Radix is a solid hair soap with rosemary oil and rosemary leaf extract as its main active ingredients — complemented by onion extract, oats, and shea butter. Rosemary is traditionally used to stimulate scalp circulation, while onion extract additionally provides sulfur-containing compounds associated with hair growth. Many report stronger, shinier hair with regular use.
In a 2015 clinical study (Panahi et al., Skinmed), rosemary oil was compared to 2% minoxidil over 6 months for androgenetic alopecia—both groups showed a comparable increase in hair density, with rosemary oil resulting in fewer side effects such as itching. Onion extract was investigated in another study (Sharquie & Al-Obaidi, Journal of Dermatology, 2002) in the context of hair growth for alopecia areata. Radix combines both active ingredients in a solid soap form.
Yes. Radix is sulfate-free and designed for daily use on the scalp and hair. For sensitive scalps, we recommend a patch test on the inside of the forearm beforehand. Discontinue use if redness, itching, or irritation occurs. Do not use on open wounds or irritated scalps. Avoid contact with the eyes.
Thoroughly wet hair. Lather Radix between your hands or directly on the scalp. Gently massage into the scalp for 2–3 minutes to allow the active ingredients to take effect. Rinse thoroughly. For visible results, use 2–3 times a week for several weeks.

Clinically tested
In a randomized study with 100 participants (Skinmed, 2015), pure rosemary oil showed a comparable increase in hair count to 2% minoxidil after 6 months—with less scalp irritation. Onion extract was investigated in another study (Journal of Dermatology, 2002) for alopecia areata and showed a significantly faster response there than the control group.
Activated bamboo charcoal binds excess sebum and impurities deep within the pores.

I stumbled upon Radix by chance at first, because I had been noticing for a while that my hair was getting thinner, even though I'm still young. After about 2 months of regular use, I can already see a difference, especially at the roots.

I was skeptical that a soap would actually do anything. I've been using it 3 times a week for 10 weeks now. I can't say if it's due to the rosemary or just the regular scalp massage, but my part definitely looks fuller than before.

I use Radix as part of my regular hair wash, no extra effort. The scent is subtle, not overpowering. I'm not 100% sure yet if it's affecting hair growth, but my scalp definitely feels better than before.

I noticed slight receding temples at 26 and was initially embarrassed to even Google it. Radix was one of the first products that wasn’t hyped up with exaggerated claims. I’ve been using it for 6 weeks now and I really think things are changing. Great product!

I was pretty frustrated due to hormonal hair loss. After 3 months of Radix, I can really see new hairs in the thin areas; it takes patience, but things are definitely happening.

After barely 3 months of regular use, I can see new, short hairs actually growing back at my temples. I wouldn't have thought a soap could do that, but it works for me.

I already noticed my hair thinning on the top of my head at 24, which was pretty unsettling at that age. After 3 months with Radix, there is significantly more volume again; even my hairdresser asked what I'm doing differently.

For me, it started around month 3, suddenly noticing new short hairs at the hairline where there was nothing before. I'm surprised myself at how well it's working.

At my age, I didn't expect any new hair growth. After almost half a year, there is noticeably more hair on the top of my head than before. It takes patience, but it's worth it.

After my pregnancy, I lost an extreme amount of hair and was already fearing the worst. After about 4 months of Radix, my roots are significantly thicker again; I'm really relieved that things are still happening there.

Frequently Asked Questions
Is Radix suitable for sensitive scalps?+
Yes, Radix is mildly formulated and sulfate-free, making it well-suited for sensitive and irritated scalps. For very sensitive skin, we recommend performing a patch test on the forearm beforehand.
When will I notice a difference?+
The scalp usually feels more comfortable after just the first application. Visible changes to the hair take time — the first effects often appear after 4-6 weeks of regular use, with noticeable results after 3-6 months.
Can I use Radix daily?+
We recommend 2-3 applications per week. More frequent washing can unnecessarily stress the scalp without accelerating the effect.
Does the soap feel heavy or greasy on your hair?+
No, Radix lathers finely and rinses out thoroughly without leaving any residue. The hair feels clean and weightless afterward.
Does Radix also work preventively, or only once the hair is already thinning?+
Radix can be used in both cases — both preventively to support a healthy scalp and when hair loss has already been noticed.
