Quick Take

A social media post claims that crushed aspirin in shampoo can treat dandruff. Our fact check reveals that this claim is half true.

The Claim

According to an Instagram post, “crushing aspirin tablets, mixing them with shampoo, and applying the mixture to the scalp can eliminate dandruff and leave your scalp flake-free.”

Fact Check

Does aspirin help reduce dandruff?

Partially true. Aspirin contains acetylsalicylic acid, which is chemically related to salicylic acid, a known ingredient in dandruff shampoos. Salicylic acid helps exfoliate the scalp, removing dead skin cells and flakes, which may temporarily reduce the appearance of dandruff. When crushed and mixed with shampoo, aspirin can mimic some of these exfoliating effects. Anecdotal reports suggest that this remedy may help reduce flakiness in mild cases.

However, acetylsalicylic acid in aspirin is not specifically formulated to target the yeast Malassezia, a key factor in causing dandruff. This limits its efficacy compared to specialised products.

Apart from this, we have also seen claims like, eating aspirin daily can help you survive a heart attack. However, this isn’t true.

Is aspirin a reliable solution for dandruff?

Not entirely. When applied to the scalp, salicylic acid can help remove dead skin cells, reducing dandruff flakes and itching. However, while this may offer temporary relief, it’s important to note that aspirin is not a dedicated dandruff treatment.

For a more comprehensive and long-lasting solution, medicated shampoos are the preferred choice. These shampoos, formulated with active ingredients like zinc pyrithione, selenium sulfide, ketoconazole, or salicylic acid, are specifically designed to target the underlying causes of dandruff, such as inflammation and fungal overgrowth. These ingredients work in various ways to inhibit fungal growth, reduce inflammation, and regulate the scalp’s natural balance.

Unlike aspirin, which lacks substantial scientific evidence supporting its efficacy for dandruff treatment, medicated shampoos are rigorously tested and proven to be safe and effective. By using a medicated shampoo regularly, you can effectively manage dandruff and prevent future outbreaks.

We reached out to Dr Rashi Soni, Co-founder and Consulting Dermatologist, Aesthetician, and Hair Transplant Surgeon at Rashi Hospital in Mumbai, for her expertise on aspirin for dandruff. She says, “While this ingredient is found in some medicated shampoos, using crushed aspirin as a DIY remedy might not be the most reliable approach. It’s hard to ensure proper concentration or consistent results at home. Instead, I recommend choosing an over-the-counter anti-dandruff shampoo that contains ingredients like salicylic acid, zinc pyrithione, or ketoconazole. These are specifically formulated to target dandruff effectively and safely. Remember, persistent dandruff could signal an underlying condition, so consulting a dermatologist is always a good idea.”

We also got in touch with Dr Ekansh Shekhar, Dermatologist, Cosmetologist, Trichologist, and Aesthetic Medicine Consultant in Lucknow, for his opinion on aspirin for treating dandruff. He states, “Aspirin’s active ingredient, salicylic acid, does have exfoliating properties that can help manage dandruff by loosening flakes. However, I wouldn’t recommend relying on crushed aspirin as a regular treatment. The concentration may be uneven, and it’s not designed for use on the scalp. For better and safer results, opt for shampoos specifically created for dandruff, as these contain clinically tested ingredients like ketoconazole or selenium sulphide. If your dandruff persists despite these treatments, it’s worth consulting a dermatologist to rule out conditions like seborrhoeic dermatitis or scalp psoriasis.”

Previously, we have also debunked a claim which suggests aspirin can prevent Alzheimer’s disease. However, this lacks substantial evidence from the medical community.

Is it safe to use aspirin on the scalp?

In most cases, yes, but you should exercise caution. One should dissolve crushed aspirin thoroughly in shampoo to prevent irritation. Sensitive scalps may react with dryness, redness, or itchiness. Children and people with salicylate allergies should avoid aspirin. Always perform a patch test before use and avoid overuse. For persistent dandruff, consult a dermatologist.

Can aspirin replace medicated shampoos?

No, medicated shampoos remain the best option for treating dandruff. While aspirin may offer mild, short-term benefits, it lacks the specialised antifungal and anti-inflammatory properties of products like ketoconazole or zinc pyrithione. These ingredients target the root causes of dandruff, such as fungal overgrowth and excessive scalp cell turnover, providing long-term relief.

The claim that crushed aspirin in shampoo can treat dandruff is half true. While it may offer some temporary relief by reducing flakiness, it is not a comprehensive or reliable solution. For better results, opt for dermatologist-approved anti-dandruff shampoos designed to treat both the symptoms and causes of dandruff.
