Whether you're familiar with this chemical in the hair loss community or wondering if it's in a lotion, RU58841 (also known as RU-58841, PSK-3841, or HMR-3841) is gaining attention for its positive impact on hair growth, especially for those who have exhausted other methods.

In this blog, we'll talk about this newer option called RU58841 and compare it with other well-known treatments. We want to help you understand your choices better so you can make informed decisions about tackling hair loss and regaining confidence.

Hair Loss and Its Common Causes

Hair loss, technically known as alopecia, occurs when hair falls out and doesn't grow back as it should. It's a natural part of life, but various factors can contribute to excessive or premature hair loss. Common causes include genetic predisposition, hormonal changes, certain medical conditions, and aging.

Hair loss symptoms are mainly characterized by an increase in hair loss, which may be subtle to detect. Identifiable clues include a widening part, indicating potential thinning hair, and a receding hairline, observed when the hairline appears higher than usual. Another sign is loose hair accumulating on brushes or combs, surpassing the typical amount.

Bald patches, varying in size and growing over time, are indicative of hair loss, along with clogged drains in sinks or showers due to excessive hair shedding. Pain or itching on the scalp may also signal an underlying skin condition contributing to hair loss.

Hair loss has diverse causes, categorized into common and rare types, each with distinct underlying factors. Androgenic alopecia, a hereditary form affecting both males and females, is the most prevalent cause, impacting up to 50% of individuals. It manifests gradually, with onset ranging from puberty to middle age. Female pattern baldness results in overall scalp thinning, often noticed after age 65, while male pattern baldness features progressive hair loss above the temples and crown, forming an "M" shape.

Hair Loss Symptoms:

  • Widening Part: Noticeable increase in part width, indicating potential hair thinning.
  • Receding Hairline: Higher-than-usual hairline, suggesting thinning hair.
  • Loose Hair: Excessive hair accumulation on brushes or combs after use.
  • Bald Patches: Varied in size, these patches may grow over time.
  • Clogged Drains: Sinks or showers with drains clogged due to hair shedding.
  • Pain or Itching: Scalp discomfort or itching, possibly linked to an underlying skin condition.

Causes of Hair Loss:

Androgenic Alopecia:

  • Overview: Hereditary hair loss affecting both males and females.
  • Prevalence: Affects up to 50% of individuals.
  • Onset: Gradual, with symptoms appearing from puberty to middle age.

Female Pattern Baldness:

  • Description: Results in overall scalp thinning.
  • Onset: Typically observed after age 65 but can start early in some females.

Male Pattern Baldness:

  • Features: Progressive hair loss above the temples and thinning at the crown.
  • Pattern: Forms an "M" shape.
  • Onset: Commonly noticed in middle age.

Popular Hair Loss Treatments

Numerous treatments are available to address hair loss, ranging from over-the-counter solutions to prescription medications. Some well-known options include Minoxidil, Finasteride, Lotions, and natural remedies. Each approach has its unique features and considerations.

All About RU58841

RU58841 is not a recent invention. French scientists first developed it in the 1970s during their investigations into treatments for prostate cancer. The goal was to create a non-steroidal, antiandrogenic compound for topical use, minimizing systemic side effects. After successful testing on rats, it was found to promote hair growth.

The researchers envisioned RU58841 as a potential treatment for androgen-dependent skin disorders such as acne and alopecia. However, before further research or production plans could be made, the company underwent a merger with two others. Unfortunately, for reasons that remain unclear, the project was dropped.

A few years later, ProStrakan acquired the rights to RU58841 and renamed it PSK3841. In 2005, the company announced plans for a Phase II trial with a full launch projected for 2010. While Phase I and II trials were conducted, Phase III research never began.

As of today, there is no ongoing research into RU58841. Unless there is a dramatic development, this drug will never come to market. It is not only unlicensed for hair loss but not even approved for use in humans.

Mechanism of Action

RU58841 primarily works by targeting and inhibiting the activity of androgens, specifically dihydrotestosterone (DHT). DHT is a hormone linked to hair loss, particularly in individuals with a genetic predisposition. By blocking the effects of DHT on hair follicles, RU58841 aims to impede the progression of hair loss and stimulate regrowth.

