The truth

Arginine or Caffeine in Shampoo - What Really Works

Arginine vs. Caffeine

Why we rely on Arginine.

Arginine occurs naturally in hair. It supports blood circulation in the scalp and activates processes in the hair follicle that are crucial for vital hair. For us, it is not a filler, but a targeted active ingredient.

Studies show: For a measurable effect, caffeine would have to remain on the scalp for several hours. With a shampoo that you rinse out after 2 minutes, this is simply not possible.

Mode of action

What's in Arginine Shampoo for Men

Arginine activates the hair root
Mode of action
Arginine activates the hair root
Arginine is a precursor to nitric oxide (NO). NO relaxes the blood vessels of the scalp – the hair root is better supplied with blood and nutrients.
The Foundation for Hair Growth
Microcirculation
The Foundation for Hair Growth
In areas affected by hair loss, microcirculation is significantly reduced. Arginine promotes follicle circulation, supplying the roots with oxygen and nutrients again.
Wheat protein strengthens from within
Hair fiber
Wheat protein strengthens from within
Hydrolyzed wheat protein penetrates the hair structure and fills structural gaps. Hair becomes thicker and more resilient – fuller after every wash.
Argan oil protects and regenerates

Rich in vitamin E and essential fatty acids, argan oil seals the hair cuticle, reduces moisture loss, and nourishes the scalp. Visible shine - without silicones.

Why a Barber Developed a Shampoo Against Hair Loss

For over 10 years, Ahmed Al-Musawi worked in his barbershop in Düsseldorf. Thousands of men. Thousands of conversations. One question remained: Why is there no grooming product that truly delivers on its promises?

Application

How to use men's shampoo correctly: 60 seconds

Most men wash too quickly. This is the only step that really matters.

1
💧
First wash
Distribute a small amount of shampoo in wet hair to remove residue, styling products, and excess oil. Rinse thoroughly.
2
🤲
Second wash cycle
Apply shampoo to your hair again and massage it thoroughly into the scalp and hair lengths. Now the actual care begins and the active ingredients penetrate.
3
Leave on for 60 seconds
Gently massage into the scalp and leave on for 60 seconds, do not skip.
4
🚿
Rinse
Rinse thoroughly with clear water until hair is clean.
💡
Why 60 Seconds Matter
During this time, arginine activates the microcirculation of the scalp through the formation of nitric oxide (NO)—the decisive mechanism of action. Rinsing sooner means missing out on the main effect. Recommendation: 3–4 times per week. Mild enough for daily use.

Frequently Asked Questions

Frequent questions about anti-hair loss shampoo

A shampoo cannot stop hereditary hair loss — no cosmetic product can do that. What a good men's shampoo can do: improve the condition of the scalp, support blood circulation, and strengthen existing hair so that it appears fuller and breaks less. Look for high-dose arginine, the absence of aggressive sulfates, and a pH-skin-neutral formula. In the case of sudden or circular hair loss, the cause should be clarified by a doctor before you change care products.
Men's hair needs fewer products than the shelves suggest—but it needs the right ones. The foundation is a shampoo that doesn't dry out the scalp: pH-skin-neutral and without aggressive sulfates in high doses. Those prone to hair loss should add active ingredients for scalp circulation such as arginine. A separate conditioner is usually unnecessary for short hair. More important are two habits: not washing with water that's too hot, and gently massaging the scalp for half a minute while shampooing.
Yes. Our shampoo is sulfate- and silicone-free, making it gentle enough for daily hair washing. Important: Shampoo twice – the first wash removes dirt, and the second allows the active ingredients to penetrate.
Our shampoo contains arginine, an amino acid that is a natural component of skin and hair. In combination with menthol, arginine can support the microcirculation of your scalp. This creates a nourished foundation on which healthy-looking hair can develop. A shampoo alone is not a substitute for medical treatment and does not work overnight. However, with regular use, it can make a positive contribution.
Arginine acts in two ways: at the root and on the hair shaft. By forming nitric oxide, it promotes microcirculation of the scalp — particularly in areas affected by hair loss, where this blood flow is significantly reduced. On the hair itself, arginine strengthens the structure. Experience shows that results become visible from week 3 to 4 of regular use. If you don't see a difference after one week, it's not because you're using the wrong product, but because you've looked too soon.
Our formula is free of parabens and sulfates and has been developed to be well tolerated even by sensitive scalps. Aloe vera and coconut water have a soothing effect, while menthol provides gentle refreshment. Every person reacts differently. If you are particularly sensitive to fragrances, we recommend our fragrance-free version with the same care formula.
With daily use and double washing, a 250ml bottle lasts approximately 4–6 weeks.
