Fantastic product

Fantastic product. I’ve used it on my temples to stop them going back and it’s working excellently. It’s a massive massive confidence boost to know not only my hairline is not going back, but actually regrowing forward. If you’re considering buying, it’s a no brainer.

Bought Rurestore for my son

Bought Rurestore for my son who had lost so much confidence because of his hair. He never wanted to go out, always wore a hat and was even considering a hair transplant. I found Rurestore through my research and honestly, it’s been amazing! His confidence is back, he’s going out, living life and even has a girlfriend! ❤️ Thank you, Rurestore — you’ve made such a difference! 🥰

RUrestore products

I have been using RUrestore products for nearly 6 months now and the results have been great and have not experienced any side effects. I have always received responses promptly to all my questions and have been given some great advice. I would recommend everyone to try the products for themselves as I was initially hesitant myself.

It was freakin amazing

It was freakin amazing, started off as a joke after my friend recommended me.. I was like I failed so many times, might as well give it a try.. this actually worked lol. In the beginning it was slow but I could see the results.. I realized when I met my ex and she said wtf you’ve done to your hair… that’s when I knew it worked.. So yeah.. great product.. must try for someone who is patient and actually needs results..

I had a hair transplant about a year ago

I had a hair transplant about a year ago and was not too happy with the results, was quite stressed about it having spent decent money and wasnt sure what to do. My crown area especially looked the same as before I had the hair transplant. Thankfully I came across Charlie and his amazing solution. Within 3 months my hair looks so much better, thicker and the crown area is getting thicker. I've just got the 3 month supply and have started to recommend the solution to my friends and family.

Excellent customer service

Purchased 3 bottles of RU58841 for £120. Unfortunately I experienced some undesirable side effects shortly after initial application. I reached out to Charlie and explained my situation. He was very understanding and sympathetic, and kindly offered to refund my purchase on return of unused product. Whilst I am disappointed that I am unable to continue with the use of the product, this is not the fault of the vendor, and I am very pleased with the excellent level of customer service I received. If you are looking for a reputable and reliable source for RU58841, then I have no hesitation in recommending this company. 5 Stars awarded for excellent customer service.

5% RU58841 in an Ethanol and Propylene Glycol base to maximise absorption and effectiveness

Hair growth cycles are slow, and most topical hair loss treatments require consistent daily use for 3 to 6 months before visible results become apparent.

We recommend a minimum 90-day protocol, which is why our bundles include a 3-month supply. Early signs of progress may include reduced shedding within the first 2 to 4 weeks, with new growth becoming visible from months 2 to 3 onwards

Apply 1ml (approximately one full dropper) to the affected areas of the scalp once daily, preferably in the evening after washing your hair. Massage gently into the scalp and allow it to dry fully before sleeping. For best results, use consistently every day. Our 3-month bundles include a dermastamp and scalp massager to support absorption and scalp health as part of your routine.

RU58841 is a non-steroidal anti-androgen compound originally developed in the 1980s for treating androgen-dependent conditions. It works by binding to androgen receptors in hair follicles, blocking DHT (dihydrotestosterone) from attaching and miniaturising the follicle. Unlike oral anti-androgens such as finasteride, RU58841 is applied topically to the scalp, meaning it targets hair follicles directly without significant systemic absorption.

RU58841 and Finasteride work differently. Finasteride is an oral 5-alpha reductase inhibitor that reduces DHT production systemically throughout the body. RU58841 is a topical androgen receptor blocker that competes with DHT at the follicle level without reducing overall DHT levels. Some users prefer RU58841 because it does not affect systemic hormone levels.

The most commonly reported side effects from topical RU58841 use include mild scalp irritation, dryness, or redness at the application site. Because RU58841 is applied topically rather than taken orally, systemic side effects are considered less likely than with oral anti-androgens like finasteride. However, individual responses vary. If you experience persistent irritation or any unexpected symptoms, discontinue use and consult a healthcare professional.

Yes. We offer a 90-Day Growth Guarantee. If you complete the full 90-day protocol as directed and do not see any improvement, we will refund your purchase. The guarantee requires progress photos taken at days 0, 30, 60, and 90 to verify consistent use. Full details are available in our refund policy.

Store your RU58841 or RUstim+ bottles in a cool, dark place away from direct sunlight. For long-term storage, refrigeration is recommended to maintain compound stability. Unopened bottles can be stored in the fridge for up to 12 months. Once opened, use within 30 days and keep at room temperature or refrigerated.
