Minoxidil-Free, Biotin-Free, Prostaglandin-Free: The Let It Thrive Philosophy

TL;DR: Three ingredients dominate the hair, lash and brow aisle — prostaglandins, minoxidil and biotin. Let It Thrive leaves out all three, on purpose. Here’s the short version of why, with links to the full stories. (General information, not medical advice.)

No drugs, no hype — the philosophy

Let It Thrive is cosmetic care built on two of the most-studied botanicals in scalp care, pumpkin seed and rosemary. It’s designed to support a healthy-looking scalp and the appearance of fuller, thicker-looking hair while conditioning lashes and brows — and it deliberately skips the three ingredients the category leans on hardest. Here’s why, in brief.

We skip minoxidil

Minoxidil is the proven over-the-counter regrowth drug — but it’s a lifetime commitment, comes with an unnerving early “dread shed,” and it’s genuinely dangerous to cats. If medical regrowth is your goal, that’s a route to discuss with a doctor; if you’d rather a gentle daily ritual — and not handle a substance that can be deadly to your cat — that’s us.

We skip biotin

Biotin is in every hair gummy on the shelf, but the evidence only supports it if you’re actually deficient (which is rare) — and high doses can skew medical lab tests. We won’t pad a formula with a hype vitamin. Full story: does biotin work for hair? →

We skip prostaglandins

Prostaglandins are the actives behind many lash serums, linked to documented side effects — darkened eyelids, a sunken-looking eye area, even a change in eye colour. Our lash and brow care conditions instead. Full story: prostaglandins in lash serums →

What we use instead

Pumpkin seed and rosemary, in gentle, cosmetic formulas you use daily. The honest caveat, because we don’t do hype: this supports the look of fuller, healthier hair, lashes and brows — it isn’t a treatment for hair loss.
