Hair thinning sends most people straight into a 2 a.m. research spiral — fifty tabs open, no idea which formula is actually worth the money. We pulled four of the more talked-about options right now, two built for men's pattern thinning, one formulated specifically for women, and one topical for anyone who'd rather skip the pills.
Here's how they break down.
| Product | Best For | Format | Key Ingredients | |

Profolan
Profolan keeps its formula tight instead of throwing in a long ingredient list — it centers on horsetail (a natural silica source), nettle leaf, and L-cysteine, an amino acid that's one of the building blocks of keratin. If you want a no-fuss, one-capsule-a-day habit rather than a routine with five steps, this is the simplest entry point on the list.
Best for: men who want one straightforward daily capsule, not a multi-step routine.
Locerin
This is the only formula on the list built specifically around female hair thinning rather than a men's formula with a pink label slapped on it. The 16-ingredient mix leans on biotin, MSM, and zinc — nutrients that consistently show up in hair-health research — alongside horsetail and nettle extract for the scalp side of things.
Best for: women who want a formula actually built for their hair cycle, not a repackaged men's product.
Folisin
Folisin takes a wider net than Profolan, packing in 13 ingredients aimed at common nutritional gaps that get linked to hair thinning — think of it as the option for guys who suspect diet and deficiency, not just genetics, are part of the picture. More ingredients also means more going on per capsule, which some people prefer and others find unnecessary.
Best for: men who want a broader nutrient-support formula, not just a 3-ingredient core.
Folicerin
The only non-capsule on this list. Folicerin is a daily shampoo built around caffeine and niacinamide — both common in topical hair-care formulas — plus ginseng and burdock root extract. If swallowing another pill every morning isn't appealing, this slots straight into a shower routine you're already doing.
Best for: anyone who'd rather build a habit into their existing shower routine than add a supplement.
What actually separates them
- Capsule vs. topical — some people will stick with a routine far longer if it's "add to shower" instead of "remember a pill."
- Formula breadth — a tight 3-ingredient core (Profolan) vs. a wider nutrient-gap blend (Folisin) suits different theories about what's causing the thinning.
- Whether it's actually formulated for the reader's sex, not just relabeled — Locerin is the one built specifically for women's hair cycles.
Before you buy
Results vary a lot person to person, and a lot depends on what's actually causing the thinning — nutrient gaps respond differently than genetic or hormonal hair loss. Ingredients like biotin, zinc, and horsetail show up consistently in hair-health research, but consistency of use matters more than any single ingredient. If hair loss is sudden, patchy, or comes with other symptoms, see a doctor before trying a supplement.
Hair grows in cycles that run several months, so most brands recommend at least 3 months of consistent use before judging results — this isn't an overnight category.
Mostly it comes down to which one you'll actually stick with. A shampoo swap requires zero extra effort since you're already showering daily; a capsule is one more thing to remember but lets you control the dose more precisely.
If you're on medication or managing an existing health condition, check with a doctor or pharmacist before adding any new supplement to your routine.
