specifically.
