This study observed that among 120 patients recovering from COVID-19, severe diffuse hairloss typically began less than two months post-infection, with the majority of patients experiencing a severe degree of hairloss and positive hair pull tests, often alongside vitamin D deficiency.
COVID and COVID vaccination can trigger hairloss, primarily telogen effluvium, due to stress and immune system activation. Proper diagnosis and addressing factors like nutrition and stress are crucial for recovery.
Finasteride users may have an increased risk of depression, anxiety, and suicidal thoughts, though some attribute these issues to hairloss itself. The link between finasteride and mental health effects is debated, with varying user experiences.
A 19-year-old in France is experiencing hairloss after COVID-19 and is using Minoxidil, considering Finasteride but facing challenges in obtaining it. Users discuss Minoxidil's effectiveness, potential issues like crystallization, and alternative products like Foligain.
A 28-year-old male experienced hairloss after COVID-19 and used Minoxidil with initial success, but later faced shedding again. He started Finasteride in February 2025, noticing improvements, but recent shedding has caused concern; his regimen includes Minoxidil, microneedling, ketoconazole shampoo, red light therapy, supplements, and a healthy lifestyle.
The user is experiencing sudden hairloss and is considering micro-needling, low-level light therapy, iron supplements, folihair, and Omega 3. They are hesitant to start finasteride, suspecting the hairloss might be due to telogen effluvium from a past COVID-19 infection.
Can ketoconazole make hairloss worse before it makes it better?No study shows a minoxidil-style "shed" with ketoconazole shampoo. The label does list increased hair loss (under 1% in trials) and alopecia among reported side effects, so new or increased shedding is worth raising with a doctor or pharmacist.
Can a zinc deficiency directly cause hair thinning or increased shedding?Studies link low serum zinc to diffuse shedding and alopecia areata, and severe deficiency states cause hair loss that reverses when zinc is replaced. The evidence is mostly observational, the one supplementation study was small and uncontrolled, and zinc is not a treatment for pattern hair loss.
How can I stop hairloss related to hair transplants?Continued thinning around a transplant is usually ongoing pattern hair loss. A doctor can confirm the cause and discuss licensed treatments such as minoxidil or, for men, finasteride, which has side effects that can persist after stopping.
