I was charged for an order on the 20th March (it’s now 16th April), it never arrived. I’ve emailed customer services on several occasions and not had a response. No refund, no reply. Avoid!

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.

Wish I’d started sooner
Wish I’d started sooner! Noticeable difference in three months and then my hair continues to look thicker and fuller!! Speedy delivery and great customer service!

Best product of it's kind
I have used products similar before but unthin has been by far the best. I have been using post hair transplant and I have noticed far thicker hair on my head now . Have even recommended to friends. Customer Service also very helpful.

My partner uses Unthin
My partner uses Unthin, he has done for over a year and has 100% seen a difference. He will be continuing to subscribe moving forwards. Great product, be patient as results can take some time but worth the wait.

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! :-)

Great product. Must buy!
I've been using the product for several weeks. Although it's early days, I've started to notice and feel the process working. My hair is starting to thicken up and my confidence is growing each day. I bought the product as my hair has always been thin in texture and when it's wet, it can feel as though I've got less than what I actually have. I'd definitely encourage people to use this product. It's well worth the money and it's convenient to use on the go as its contained in a small bottle. Customer Service is great. I've built up a good rapport with the team!

I used this product for 15 months after…
I used this product for 15 months after my transplanted hair was starting to thin some years after having it done.
Applying it twice a day was a real challenge as it was greasy and you cant wash it out for 4 hours or apply the second amount for 12 hours. I had slight thickening in the crown and less hair fall when showering but nothing more than id expect from minoxidil on its own.
The big disappointment was my temples and frontal hair as it has not only thinned but I've lost hair in that area. The customer support is great and they will pause your subscription and restart it when you have surplus of treatment.
I'm giving it one more month and will probably switch to oral Fin and Minoxidil.

I have used this product for 2 years
I have used this product for 2 years - no one can say I have not given it a fair trial - and it HAS NOT made any difference whatsoever. It does not work. Do not even think about believing the photographs.
In reply to Unthin.
Your trial was £10 per month.
Your usual price was £40 per month.
I did not want to pay £40 per month for a product that I suspected would not work.
I had asked a chemist if hair loss could be reversed with chemicals and he said the best that could ever be achieved was a little fluff - but definitely not a full head of hair like you pretend. If it was that easy, no one in the world would be bald.
I bought your one month trial through 8 different email addresses and under a variety of names - check my two addresses for orders and not specific email addresses - and you will see that cards in my name were used every time.
I also ordered through family and friends.
I used your product religiously for two years with nothing to show for it.
Your photos are fake - I know it and so do you.

10/10 Definitely worth using if you’re worried about hair loss!
I started using Unthin in August 2022, and noticed a difference barely within a week. I took weekly photos to check progress and the difference was clearly visible. I was sceptical at first (probably like most people) but this product really does work. The customer service is excellent, I have no complaints and can’t fault them in anyway! Definitely worth a try if you’re worried about hair loss!

Good product
Treatment going great so far. Have seen progress within a month.

My hair is definitely thicker and there has been new growth. My wife mentioned that I look to have more hair even though I didn’t tell her I was using Unthin!

Admittedly cynical at first about whether it'd work for me but now I'm definitely seeing some additional hair growth after two full months of use! Looking forward to continuing on with the treatment and seeing further results.

Reply from Unthin
Easy to use
While the results may be slightly less noticeable compared to the pill form (not scientific and could just be me over analysing), the topical spray comes with the benefit of avoiding side effects associated with pill form. This makes it a good option for those who prioritize minimizing risks. It's also relatively easy to use and less greasy than other spray options.

Reply from Unthin
Noticeable progress in 4 months.
No need to do anything after the first order, every month a new bottle arrives on time. I've been using the spray everyday for almost 4 months and my hair has noticeably thicker look and feel around the hairline and crown. I'll be using the spray for several more months to see how well it progresses.

I've seen improvement in hair growth…
I've seen improvement in hair growth when using this product along side Hair Skin and Nail vitamins. It's been a gradual process over the last year or so but there has definitely been improvement. I've occasionally required a break from my subscription and the Unthin staff have been happy to do this and actioned it rapidly.

Seriously worth a try
I was super skeptical but following a recommendation from a friend thought I'd give it a try. After a slow start - as outlined in the guidance I lost some of the thin hairs on top so initially felt more bald - things really picked up around months 5/6 and now have considerably thicker looking hair that people have started commenting. Things have plateaued a bit recently but I'm on month 8 and committed to seeing how things look after a year.
