There’s a lot of talk about caffeine for hair growth — and here’s why:

✅ Results comparable to Minoxidil (but without the side effects)

✅ Extends the growth phase of your hair

✅ Protects hair follicles from DHT — the #1 hair killer

Sounds good — but does it actually work?

What does caffeine really do for your hair?

You know it as a morning energy boost.
But on your scalp? It does something completely different:

✔ Neutralizes the effect of DHT
DHT shrinks your hair follicles. Caffeine helps stop that process. (Fischer et al., 2007)

✔ Extends the growth phase
Your hair stays in the growth cycle longer before falling out.

✔ Boosts cell activity in your follicles
More IGF-1 = more hair growth. (Fischer et al., 2014)

✔ Improves blood flow to your scalp
Which means stronger, healthier hair follicles.

What does the science say?

📌 2007 – Lab test on human hair follicles
Testosterone (converted into DHT) reduced hair growth.

Add caffeine? Growth returned to normal.

📌 2014 – Growth factors and cell stimulation
Caffeine increased the production of IGF-1, a key growth factor. Study shows caffeine reduces hair loss.

📌 2018 – Caffeine vs. Minoxidil
0.2% caffeine was tested against 5% minoxidil.
After 6 months: similar regrowth results.

How should you actually use caffeine?

Drinking coffee? Nope.
You’d need crazy amounts to reach your scalp — and you’d crash long before you grew new hair.

What does work?

👉 A leave-in caffeine serum — so it actually stays on your scalp
👉 Combine it with DHT blockers — like saw palmetto or Capilia Longa stemcells.

What about caffeine shampoo?
It rinses off in 30 seconds = not enough time to do anything.

Verdict: does caffeine work?

✅ Yes. There’s solid science showing that caffeine helps reduce hair loss —
especially when applied topically and combined with other proven ingredients.

Our take?
Caffeine works — but only when used properly. Not from your coffee mug, but directly on your scalp.
And ideally with natural DHT blockers like saw palmetto.
