Can paracetamol cause hair loss?

Hair loss shouldn't be such a taboo topic, especially since it's a widespread issue that affects thousands of men around the world. Instead of talking about it, most people would just give up and keep quiet or constantly search for terms like 'Does Paracetamol Cause Hair Loss' on the web. But the reality is that there's no need to feel ashamed or embarrassed. There are heaps of people dealing with the same situation, and the increase in searches for 'Hair Loss Causes' only proves this. Many people who look for answers end up on websites aimed at sales or unmoderated forums with no moderation. With all options such as this, wouldn't it be better to get real medical advice from a doctor?

Currently, there is no strong scientific evidence linking paracetamol directly to hair loss. The medication is widely prescribed for pain relief, and adverse effects related to hair loss are not commonly reported in medical literature [1].

However, some cases of hair shedding may be indirectly related to paracetamol use under specific circumstances.

Certain medications, particularly those that affect hormone levels or the immune system, can contribute to drug-induced alopecia. While paracetamol is not typically listed as a common cause of medication-related hair loss, prolonged or excessive use of the drug could theoretically contribute to hair thinning due to liver toxicity or other side effects [2].

Paracetamol is metabolised in the liver. High doses or long-term use can lead to liver damage, which may disrupt the body's ability to process essential nutrients such as biotin and iron—both of which play a role in hair health [3]. Individuals with chronic liver disease may experience hair thinning as a symptom of underlying nutritional deficiencies rather than the direct effect of paracetamol itself.

Although rare, some people may experience allergic reactions or hypersensitivity to paracetamol, which can trigger conditions such as telogen effluvium—a temporary form of hair loss caused by physiological stress [4]. If you notice excessive hair shedding after taking paracetamol, consult a healthcare professional.

If you are experiencing unexplained hair loss, it may be due to other factors rather than paracetamol use, including:

• Genetic predisposition (male or female pattern baldness)
• Hormonal imbalances (thyroid disorders, pregnancy, menopause)
• Nutritional deficiencies (iron, biotin, vitamin D)
• Stress or illness (physical or emotional stress can trigger temporary hair shedding)
• Other medications (such as chemotherapy drugs, beta-blockers, or retinoids)

If you suspect your hair loss is linked to paracetamol or any other medication, speak to a healthcare professional. They can help determine the underlying cause and recommend appropriate treatments, whether it be adjusting your medication, improving your nutrition, or exploring targeted hair regrowth therapies.
