Great

I started applying 0.5ml a day, then increased to 1ml a day 4 months ago. From the moment I started , I noticed that the shedding had stopped. During the past couple of months, I’ve noticed my hair growing darker and stronger around my hairline. I’m very happy

Phenomenal!

I can clearly see that hairs along my hairline are filling in nicely. My confidence is back. Besides, the product doesn’t leave any side effects. I still have 2 bottles and I intend to take them with me on my trip to Asia. When I am back to the US, will definitely reorder some. Thank you.

Not sure yet, gotta wait for the full results at 6 months.

I think it’s gotten thicker but hard to tell, waiting to see full results at six months since I’ve only been using it for a 1 1/2 months

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

01

Targets DHT locally

RU58841 is a non-steroidal androgen-receptor antagonist designed to act where the serum is applied.

02

Supports active growth

Minoxidil 5% is the growth-supporting active in this formula and distinguishes it from the RU-only Solution.

03

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.