The Impact of DHT on Hair Loss

There is presently no definitive explanation for the correlation between DHT and alopecia.

Upon the conversion of testosterone to DHT, a portion reaches the hair follicles, binding to androgen receptors on dermal papilla cells. This binding initiates a series of events within the cell's cytoplasm, involving modifications to gene functions.

Follicular cells compromised by DHT undergo changes in the growth cycle, notably reducing the anagen phase duration. This premature stoppage of rapidly dividing cells forming new hair results in successive hair growth cycles producing shorter and thinner strands—a process known as miniaturization.

Balding scalps often face a secondary issue of poor blood circulation and impede the supply of essential nutrients like vitamins, minerals, antioxidants, and proteins to the cells. This further diminishes the average growth span of follicles and intensifies developmental challenges.

The adverse effects of DHT on hair growth manifest gradually, and the progression of male pattern baldness is a slow, incremental process.

The Science of RU58841

Several conventional hair loss drugs, including finasteride (Propecia), operate by specifically inhibiting 5-alpha reductase, the enzyme responsible for converting testosterone into DHT.

However, systemic reduction of DHT impacts all body tissues, not just hair follicles. In contrast, RU58841 functions as a topical anti-androgenic. By binding to androgen receptors at hair follicles, it counteracts DHT effects, preventing its binding to these receptors. This interruption avoids the initiation of miniaturization and allows hair to undergo its regular growth cycle.

RU58841 additionally supports cellular recovery to provide damaged follicles with time to transition back to a normal anagen phase.

Being topical, RU58841 does not impede DHT production in the body and the blood DHT levels remain unaffected. This targeted approach minimizes the risk of systemic side effects associated with many other hair loss treatments.

Unique Characteristics

One notable aspect of RU58841 is its topical application. Unlike some treatments that are ingested orally, RU58841 is typically applied directly to the scalp. This localized application is thought to enhance its effectiveness in targeting the hair follicles without affecting the body's overall hormonal balance. 

Comparison with Other Treatments


Minoxidil is a widely used over-the-counter topical solution for hair loss. It works by dilating the blood vessels near the hair follicles, increasing blood flow, and stimulating hair growth. Essentially, it provides a boost to the hair follicles, encouraging them to grow thicker and stronger hair.

Pros of Minoxidil

  • Accessibility: Minoxidil is readily available without a prescription, making it easy for users to obtain.
  • Topical Application: Like RU58841, Minoxidil is applied directly to the scalp, allowing for targeted treatment.
  • Potential Effectiveness: Many users report positive results, including hair regrowth and increased thickness.

Cons of Minoxidil

  • Continuous Use Required: To maintain results, Minoxidil often requires ongoing and consistent application.
  • Limited Efficacy for Everyone: While effective for many, Minoxidil may not work equally well for everyone, and results can vary.
  • Possible Side Effects: Some users may experience side effects, including scalp irritation, itching, or dryness.

Potential Side Effects or Limitations

Minoxidil's side effects are generally mild, but users should be aware of potential scalp irritation or allergic reactions. Additionally, it might not be suitable for those with certain skin conditions or allergies. The need for continuous use to sustain results may be considered a limitation for some users.

Possible Side Effects:

  • Itching or skin rash (continued)


  • Acne at the site of application
  • Burning of the scalp
  • Facial hair growth
  • Increased hair loss
  • Inflammation or soreness at the root of the hair
  • Reddened skin
  • Swelling of the face

Signs and Symptoms of Excessive Absorption

  • Blurred vision or other changes in vision
  • Chest pain
  • Dizziness
  • Fainting
  • Fast or irregular heartbeat
  • Flushing
  • Headache

  • Numbness or tingling of hands, feet, or face
  • Swelling of face, hands, feet, or lower legs
  • Rapid weight gain

Important Note: If any of these side effects occur, it's must to reach out to a doctor promptly. Not everyone may experience these effects, but being aware and seeking medical attention if needed is essential for your well-being.


Finasteride is an oral prescription medication that tackles hair loss by inhibiting the activity of an enzyme called 5-alpha-reductase. This enzyme is responsible for converting testosterone into dihydrotestosterone (DHT), a hormone linked to hair loss. By reducing DHT levels, Finasteride aims to slow down hair loss and promote hair regrowth.

