Do steroids actually cause hair loss, or is it more complicated?

What did @pinwithben actually say?

The core claim is straightforward: anabolic steroids raise testosterone, which converts to DHT, and DHT shrinks hair follicles. But whether you actually lose hair depends entirely on your genetics. "If your hair is already resistant to that, you will most likely not lose your hair even being on gear." For guys who are already prone to male pattern baldness, steroids "just basically fast track their hair loss." He's framing this as a myth-bust, arguing it's not steroids causing hair loss, it's your genetic lottery ticket.

To his credit, he's not selling anything here and he's not telling people to blast without consequence. The framing is relatively honest about risk. But the genetics-only explanation leaves out some important mechanics that matter a lot for real-world outcomes.

Does the science back this up?

Mostly, yes. The DHT pathway he describes is well-established. Androgenetic alopecia (male pattern baldness) is driven by DHT binding to androgen receptors in genetically sensitive follicles, causing progressive miniaturization. Randall et al. (1992, Journal of Endocrinology) were among the first to clearly map this receptor-driven process. The genetic component is real and significant.

The 5-alpha reductase enzyme converts testosterone to DHT, and supraphysiologic testosterone doses, which is what "blasting" means, dramatically increase the substrate available for that conversion. A 2021 review by Kinter and Schmidt in StatPearls confirms that androgenetic alopecia requires both genetic predisposition and androgen exposure. So the genetics story is not wrong. It's just incomplete in ways that matter when someone is deciding whether to run a cycle.

One thing the science is less settled on: the claim that someone with "good hair genetics" will "most likely not lose hair" on gear. That's plausible but not guaranteed. High enough androgen load can push borderline cases over the edge, and some steroids, particularly DHT derivatives like trenbolone or Masteron, are more aggressive on follicles than testosterone alone.

What did they get wrong (or right)?

He got the basic mechanism right. DHT, follicle sensitivity, genetic predisposition, that's the actual biology. Give credit where it's due.

What he glossed over is that not all anabolics are equal in terms of hair impact. He talks about "gear" as a monolithic category, but that's not how it works. Nandrolone (Deca) converts to a weaker androgen, dihydronandrolone, and is considered relatively hair-friendly. By contrast, DHT-derived compounds like stanozolol or Masteron don't need to convert at all because they're already potent androgens that bind directly to follicle receptors. Rassman and Bernstein (2017, International Journal of Trichology) have written about how the compound choice, not just the presence of androgens, affects hair outcomes.

He also presents genetics as binary: you're either prone or you're not. In reality, androgenetic alopecia exists on a spectrum. Someone who might have lost hair at 55 could find themselves losing it at 27 on a blast cycle. That's not splitting hairs, it's a meaningful distinction for a 23-year-old watching this video.

What should you actually know?

If you're considering exogenous testosterone or anabolics and you care about your hair, here's what the evidence actually supports:

• Your family history matters, but it's not a guarantee either way. Having a full-haired grandfather doesn't make you immune to DHT-driven follicle damage at supraphysiologic androgen levels.
• The specific compound matters. Not all steroids carry the same hair risk. DHT-derived compounds carry higher risk than testosterone-based ones, which carry higher risk than nandrolone-based ones.
• Dose and duration matter. A physiologic TRT dose (bringing someone from clinically low testosterone to normal range) carries far less hair risk than a blast protocol designed to push testosterone several times above the normal range.
• Finasteride, a 5-alpha reductase inhibitor, blocks DHT conversion and is used to mitigate hair loss in this context, but it comes with its own side effect profile and is a prescription medication. It's not a free pass.
• Hair loss from androgen exposure can be permanent if follicles are fully miniaturized. Slowing down a process is not the same as stopping it.

The video is useful as a starting point, but anyone making decisions about anabolics based on a 90-second TikTok is working with an incomplete picture.
