COMPLETE TRANSPARENCY

The evidence behind every ingredient.

We only use actives with published clinical data. Here is exactly what we use, why we chose it, and how it compares to the biggest names in the category.

Our Core Actives — The Data

Caffeine 1% in serum

Key Study: Dhurat et al. 2017 (n=210 men with AGA) — 0.2% caffeine topical was non-inferior to 5% minoxidil after 6 months on anagen hair ratio.

One of the strongest pieces of evidence for any cosmetic hair active. Excellent safety.

Adenosine 0.75% in serum

Key Studies: Multiple RCTs (Oura 2008, Iwabuchi 2016, Watanabe 2015) showed significant increases in thick terminal hairs and hair density. One head-to-head vs 5% minoxidil showed comparable results with higher patient satisfaction.

Particularly strong for improving hair thickness and quality.

Piroctone Olamine 0.75%

Key Study: Piérard-Franchimont 2002 (n=150) — 1% piroctone olamine shampoo reduced shedding by ~16.5% and increased anagen hairs by +7.9%, performing comparably or better than 1% ketoconazole on several metrics.

Exceptional for scalp health — the hidden driver of many thinning cases.

Capixyl 3.5% in serum

Key Study: Proof-of-concept RCT (n=30) showed +46% improvement in anagen/telogen ratio after 4 months vs –33% for placebo. Combines mild 5α-reductase inhibition with improved follicle anchoring.

How We Compare

Our Evidence Principles

We prioritize published RCTs

Especially head-to-head studies against minoxidil where available.

We use meaningful percentages

Not trace amounts for marketing claims. Real doses that appeared in studies.

We stay in the cosmetic lane

Honest about what these ingredients can and cannot do. No drug claims.

Why This Combination Works

Multi-pathway approach. Hair thinning is rarely caused by one single factor. Our formula attacks it from several angles at once: follicle stimulation (Caffeine + Adenosine), local DHT/anchoring support (Capixyl + Saw Palmetto), scalp microbiome & inflammation control (Piroctone Olamine), and modern + traditional anti-fibrosis support (Diaminopyrimidine Oxide + Platycladus orientalis).

Scalp-first philosophy. Many people experience increased shedding because of an unhealthy scalp environment long before follicle miniaturization becomes severe. Piroctone Olamine at meaningful levels is one of the smartest moves we could make for real-world results.

Consistency over miracles. The best data in this category comes from people who use their products every single day for 4–6+ months. Our system is designed to be pleasant enough that people actually stick with it.

Important Note on Claims

All of our marketing and packaging language stays strictly within cosmetic boundaries. We do not claim to treat androgenetic alopecia or any medical condition. We present the published data on the individual ingredients and let customers make informed decisions. This approach protects both our customers and the brand long-term.
