Description
Advanced Hair Loss Prevention and Growth Serum RU-58841 5%( 50mg/ml) + Minoxidil 5% (50mg/ml)
RU58841 · A powerful anti-androgen
- Competes strongly against DHT, the main cause of androgen-related hair loss.
- Supports cellular replication in the hair matrix.
- Supports hair diameter, density, and the percentage of follicles in the anagen phase.
- Has shown growth outcomes comparable to or better than finasteride in preclinical research.
- Designed for localized topical use rather than systemic hormone suppression.
Minoxidil · 5% growth support
- Clinically established for supporting hair regrowth.
- Helps reactivate follicles and support the active growth phase.
RU58841 is a research chemical and is not FDA-approved for treating hair loss. Individual results vary.
How quickly can I expect results?
Early shedding may settle within 2 to 4 weeks. Visible improvements commonly take 3 to 6 months, with continued use supporting the strongest result.
How to Use
Apply 1 to 1.5 ml across thinning areas once daily. Massage gently into a clean, dry scalp and allow it to absorb. Do not rinse.
Is this safe to use?
This product is intended for topical cosmetic or research use. Review the ingredients and speak with a qualified doctor before starting any treatment.
Key Ingredients
RU58841 5% and Minoxidil 5% are combined in a lightweight topical carrier selected for direct scalp application.

It's fine.
Only used for two weeks now. The most welcome result is this application does not irratate my scalp. I was using standrad minoxidil 5% and I had terrible, terrible scalp irratation and buildup. Not so with Hair Rescue. The formulation is different with regards to the alcohol suspension delivery method. The viscosity is lower, not sticky or oily. This alone would be grounds for me to switch as the standard minoxidil was barely tolerable. As for results, too early to tell but I have very little shedding so that is progress. It does appear baby hairs are coming in, hard to tell, too soon. Will update after 90 days.

Great lightweight solution to combat hairloss
After 8 months of consistent usage, I can conclude this hairloss treatment has been the most effective for my mild case of MPB. The solution is non-greasy which means I can style my hair easily directly following application without worrying about my hair looking wet. Only reason this review is not 5-stars… the NEW bottles have been downgraded with a plastic dropper that doesn’t reach the bottom of the bottle. This minor design flaw is easily overlooked as you can tilt the bottle during extraction.

Highly recommended!
About 5 weeks in I am seeing less shedding in the shower and darker hair coverage, growth especially in crown area. Will continue to use 100%

It works!
My hair density increased, thickness and strength increased from the first week. While Hair Rescue has halted shedding there’s already a bald spot where there’s no hair so I don’t expect miracles. With combined hyaluronic acid and hair oils, I’ve got luster enough to comb over the balding areas with sustained volume.

Shedding has stopped!
Seems to be working good as shedding has stopped. Need more time for regrowth.

Two actives, one localized treatment
Prevention and regrowth in one daily serum.
Hair Rescue is the dual-active formula in the range. RU58841 is included for localized androgen-receptor support, while 5% minoxidil supports the follicle’s active growth phase.
Product distinction
RU58841 (5%) + Minoxidil (5%)
Product-specific mechanism
How Hair Rescue works
Targets DHT locally
RU58841 is a non-steroidal androgen-receptor antagonist designed to act where the serum is applied.
Supports active growth
Minoxidil 5% is the growth-supporting active in this formula and distinguishes it from the RU-only Solution.
One topical routine
Both actives are delivered together, so Hair Rescue Serum and the RU58841 Solution should be treated as alternatives, not layered.