Pros of Finasteride:

  • Proven Effectiveness: Finasteride has been clinically proven to be effective in addressing male pattern baldness.
  • Convenient Oral Administration: It comes in pill form, making it easy for users to incorporate into their daily routine.
  • Potential for Long-Term Results: Finasteride may provide sustained benefits over the long term when taken consistently.

Cons of Finasteride:

  • Prescription Required: Unlike some over-the-counter options, Finasteride needs a prescription from a healthcare professional.
  • Varied Individual Responses: While effective for many, individual responses to Finasteride can vary, and not everyone experiences the same degree of success.
  • Continuous Use Necessary: Similar to Minoxidil, Finasteride typically requires ongoing use to maintain results.

Potential Side Effects and Considerations

Finasteride is generally well-tolerated, but users should be aware of potential side effects, including decreased libido and erectile dysfunction. Some individuals may experience mild to moderate side effects, and it's essential to consult with a healthcare professional before starting Finasteride, especially for those with pre-existing medical conditions.

RU58841 Outperforms Finasteride in Monkey Study

Scientists studied how two different medicines affect hair growth in monkeys. They used 20 bald macaques, which have similar hair loss patterns to men. Ten monkeys took finasteride pills, and ten had RU58841 applied on their skin.

After six months for finasteride and four months for RU58841, they checked the hair follicles. The RU58841 group showed a remarkable 103% increase in healthy hair, while finasteride had an 88% increase.

They also measured testosterone and DHT levels. Finasteride lowered DHT and raised testosterone, while RU58841 had no significant changes.

In simple terms, the study suggests that blocking androgen receptors (with RU58841) is better for hair growth than targeting the 5-alpha reductase enzyme (with finasteride). (Source)


Dutasteride is another oral prescription medication designed to address hair loss. Similar to Finasteride, Dutasteride targets the enzyme 5-alpha-reductase, but it inhibits both Type I and Type II forms of the enzyme. This dual inhibition results in a more comprehensive reduction of dihydrotestosterone (DHT) levels, aiming to effectively combat hair loss.

Pros and Cons of Dutasteride compared to RU58841

Pros of Dutasteride:

  • Comprehensive DHT Inhibition: Dutasteride inhibits both Type I and Type II forms of 5-alpha-reductase, potentially providing more thorough suppression of DHT compared to RU58841.
  • Clinically Studied: Dutasteride has undergone clinical studies for hair loss, demonstrating its efficacy in certain cases.

Cons of Dutasteride:

  • Prescription Requirement: Like RU58841, Dutasteride requires a prescription, limiting accessibility compared to over-the-counter options.
  • Potential Side Effects: Dutasteride, similar to Finasteride, may lead to side effects such as decreased libido and erectile dysfunction.

Situations where Dutasteride may be more suitable

  • Advanced Hair Loss: Dutasteride might be considered for individuals with more advanced stages of hair loss, where a stronger inhibition of DHT is desired.
  • Limited Response to Other Treatments: For individuals who have not responded well to other treatments like Minoxidil or Finasteride, Dutasteride could be a consideration.

While Dutasteride shares similarities with RU58841 and other treatments, its unique features make it a potential choice for specific situations. However, users should consult with healthcare professionals to determine the most suitable option based on individual needs and health considerations.

Natural Remedies

Natural remedies for hair loss have gained popularity, with various options often rooted in herbal extracts, essential oils, and dietary changes. Examples include saw palmetto, rosemary oil, aloe vera, and changes in diet to include nutrient-rich foods.


  • Some individuals report positive results with natural remedies, including reduced hair shedding and improved hair thickness.
  • Certain components, like essential oils, may have properties that nourish the scalp and promote a healthier environment for hair growth.


  • Scientific evidence supporting the effectiveness of many natural remedies is often limited or inconclusive.
  • Results can vary significantly among individuals, and the efficacy of natural treatments may not match that of clinically proven options.

Comparison with RU58841

  • Scientific Basis: RU58841 operates on a more scientifically established basis. It targets specific mechanisms involved in hair loss.
