You must stick at it
Hasn't been as quick progress as I thought it would be. But do think after 6 months iv seen a little bit of progress now. You really have to give it 6 to 9 months before judging. It's not a quick fix so be willing to go the long haul. Hope to see more regrowth soon.

Simple and effective treatment for balding and thinning hair
I have been using Unthin for 7 months and have noticed a significant change in the growth of my hair over this time. I had noticed some thinning and balding of my crown and hairline over the past year, and after becoming quite self conscious about it, decided to do something about it.
Over the course of the last few months, I’ve noticed that my balding crown has almost completely recovered, my hair has stopped falling out and I am started to see an improvement in my overall hairline, with smaller hairs sprouting which have given my hairline a more revived look.
I didn’t notice anything after the first 3 or so months, but there became a point where I noticed that my hair has become thicker, had stopped shedding and just generally looked healthier. It’s important to stick with it, even if you don’t see any visual results in the first few months.
The spray is easy to use and takes no time at all. Just 6-8 sprays to washed, dry hair in the morning and evening is enough to get you on your way. I have also started using a derma roller to help absorb the spray into my hair follicles more quickly.
I’ll continue to use Unthin as it’s now become a part of my daily routine and I’m excited to see how much further the results will develop over time.

Tremendous
Great product, over time it has increased my hair thickness, growth and confidence. 7 months in and my hair's doing wonderfully. Pain free application with no side effects.

I must admit i was a bit sceptical about subscribing to unthin, but I must say i have been happy with the product.
My wife is a hairdresser and cuts my hair said she has genuinely noticed a regrowth coming through.
I’m not saying it has covered a balding patch that i have, but it is definitely less noticeable.
I have been using it for 6 months now.

Unthin has been great for me
Unthin has been great for me. I've noticed hair regrowth and stopping thinning (even though I admittedly am not good at managing twice daily, but do manage once). didn't get any side effects from topical finasteride in the same way as I did from the pills I was taking before. My hair does tend to get a little greasy after applying, which isn't an issue when I apply before bed and shower in the morning.

Unthin Hair Treatment
I have been extremely impressed with Unthin. The small spray treatment bottles last for the entire month, when used as directed. They have always arrived in time for continued use. Regardless of bank holidays or Christmas.
My hair has not shed at all, which I feared may have been the case, upon first using Unthin. My hair has grown back where much of it had been lost. Though not as thickly as I would have liked in an ideal world. However it is enough to make me feel confident in being me. Takes away all the worry of hair loss, day to day. I can get on with my life.

This treatment just works!
This treatment has worked much better than I could expected. 6 months in and my hair is much stronger all over with significant re-growth too. I think having both active ingredients in one topical application works perfectly

Happy with progress, so far.
Been using this since October 2021. Noticed slight regrowth and am happy with the progress so far. The solution can discolour pillow cases over time but this does wash out.

Hair is definitely thicker and fuller and has stopped hair falling out, No regrowth on hairline but overall very happy with progress

Slower Progress Than I would Have Hoped
I've been using Unthin for around 8 months now and have noticed progress and growth. For those wondering the liquid itself is almost fragrance free and no one will notice, it does leave a slight shine (similar to being slightly sweaty). Just take note that you may not fully revert hair loss in 6 months, I'm sticking with it as progress is still being made.

Steady progress
After 3-4 months I noticed increasingly more volume of hair near my crown. After almost a year my hair is as thick as it’s ever been. I was very sceptical before hand but I’m delighted with myself that I decided to be consistent and give this a go!

Overall I have seen a improvement in my thickness of my hair.
I wasn’t bothered that I was thin and was losing my hair. However, I saw the advertisement and looked interesting.
So I have been using for 8 months now and have seen growth.
When your hair gets longer, I find my hair gets very greasy after applying the solution twice. So your have to shower every day.
Overall happy so far

Good Product
Seems like a genuine product so far - granted, I need to be more disciplined with my daily application but even with my less than strict use, I have seen improvements.

Six months in now and hair is thicker and seems to be improving. Went slow after month 4 hoping it picks up again in next 6 months.
