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.

Steady thickening ... l can feel it when l apply & message it in & run my hand thru my hair

I took pics ... but the change visually is not dramatic because my hair thinned over a larger general area. I never had bald spots, just noticeably thinner hair. I have been using a DHT blocking shampoo for about a year, so that reduced the hair loss ... what I really needed was new hair growth. I started seeing it in the front at the crown ... tiny little hairs ... those tiny little hairs are now, long hairs that noticeably have thickened my hair over my entire scalp. It's working, every day ... slow & steady wins the race! And I like that the Hair Rescuse formula doesn't make my hair feel stiff and dry ... other minoxidal treatments did ... l actually think sometimes the hair would break just because it was so stiff & stuck together. Good product good results so far!

Spectacular!

3 months and my hair is back. This and the essential oil topical once a day, combined with minoxidil/dutastaride/tretinoin topical at night. Going to keep using this for a year and see how far i can get. I also combined it wiah a healthy diet, kidney/liver supplements, microderm stamping once a week. .25mg of dutastaride oral and .5 mg of minoxidil oral every day. Ive also been getting prp once a month with exasomes. 3hp lotion as well. But hair rescue tied it all together.

Remarkably effective

This product will grow your hair if you stick to it

Verified customer

Remarkable!

Easy to order and simple to use, and they can already start to see hair sprouting up. I’m only one month in so I’m anxious to see what month two will unlock.

Verified customer

You should get this!

Helps hair loss. Definitely decreased it a good amount. Hair seems stabilized as well. The minoxidil is helping it grow and makes it look fuller

Verified customer

Phenomenal!

This actually works. I’m shocked. New growth popping up like crazy, where dutasteride, peptides, and minoxidil alone did literally nothing. Even my barber is like “bro wtf have you been doing to your hair, you have so many baby hairs poppin up that it’s hard to hit a clean part when I’m cutting your hair. Honestly I was pretty hopeless about my hair situation but this is truly and shockingly a game changer

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.
