Five Common Misconceptions About Hair Loss
[Case] Mr. Yang, aged 30, noticed hair loss early and, though mild, decided not to visit a doctor. He began researching hair loss online. Naturally, many “product promoters” claimed their products worked miracles, changing identities to self-praise. Unwary, Mr. Yang ordered a “miracle” hair growth product advertised as effective by many. Following instructions, he applied it three times daily for a week—only to end up in hospital a week later because his hair loss hadn’t stopped, and his scalp had become red and itchy.
Dermatologists point out that many hair loss patients fall into common traps due to limited knowledge and reluctance or embarrassment to consult doctors—leading to avoidable complications from improper medication.
Misconception One: Hair loss equals kidney deficiency
Doctor’s Explanation: Many male hair loss patients believe hair loss is due to kidney deficiency. They rush to buy kidney-tonifying herbs upon noticing hair thinning. While kidney deficiency can cause hair loss in traditional Chinese medicine diagnosis, not all hair loss stems from this. Blindly taking tonics helps nothing. Diagnosis by a doctor is essential to identify the root cause and treat accordingly.
Misconception Two: Self-diagnosis and self-treatment
Doctor’s Explanation: Some people, seeking convenience or influenced by advertisements, cannot distinguish among the countless oral and topical medications available. They buy randomly based on recommendations. Some products have no real therapeutic effect, delaying proper treatment and worsening hair loss. Experts emphasize there is currently no drug that can fully cure hair loss. However, timely intervention can significantly reduce severity.
Misconception Three: Increasing or decreasing shampoo frequency
Doctor’s Explanation: Is hair loss caused by washing hair? Many hair loss sufferers think so. Some increase shampoo frequency believing oily scalp causes hair loss. Doctors note that washing hair every 3–4 days in winter and every 2–3 days in summer is normal. Washing too frequently increases follicle irritation, while infrequent washing promotes Malassezia yeast growth, worsening hair loss.
Misconception Four: Applying garlic, ginger, alcohol, etc.
Doctor’s Explanation: The idea that applying garlic, ginger, or alcohol stimulates regrowth is widespread. However, excessive application of irritating substances damages the scalp, triggers inflammation, and worsens hair loss.
Misconception Five: Wearing hats to hide hair loss
Doctor’s Explanation: Hair loss makes people feel their appearance is ruined, so some wear hats constantly. Experts warn that wearing hats compresses scalp blood vessels, impairing circulation. In hot seasons, the scalp and follicles trapped inside hats suffer from poor ventilation, accelerating hair loss.
