    Charlie with a short buzz cut showing his thin hairline and crown before treatment

    I was bald at 32. A transplant didn't fix it. This did.

    I had a hair transplant at 28. It did nothing. I tried finasteride and got the side effects everyone is scared of, so I came off it. At 32 I found RU58841. Four years on it now, zero side effects, and the hair in the photos is mine. I made RUrestore because nobody in the UK was selling it properly: lab tested, a real price, and someone you can actually speak to about it.

    What's in the bottle?

    Glass shield, RU58841 blocking DHT

    5% RU58841

    The Shield

    The DHT blocker. Applied to the scalp, it sits on the follicle and stops DHT binding there. Read the study

    Dropper releasing a blue drop, minoxidil

    5% MINOXIDIL

    INCREASE THICKNESS

    The grower. In a 48 week trial of 393 men, 5% minoxidil gave 45% more regrowth than 2%. Read the study

    Coffee beans, caffeine

    Caffeine

    BOOST CELL METABOLISM

    Backs up the follicle. In a 6 month trial of 210 men, a 0.2% caffeine liquid did about as well as 5% minoxidil: 10.6% more growing hairs vs 11.7%. Read the study

    Fresh mint leaves, peppermint oil

    Peppermint oil

    STIMULATE BLOOD FLOW

    Wakes the scalp up. In a 4 week mouse study, 3% peppermint oil gave the strongest hair growth of the four groups, ahead of 3% minoxidil. Read the study

    Stop the leak first. Then fill the bucket.

    Cartoon: a thinning man pours minoxidil into a bucket that leaks out of a hole at the bottom
    DHT is the leak

    It is a hormone that shrinks your follicles a bit more every cycle until the hair gives up. Using Minoxidil or anything to try grow hair while you have a leak is a waste of time.

    Cartoon: a friend plugs the bucket's leak with an RU58841 cap
    RU58841 Plugs the hole

    You apply it to the scalp, it sits on the follicle and stops DHT binding, so you stop losing hair.

    Cartoon: with the leak plugged by RU58841, minoxidil fills the bucket and the man has a full head of hair
    Then fill the bucket

    Once the leak is stopped, Minoxidil pushes growth. RUstim+ has both in one bottle. plus the Caffeine and Peppermint oil, which allows for the best results.

      Once a day. Night is easiest.

    2. Step 2

      Massage your scalp first

      Use the scalp massager. Massage to increase scalp blood flow.

    3. Step 3

      Then apply 1ml

      Use 1ml on the areas that are thinning.

    4. On stamping day

      Wait 24 to 36 hours

    Who it's for?

    Male pattern hair loss is caused by DHT. If that is you, this is built for you.

    ✓Receding hairline or thinning crown

    The classic pattern: temples going back, crown thinning out.

    ✓You don't want pills

    It goes on your scalp, not in your mouth.

    ✓Already on minoxidil

    Add RU58841 5% to block DHT while minoxidil keeps pushing growth.

    ✓Had a transplant

    Transplanted hair doesn't stop the rest of your hair thinning. This is for the rest.

    Not for women who are pregnant or breastfeeding, or anyone under 18.

    What to expect.

    What to look for as you compare photos.

    1. Weeks 1 to 4

      Watch for shedding

      Note any changes in how much hair you're shedding. A short shed is normal as weak hairs make way for new ones.

    2. Weeks 4 to 12

      Look for fine hairs

      Check your photos for short, fine hairs in thinning areas.

    3. Months 3 to 6

      Check for changes in density

      Use matching photos to check how much scalp is visible.

    4. Month 6 onwards

      Keep tracking

      Compare photos in the same spot and the same light. Keep applying.

    Your 90 day roadmap.

    Start with a photo. Use it to track changes.

    1. Night 1

      Take your day 1 photo

      Same spot, same light, every time. You will forget what it looked like.

    2. Every night

      Two minutes

      1ml on the thin areas, work it in with the massager.

    3. Weeks 2 to 8

      Don't panic at a shed

      Some men get a short shed as weak hairs are replaced. Keep going.

    4. Day 30

      Compare photos

      Less in the plughole is usually the first sign.

    5. Day 90

      Day 90 photo

      Better: keep going. Not better: send both photos for your money back on your first order.

    6. Month 6 on

      Keep it

      Stop and DHT goes straight back to work. Keep applying.

    Pick your bottle.

    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.

    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.

    Questions men ask before they buy

    Is RU58841 legal in the UK?

    Yes. It is legal to buy, own and use in the UK. It is not a licensed medicine, so it is sold as a research compound and we cannot call it a treatment.

    How do I apply it?

    1ml from the dropper onto the thin areas, once a day, dry scalp. It dries in about a minute. If you stamp, wait 24 to 36 hours before the next application.

    RU58841 5% or RUstim+?

    Already on minoxidil and happy with it? RU58841 5% on its own. Want the blocker and the grower in one bottle and one job a day? RUstim+. Most first orders are RUstim+.

    When will I see something?

    Less shedding in the first month. New fine hairs by week 8 to 12. Visible density months 3 to 6. Take a day 1 photo or you will forget what it looked like.

    What are the side effects?

    Most men report none. The one worth knowing about is a racing heart in a small number of users. If you get that, stop. Some men get a short shed in weeks 2 to 8 as weak hairs are replaced. Not for women who are pregnant or breastfeeding, or anyone under 18.

    How does the 90 day guarantee work?

    First order only, one claim per household. Day 1 photo, use it daily, day 90 photo. No regrowth, full refund.

    Delivery and returns?

    UK: Royal Mail tracked, £4.97, posted the same working day if you order before 2pm, usually with you in 1 to 3 working days. EU and USA too. Unopened bottles can be returned within 14 days.

    Can I check the lab report myself?

    Yes. Go to verify.janoshik.com and enter key HMVJIB1TQX9E, Janoshik task 113894. The lab shows you the report it holds, not our copy.

    Who shouldn't buy this?

    Anyone who will not do it every day for three months. It is two minutes a day, but it is two minutes every day. If that is not you, save your money.

    Your hair back in 90 days.
    Or you don't pay.

    Start tonight. Take your day 1 photo. In 90 days you will either have new hair or your money back. Three bottles with the free dermastamp and massager is the one I would start with: £130 for RUstim+, £115 for RU58841 5%.
