If you have lost your sense of smell, it is completely understandable to look online for answers. Searches for smell loss cures often lead people to social media, where advice, hacks, and quick fixes are shared widely. Some sound convincing. Others promise fast results.
The difficulty is that much of this information is misleading. It can leave people confused, discouraged, or feeling as though they have failed when something does not work for them.
This article explains why so many online smell loss cures appear to work, how different types of smell loss behave, and what the science actually supports.
Two types of smell loss after Covid
Covid-related smell loss generally falls into two groups. Understanding which type you have helps explain why quick fixes are so common online.
Short-term smell loss
Around 9 out of 10 people recover their sense of smell within two to three weeks.
This happens because inflammation high up in the nasal cavity temporarily blocks access to the olfactory epithelium, the small area responsible for detecting smells. This blockage sits behind the bridge of the nose, above the area where congestion is usually felt. Many people describe their nose as feeling dry or unusually clear.
As the inflammation settles, smell returns quickly and fully.
Persistent smell loss
For a smaller group of people, the virus damages the olfactory nerve cells themselves. These nerves can repair, but it is a slow process. Recovery may take many months and sometimes up to two years.
On day one of smell loss, there is no way to know which group you are in. Only time tells. There is nothing you can do early on to prevent persistent smell loss or force a quicker recovery.
Why so many smell loss cures appear to work
Smell loss can be deeply distressing, particularly at the start. Many people turn to social media looking for solutions that doctors cannot immediately offer.
The people most likely to post dramatic recovery stories are usually those with short-term smell loss. Their sense of smell was already going to return quickly.
If someone tries a hack, for example the burnt orange trick, and their smell returns the same day, the brain naturally links the two events. That “cure” then gets shared widely, often with the genuine intention of helping others.
This is how misinformation spreads. Recovery would have happened anyway, but the timing makes the intervention look effective.
When misinformation causes harm
Many popular smell loss cures shared online are physically harmless. The real problem is false hope.
When people with persistent smell loss try the same tricks and see no improvement, they may feel discouraged or blame themselves. Some stop pursuing approaches that actually have evidence behind them.
Posts titled “How to cure smell loss” or “One simple trick doctors won’t tell you” are also often designed to generate clicks and income, rather than to support people living with long-term symptoms.
What does the science say?
There is currently no scientific explanation or evidence to support popular online fixes such as burnt oranges or chiropractic head movements.
Some supplements, including vitamin A drops, alpha lipoic acid, and zinc, have been researched for smell loss. The evidence so far is weak and inconsistent. This is why doctors do not routinely recommend them. If you choose to try supplements, follow dosage instructions carefully and avoid taking multiple products without advice.
At present, there is one intervention for smell loss that has consistent scientific support.
Smell training: the evidence-based option
Smell training is recommended by the British Rhinological Society and ENT UK for people with olfactory loss.
It involves repeated, structured exposure to a small set of scents over time. The aim is not the smell itself, but encouraging the brain to rebuild and strengthen smell pathways.

Smell training is not a quick fix
Smell training is more like rehabilitation after a stroke than a home remedy. Progress is usually slow and gradual.
Most people need to practise consistently for at least four months before noticing meaningful changes. Improvement often comes in small steps rather than sudden breakthroughs.
If someone says smell training restored their smell in two weeks, they almost certainly had short-term smell loss. That does not mean smell training failed for you. It means your situation is different.
Key Takeaway
Many popular smell loss cures shared on social media reflect natural recovery rather than real treatment. If a cure sounds fast, simple, or guaranteed, it is unlikely to be evidence-based. For persistent smell loss, smell training remains the most scientifically supported way to aid recovery, even though it takes time and patience.
