Just a false product
Just a false product. The contents have no ingredients in to promote hair growth. Scam by 4*men in Lincoln. Don't sign up to this fake product. Save your money and not give it to these scammers

Caused scalp irritation
Product caused quite severe scalp irritation for me when used as directed. Emailed Unthin who responded quick and suggested taking antihistamines too and if symptoms persisted then stop use. Antihistamines didn’t work so I stopped use and was not able to use long enough to determine whether it is effective (which Unthin do say can take a number of months). Tried reducing dosage but was still causing irritation so had to stop using after just over a month. Think the irritation may be down to topical finasteride needing propylene glycol in order to be effective. Shame as a had high hopes for the product and didn’t want to take finasteride pills.
I persevered and it is working!!
I'm in my late fifties and have long, curly hair which I started to notice was getting a bit thinner on top so I started using Unthin 10 months ago. It is only in the last month that I have started to notice a difference and the hair on top of my head is definitely thickening up so it is working! People have commented and my confidence and self-esteem has improved as a result. Persevere with it for at least 9 months - it is working for me!! 😁
I was sceptical but I am a convert.

I'm 50 and have been using Unthin for 9 months.
My forehead was thinning but now is thicker and my hairline isnt receding as much. In fact, I've got hair where I haven't had any for years!!
Be patient, but this works!
Highly recommended

As a 60 year old man
As a 60 year old man, I had accepted my hair was getting thinner. I was introduced to Unthin by a friend. I was sceptical initially, but decided to give it a go. After 2 months, my wife commented first that there was a noticeable improvement, I have now been using for 6 months and honestly, my hair definitely is thicker and healthier. I will continue using Unthin.

I had a hair transplant about 5 years…
I had a hair transplant about 5 years ago and recently started noticing my hair was thining again. I started using Unthin about 5 months ago and my hair has never looked thicker. Nothing happened for the first couple of months, then month after month my hair density has improved and keeps on improving.

It does what it says on the tin
I have been using this product now for seven months. The product itself is very easy to use. Brush your teeth, squirt your head, it has just become part of my routine.
I didn’t see any immediate effect but after about three months or so, I noticed my existing hair had become darker and thicker. People started to comment, which to be honest I found quite embarrassing. Very small thin hairs started to grow. Initially I wasn’t sure if I was imaging them or maybe they were there before but I hadn’t noticed them. Now however they are fully grown to length (my hair is short no5 on top). They are still very thin and don’t really have any colour but I’m hoping over time they will begin to thicken and once again get some colour.
I’m not sure if this is the best product on the market as there are so many other types of product claiming to do similar. But Unthin has definitely changed my hair loss to hair growth. My only regret is not finding it earlier.

Noticeable thicker hair after 3 months
Noticeable thicker hair after three months. Now over six months in and it continues to impress. Hoping after one year it’ll be as it was 20 years ago! Barber noticed and commented on the thickening after three months. Wish I had taken pictures before using. Would recommended.

I have found using Unthin very easy
I have found using Unthin very easy, once in the morning and once on an evening, over the first 3 months there was not much difference but now after 6 months you can definitely see a difference and I will continue to use Unthin for the next 6 months to see if the results continue.

So I started my unthin journey back in…November
So I started my unthin journey back in November of last year obviously these things are not going to work overnight but unthin are very honest they do actually tell you that you wont notice much until around the 1-3 month mark I've been using unthin now for 7 months and have noticed hair growth not a great deal but definitely more than 6 months plus ago to the thinning parts of my hair I've been applying it to.

Was very dubious but gave it a go.
Was very dubious but gave it a go.
What hair I had left felt thicker, did notice some regrowth at back of my head after 3-4 months. Unfortunately due to a health issue (not related), I had to temporarily stop treatment, my hair was noticeably thinner within weeks. I have just recently restarted so finger crossed for another improvement

Doesn't work - avoid
I've been using it for 4 months now and my hair is thinner - not thicker.
I emailed them and say to keep using it. But considering it doesn't seem to be working, and I sent them photos to show them, for them to say "keep giving us money and it might work at some stage" is ridiculous.
Definition of insanity.

Amazing hair growth
I started using Unthin last November and 7 months on I am seeing amazing results. My hair is visibly thicker and I have a lot more growth, in areas that were previously thinning. My hair loss has stopped.
My barber is amazed at my results, he's been cutting my hair for a few years and he told he's never seen my hair so thick before.
Unthin definitely works! I will continue to use this product as not only is my hair growing but so is my confidence. Thank you Unthin!

Working well so far
I started using Unthin spray in November. Seven months in and definitely noticing a little bit of regrowth, and that my hair is much thicker around that area. Price is a little steep at £40 per month but I’ll continue to use as long as I’m seeing results.

The product is working well
The product is working well! I’ve used it for 7 months and my bald spot on the crown is a 1/3 of the size it was. There’s steady improvement each month and I’m hoping after a years use it’ll be completely gone. It’s worked a bit slower than what I was lead to believe but I’m still happy with the product.

I was more than a little sceptical…
I was more than a little sceptical about any hair loss treatment but gave this a go, what did I have to lose? Other than hair!
Been round 6 months now and I definitely have more coverage. The every growing thin patch on top has stopped and it looks like the start of reversing.
I will definitely use this for another 6 months and check my progress.
The side affects are minimal in my case which was a concern initially. I just wish it was about 10 years ago.
