I dig it!

Only been through my first vile but my hair is feeling thicker and fuller! Going to continue using and will update my review after a few more months, but so far it’s going well!

This stuff works

I’ve been on it since November the first, it’s now the 15th of December and my shedding has reduced from well over a hundred lost in every shower to maybe 3 or 4. I’ve got quite a sensitive scalp but it hasn’t really irritated it to be fair. Be prepared if you haven’t used minoxidil before it will cause a shedding phase for maybe 3-4 weeks as it did for me but stick through it and it’ll grow back so much stronger. I’m excited for the next few months of growth to come, I can already see tiny baby hairs on the corners of my hairline.

Loving it so far

Been on it for nearly 3 months now. Shedding has reduced massively. As far as I am concerned no side effects from it other . Itchy scalp if you dont shampoo for about 4 days but that is normal. Time to start ordering my next batch and hopefully the new growth starts to come around this point.

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%
