Excellent product and service
I have been using the Unthin spray for almost 2 years and the results have been great. I have seen no further recession in my hair, and the Unthin team has been extremely helpful in answering my questions and modifying my subscription to suit my specific needs.

Thank you for the fantastic feedback - really glad to hear two years in, the recession has held steady, and that the team's been able to flex your subscription to suit you along the way. Appreciate you taking the time to share this.

Does exactly what it promises
Ive been using Unthin for 4 months and really happy with the results. Much thicker hair in the areas it was thinning. Very easy to use and I actually really like the slightly matte texture it gives your hair, I don’t bother with hair gel anymore.
Very good stuff 👍🏻

Unthin Is The Real Deal!
Been using this product for just over 6 weeks after my barber recommended it. He showed me results from himself and another of his friends whom has been using Unthin for several months also. I was still sceptical as I've had hair loss around my crown and temple for a few years now. To see the progress that's been made is such a short time is unheard of. To any sceptics out there, give this product a go. Stick with it and watch your confidence grow as your hair grows back!

Thank you for such a great write-up - it really means a lot that your barber's recommendation paid off, and even more that you're now seeing results yourself after being sceptical going in. Encouraging other sceptics to give it a proper go is exactly the kind of endorsement we're grateful for. Thanks for sharing.

Worth a try
So, despite initially being sceptical, I did a little research and thought I’d give Unthin a go.
I wasn’t bald, however, was noticing (age related I’m sure) that my hair was thinning, scalp more visible, and figured I should do something before it became an issue.
I used Unthin as instructed and admittedly the results weren’t immediate, which would’ve been nice, though with continued use (6 months now) I’m genuinely noticing a difference.
I’m not a ‘before and after’ kinda guy but I’m now finding myself leaving a review and recommending Unthin to my friends.
If it’s something you’ve noticed give Unthin a try, it’s cheaper and more convincing than the alternative trip to Turkey some of my pals have made.
Thanks guys!

Thank you for such a thoughtful and honest review — it really means a lot to us.
We completely understand the initial scepticism, especially when results take time. But you stuck with it, and we’re so pleased to hear that after 6 months, you’re genuinely seeing the difference. That’s exactly how Unthin is designed to work — gradual, consistent improvement that adds up over time.
We love that you’ve gone from “not a before and after kind of guy” to recommending us to friends — that says everything! And yes, we’re definitely here to be a smarter, more affordable alternative to a trip to Turkey.
Thanks again for the support — we’re glad to be part of your hair journey!

I started using Unthin after a recommendation from a friend who has had great success with the product.
I’ve now been on the spray for 5 months and am stunned at how much hair I have had return. It’s really filled out my crown and top of my head.
If you are even half tempted I would try unthin. There is nothing to lose I thought I would eventually end up having a transplant, but don’t think that will be the case now!

It’s amazing what 5 months of consistency can do, and we’re especially glad to hear that your crown and top have filled out so noticeably. Stories like yours are exactly why we do what we do.
You’re absolutely right — for anyone on the fence, there really is nothing to lose by starting, and as you’ve shown, potentially a lot to gain.

We're genuinely sorry to read your review and disappointed that you felt the need to share such feedback, especially given the extensive communication we provided throughout the process.
To clarify the timeline:
You placed your order on 20.04.2025, and on the same day, you received both your order confirmation and a link to complete your medical questionnaire. We then sent 7 follow-up emails and 3 text message reminders to prompt you to complete this essential step, which is required, by law, before we can dispense any treatment.
You emailed us late on Saturday 26.04.2025 at 23:55, and we responded the next morning on Sunday 27.04.2025 at 11:09, once again advising you to complete the medical questionnaire form. You emailed again on 30.04.2025, and we responded within 5 minutes, reiterating the same guidance.
We truly feel we went above and beyond to support you and help move things forward, but unfortunately, this wasn't reflected in your experience.
Your account has now been closed, order cancelled and refund issued. We sincerely wish you the best on your journey to achieving thicker, fuller hair.
Best regards,

These guys wont let you cancel your subscription. You have to email them and they don't respond. You can pause the sub but then when it unpauses you're paying again. Scam.

Life Changing.
I began using Unthin after recommendation from a friend in September, and the results are far better than I could ever have imagined. I’ve noticed regrowth in all applied areas (crown, corners and centre), i’ve got my confidence back, and all my friends and family have noticed the difference too. I cannot thank the unthin team enough.

Great Product (it works) and Great Customer Service
I've been using Unthin for about seven weeks now, and I'm genuinely impressed with the results. Despite what other reviews might say, this product definitely works! I've noticed new hair growth, especially on my temples and crown, with lots of short hairs coming through.
Ignore the 1-star reviews—this does work, and it’s working for me. You’re never going to see results after just a few weeks; you have to give it at least three months, as they say. That being said, I am seeing results after just seven weeks. A lot of very fine hairs are appearing where before there were none, and my hair already feels slightly thicker. But I have been religious with it—every morning and night without fail.
The customer service at Unthin is fantastic, and the product itself lasts a long time.
Pro tips:
Cut down (or better still give up!) on smoking and heavy drinking, as these can impact the results.
Eat a healthy diet to maximise effectiveness.
Be consistent—don’t miss applications, morning and night.
Overall, my experience has been really positive, and I’m looking forward to seeing even more progress!

Hey I’m a barber from Manchester with numerous shops. I’ve been using unthin now for 9 Months and it’s really worked! My thinning spots on my temple have come back to life.
I had a hair transplant in 2017 and it was a success. I noticed 2023 my hair started to thin again, when wet you could see my scalp.
Fast forward December 2024 and my hair is so thick! You can’t see any scalp areas and my hairline is solid. I use the Plus version.
Highly recommend it!

Great product highly recommended.
I have been using this product since March 2024 and it’s now November. I am honestly surprised how well it’s worked. I have used the spray with the micro needle roller. I have had new growth on my crown and my hairline has started filling out at the slides.
Great product highly recommended.
I was considering getting a hair transplant but am going to stay with his a bit longer as it working for me.

9 months in, very impressed!
After 9 months my hair continues to look thicker and has much more ‘body’. I use it morning and evening as advised. A developing bald spot has basically gone, I think it must be about like my hair was 20 years ago.
I don’t know if it works for everyone, but it works for me! :-)
