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.

love this stuff

after starting TRT i experienced massive shedding. I was using RU58841 from another source and wasnt seeing results. i changed to hair rescue and my hair loss has completely stopped after 2 months of use.

So far so good, not sure yet

I am on my second bottle, I think I see some improvement but it's too early to tell. I will keep going!

Incredible!

It works

Great!

SIGNIFICANTLY reduced shedding - I have very high DHT levels from certain “supplements” I take and was experiencing noticeable shedding. About 3(ish) weeks after introducing this stuff the shedding was drastically reduced - They must mix it fresh because this stuff breaks down quick but what I got from these guys works like a charm! Very impressed!

It lowkey does work

I didnt really see results until now ( 3months in) my thinning was down the middle and my crown and its definitely more thicker. I applied it on my corners even though i did not need it but even doing that helped. i would highly recommend using a dermaroller once a week, also make sure not to apply serum right after. wait a day until applying it and

Hair Rescue Serum bottle with RU58841 and Minoxidil label

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.

Formula

The two active ingredients

RU58841 · 5%

Localized, non-steroidal androgen-receptor support.

Minoxidil · 5%

A topical active used to support the hair-growth cycle.

Topical carrier

A lightweight base selected for direct scalp application.
