When Adam Macciocchi-Lancia noticed his hair was thinning, he decided to do whatever it took to reverse the problem.
The then 27-year-old artist from Toronto, Canada worried that a receding hairline would make him appear far older than what he was and ruin his dating life.
So, he booked an appointment with a hair-loss specialist and asked whether he would be eligible for a hair transplant.
But, the surprising answer he received was that the surgical procedure was unnecessary.
Instead, all he needed was a daily tablet that cost less than £1. The drug, called finasteride, or the branded Propecia, is taken by millions of men with hair loss, including President Donald Trump.
And, as the doctor explained to Adam, finasteride works wonders. According to studies, more than four in five men who take finasteride stop losing their hair.
Nearly three in five see their hair begin to grow back, often within months.
‘I was told the tablets would be as good if not better than a hair transplant,’ says Adam. ‘And there were apparently very few side effects.’

Adam was informed that, in less than one per cent of cases, finasteride patients experienced low mood and erectile dysfunction.
‘But the doctor said, if these symptoms happened, I could just stop taking the pills and they would go away,’ he says.
‘So it wasn’t something I was worried about at all.’
However, as Adam soon found out, this is not always the case.
Because, soon after beginning the treatment, Adam developed a debilitating series of symptoms that plagued his life for years – even after he stopped taking the pills.
These long-lasting problems, which Adam says destroyed his life, have been recorded in thousands of men who take finasteride for hair loss. It even has a name: Post-finasteride syndrome.
Where persistent physical and mental adverse reactions take place both during treatment and after men stop taking the medication.
Tragically, there are no approved treatments, meaning many men live with these symptoms, which include depression, insomnia, low libido and erectile dysfunction, indefinitely.
However, nearly a decade after he first began taking finasteride, Adam, now 36, believes he has found a cure – and wants to share it with others afflicted with the terrible condition in order to help them turn their lives around.
Finasteride works by blocking the conversion of the male hormone testosterone into the adrogen dihydrotestosterone, or DHT. High levels of DHT are believed to lead to hair loss by shrinking follicles on the scalp.
It was originally developed, and taken at higher doses, to treat having an enlarged prostate. Researchers then noticed that prostate patients taking the tablets experienced hair regrowth, and trials were launched which involved giving lower doses to treat hair loss.

Not only did these trials prove that finasteride was highly effective, they also concluded that the tablet was safe. Fewer than four per cent of participants experienced temporary side effects including mental health problems and erectile dysfunction.
Unsurprisingly, given more than six million men in the UK alone have male pattern baldness, finasteride was a blockbuster success from its relaunch as a treatment for hair loss in 1997, quickly becoming one of the most popular drugs in the world.
However, as far back as 2011, the drug company behind finasteride, Merck & Co, have been aware of severe side effects linked to the drug including suicidal thoughts.
In 2021, Reuters news agency revealed it had obtained US court documents which show that US health watchdogs had received more than 700 reports of suicide and suicidal thoughts linked to the drug since 2011.
These included at least 100 reported suicides. The documents also revealed Merck & Co had paid about £3.5million to settle lawsuits brought by people claiming to suffer persistent side effects.
In court, Merck denied the drug caused problems with sexual function after men stopped taking it, and links to mental illness. The claims were settled without admission of liability.
Last year, the UK medical safety watchdog, the Medicines and Healthcare products Regulatory Agency (MHRA), concluded that packs of finasteride should include a patient alert card that warned of the risks of post-finasteride syndrome.
The MHRA said it had received nearly 300 reports of depressed mood disorder, suicidal and self-injuries behaviours linked to the pill. It also identified more than 400 cases linked to sexual dysfunction.
However, none of this was known to Adam when he began taking the tablets.
He started taking finasteride in September 2016 and within two months, he says things started going downhill.
He began to experience dark thoughts about suicide, which he’d never had before. ‘I was just hit with this awful depression,’ says Adam, who is visually impaired.
‘I couldn’t get out of bed, I couldn’t hold a conversation, I couldn’t do anything. I told my parents and, by the third month, came off the pills. But nothing changed.
‘Instead, it was around then that I developed erectile dysfunction. I felt like killing myself all the time. It was like I’d lost my soul.’
At the same time, Adam also developed brain fog – which made it impossible for him to think clearly – he also developed exercise intolerance, meaning that any physical activity worsened his symptoms.
Adam repeatedly sought medical help. First, at his local hospital, then with the specialist who had prescribed him the finasteride.
Each time, he was brushed off. ‘I was told these issues were all in my head,’ says Adam. ‘The doctors said that it was impossible that finasteride had caused these issues. They said it was completely safe.’
Adam’s condition was so severe that he was unable to work and he lost his job at a construction firm that he did alongside his art.
Over the years, he tried a number of experimental treatments – including painful injections into his penis – but nothing worked.

Adam listened to a podcast which described how magic mushrooms could cure severe bouts of depression
Then, in late 2019, Adam listened to a podcast which described how magic mushrooms could cure severe bouts of depression.
The hallucinogenic fungus contains a compound called psilocybin which has been shown in studies to help with a number of mental health issues such as Post-traumatic stress disorder and Obsessive-compulsive disorder.
And while it is illegal to buy magic mushrooms in Canada – as it is in the UK – Adam decided that it was worth trying seeing if the drug could help improve his Post-finasteride syndrome.
‘I had nothing to lose,’ he says. ‘I was willing to try anything to break free of this condition.’
Adam took three grams of magic mushrooms – a high dose capable of triggering intense hallucinations – along with a friend.
‘We went for a walk in the woods while we did them,’ he says. ‘I didn’t know what to expect.’
Astonishingly, Adam says he noticed an immediate difference, saying: ‘When the mushrooms kicked in, it was like my brain fog disappeared.
‘I felt like myself for the first time in years, it was one of the most profound experiences of my life.’
Over the following months, Adam took mushrooms several more times. Eventually, he switched to microdosing them – this involves taking small daily doses of the drug.
‘Most of my side effects would go away when I was on them,’ he says. ‘However, I felt like I started to reach a limit to my improvement. I would get better for a week or two and then all the symptoms would return with a crash.
‘And no matter what I did, the erectile dysfunction was still just as bad as before.’
So, in 2023, Adam decided to try an even more intensive therapy: The potent psychedelic drink ayahuasca.
The illegal beverage, first used by Amazonian tribes, is so strong that it can trigger mental health problems in some people who take it. It can even be deadly.
However, this did not put off Adam, who believed it was his only hope of curing himself.
‘I went to see a Shaman in Ontario,’ Adam says. ‘After I drank the ayahuasca I started hallucinating.
‘When I came to, I knew that the crippling depression was gone.’
Experts warn that patients who experiment with illegal drugs could be putting themselves in danger.
‘I’ve never heard of anything like this before and it’s not a good idea to try illegal drugs in this way,’ says Dr David Fenton, a Harley Street consultant dermatologist.
‘These drugs have many side effects and often are not safe.’
A year-and-a-half on, Adam’s condition has continued to improve. He has been able to return to his work as an artist and he regularly exercises.
He is now side effect free with the exception of the erectile dysfunction. However, Adam says his erections continue to improve slowly and he is hopeful for the future.
‘I finally feel like I’ve got my soul back,’ he says.
‘I’ve done so much work on myself, and now I feel open and ready to finally enjoy life again.’
Not only can this be illegal, it can also be dangerous. Both magic mushrooms and ayahuasca have been linked to mental health issues and deaths.
Any new treatment should always be discussed first with a medical professional.
