What is RU58841?

RU58841 is an androgen receptor antagonist. This non steroidal topical androgen antagonist was investigated for therapeutic value in androgenetic alopecia (pattern baldness) and acne. In studies and clinical trials RU58841 has shown to strongly compete against DHT at the androgen receptor. The researchers noted that topical application of RU58841 at the test subject increased the hair densitity, increased the percentage of hair in the anagen phase and provided a better netto growth of hair.

What Are Essential Oils?

Essential oils are proven to help against hair loss. Our solutions that are enriched with essential oils, will increase circulation in the scalp similar to the effects of Minoxidil, but without a shedding phase and other Minoxidil related side effects. Our solution contain pepermint oil, tea tree oil and lavender oil. These essential oils alone work great for reducing hair loss and recude scalp inflammation. The combined oils make a synergic effect, that will calm down the inflammed scalp, increase circulation and stimulate hair follicles.  When applied, the scalp will immediately feel calmed down, due to the cooling and inflammation reducing effect of essential oils.

What is OctoPirox (Piroctone Olamine)?

OctoPirox, also known as piroctone olamine, is a chemical very much related to ketoconazole. It has proven its effeciacy in various studies. One of these studies is summarized here below.

A study of 150 men with androgenic alopecia and dandruff compared Ketoconazole and Piroctone Olamine. Excessive sebum secretion, dandruff and seborrheic eczema are often associated with hair loss and androgenic alopecia. The 150 men were given a shampoo containing 1% Ketoconazole or 1% Piroctone Olamine. They had to use this shampoo 2-3 times a week for six months.

Both treatments showed a reduction in itching and dandruff after two to six weeks. Looking at the effect of the treatments on different hair growth parameters, the following figures (in percentages) can be seen:

  • Hair loss decreases: (Ketoconazole: -17.3%, Piroctone Olamine: -16.5%)
  • The percentage of hair in the growth phase increases: (Ketoconazole 4.9%, Piroctone Olamine: 7.9%).
  • The hair diameter increases: (5.4% increase with Ketoconazole and 7.7% with Piroctone Olamine)
  • The study thus shows that Piroctone Olamine scores better than Ketoconazole on a number of levels.

Compared with Ketoconazole, Piroctone Olamine increases the number of hairs in the growth phase (anagen phase) by more than 10% in 33% more people.
With Piroctone Olamine, 88% of people get increased hair thickness, despite androgenic alopecia, whereas with Ketoconazole this is 78%.

    Took some months for it to show effects, but I’m more than happy right now. Before I only used Finasterid for like 20 years. My hair got less and less over the years regardless. Then I used minoxidol additionally and for some months it was AWESOME. No hairloss at all and thicker hair. But then without me changing anything the hairloss was extreme. It seemed that all the hair I managed to save over the years were now finally dying. It went on for months and months. It wasn’t just a phase as many people try to tell me. Then my last hope RU58841. It didn’t seem to work for months, but I kept on using it as I had no other hope anyway. Now my hair looks really good. Of course it’s no like it was when I was 18. It will never be that thick again. Some hair coming and going, but hair looks really fine in the end. One big problem less in my life.

  15. Timo

    When i just started, the first thing i noticed was that the infamous itch that i always associated with hair loss, slowly went away. Hair loss continued, however.
    Until one month ago, four months after starting this product. I have seen mild regrowth of the hairline and, way more important, thickening of the diffusely thinning vertex area.
    Very satisfied! Hope that these results will prevail!

  16. milan

    using this for 6 months makes my hair very thick and no hair loss anymore

    Hi, the delivery worked very well. I take the product the first time, and I began for a few days. I m not able to say how good it is, or if it works well, but I will tell u in a few weeks.
    The only strange thing is, that my hole body itches since I began with Ru.

  25. Mark0s
