99% Ru58841 Powder

RU58841 (CAS 154992-24-2), also known as HMR 3841 or PSK-3841, is a high-efficiency, tissue-selective non-steroidal anti-androgen compound. Originally developed for targeting androgen-dependent physiological disorders, this premium active ingredient has become a core material in high-end cosmetic formulation, dermatological research, and hair loss intervention studies worldwide. Unlike steroidal anti-androgen ingredients, RU58841 delivers exclusive topical efficacy with zero systemic hormonal interference, ensuring higher safety and wider application compatibility.

As a potent and targeted DHT (Dihydrotestosterone) blocker, RU58841 competitively binds to androgen receptors located in human scalp hair follicles. It effectively blocks the combination of DHT and hair follicle receptors, fundamentally inhibiting DHT-induced hair follicle miniaturization, atrophy, and hair follicle dormancy. This mechanism perfectly targets the root cause of androgenetic alopecia, the most common type of hair loss for both men and women. It can effectively revive dormant hair follicles, improve scalp microcirculation, accelerate hair follicle metabolism, and significantly enhance hair density and thickness.

Compared with traditional hair growth active ingredients such as Minoxidil and Finasteride, RU58841 features stronger receptor affinity, longer biological half-life, more stable topical activity, and no systemic side effects. It does not affect the body's overall hormone balance, making it safer for long-term topical use. At present, it is widely recognized as a top-tier raw material for high-end anti-hair-loss serums, scalp care sprays, and professional dermatological research. We supply factory-direct RU58841 powder with 99% high purity, strict batch-to-batch quality control, complete authoritative certifications, and stable global bulk supply for cosmetic manufacturers, research laboratories, and global distributors.

Androgenetic alopecia is mainly caused by the excessive combination of DHT and hair follicle androgen receptors, which leads to continuous hair follicle shrinkage, shortened hair growth cycle, and progressive hair thinning. RU58841 exerts its anti-hair-loss and hair-regrowth effects through a precise and scientific targeted mechanism.

As a selective non-steroidal androgen receptor antagonist, RU58841 possesses extremely high receptor binding affinity. When applied topically to the scalp, it preferentially binds to androgen receptors in hair follicle cells, occupying the binding sites of DHT. It effectively blocks DHT from attaching to hair follicle receptors, terminates the adverse biological reaction caused by DHT, and stops hair follicle atrophy and damage.

Furthermore, RU58841 can improve scalp blood microcirculation, supplement nutrient supply for hair follicles, activate dormant hair follicle stem cells, prolong the anagen phase of hair growth, and shorten the telogen phase. Different from systemic anti-androgen substances, RU58841 only acts locally on the scalp without entering the systemic circulation in large quantities, so it will not interfere with human endocrine and hormone levels, ensuring high safety for long-term topical application.

99% Ultra-High Purity & Strict Impurity Control: Our RU58841 powder is produced through multi-stage chemical synthesis, repeated recrystallization and high-precision purification technology. The HPLC purity is stably above 99%, with ultra-low organic impurities and zero heavy metal residues. All products comply with EU cosmetic raw material standards and international research chemical specifications, fully meeting the strict requirements of high-end cosmetic formula development and academic laboratory precision experiments.

Superior Targeted DHT Blocking Efficacy: RU58841 has stronger androgen receptor affinity than conventional anti-hair-loss ingredients. It can efficiently and competitively block DHT-induced hair follicle damage, reverse follicle miniaturization, activate atrophic hair follicles, and promote healthy hair regrowth. The effect is more stable, lasting and obvious for hereditary hair loss, androgenetic alopecia and hormone-induced hair thinning.

Long-Lasting Stable Topical Activity: Featuring stable chemical molecular structure, RU58841 is not easy to decompose in conventional cosmetic solvents and liquid formulas. Its effective topical activity can last up to 48 hours, greatly improving the durability of product efficacy. It perfectly adapts to long-acting scalp care products and reduces the frequency of repeated use, bringing better user experience.

High Safety & Excellent Formula Compatibility: Adopting non-steroidal molecular structure, RU58841 completely avoids systemic hormone side effects. It is mild and non-irritating to scalp skin, without sensitization, redness or swelling risks. It has high compatibility with ethanol, DMSO, plant extracts and various cosmetic base materials, with simple formula matching and stable long-term storage performance.
