Background: Acute telogen effluvium is a non-scaring hair loss, usually occurs 3 months after the stressful event that causes hair shedding, and lasts up to 6 months. It can be associated with post COVID-19 infection.
Objective: To study the possible effects of COVID-19 on the hair growth cycle and the relationship between COVID-19 and acute telogen effluvium.
Patients And Methods: This is an observational cross-sectional study that had been conducted during the period from September 2020 to March 2021 years. Thirty-nine patients with post COVID-19 hair loss are confirmed by polymerase chain reaction (PCR) or antibody testing. Hair pull test was carried out to confirm the diagnosis and severity of telogen effluvium.
Results: Thirty-nine patients were evaluated; their ages ranged from 22 to 67 years with a mean and SD of 41.3 ± 11.6 years with 36 (92.3%) females and 3 (7.69%) males. All patients with a diagnosis of ATE were enrolled in this study and had a laboratory-confirmed diagnosis of prior SARS-CoV-2 infection; 15 (38.46%) patients reported mild symptoms, 24 (61.53%) patients presented with moderate disease, and no patient required hospitalization. They all experienced excessive hair loss within 2-3 months after infection. Pull tests were strongly positive (> 10-50% with a mean of 35% of pulled hair away from scalp).
Conclusion: COVID-19 infection is now a frequent and a common cause of acute telogen effluvium. Hence, clinicians should be aware about the relation between this infection and this pattern of hair loss. Drugs that have been used for the treatment of COVID-19 were excluded as a cause of acute telogen effluvium.

The Proportion of Catagen and Telogen Hair Follicles in Occipital Scalp of Male Androgenetic Alopecia Patients: Challenging the Established Dogma.
Exp Dermatol
October 2024
Translational Research Institute, Academic Health System, Hamad Medical Corporation, Doha, Qatar.
Article Synopsis
- Hair follicles undergo a continuous cycle of growth (anagen), regression (catagen), and rest (telogen), with the time spent in each phase affecting hair length and health.
- Traditional beliefs suggest that 85%-90% of hair follicles are in the growth phase, but recent studies indicate that these values may not be accurate due to flaws in assessment methods.
- A new examination of hair follicles during hair transplants revealed that catagen follicles (7.5%) are more prevalent than previously thought, challenging the established belief about the distribution of hair follicles in different stages.
Asymptomatic SARS-COV2 Infection or COVID-19 vaccination effect for severe multisystem inflammatory syndrome in a 6-year-old girl: case report and review of the literature.

Article Synopsis
- Multisystem Inflammatory Syndrome in Children (MIS-C) can occur 3-6 weeks after a SARS-CoV2 infection, and vaccinated adolescents show fewer severe cases, but data on younger kids is limited.
- A 6-year-old girl developed MIS-C symptoms one month after receiving her COVID-19 vaccine, despite having no prior detectable infection; diagnosis was confirmed through antibody tests.
- Treatment with immunoglobulins and steroids helped her recover, but she experienced additional complications like pancreatitis and neurological symptoms; follow-up showed no lasting issues, raising questions about the vaccine's role in MIS-C for younger children.
Oral Vitamin D Treatment in Patients with Telogen Effluvium: Clinical and Dermoscopic Evaluation.
Int J Trichology
July 2024
Department of Dermatology and Venereology, Faculty of Medicine, Tanta University, Tanta, Egypt.
Article Synopsis
- Telogen effluvium (TE) is the most common type of hair loss, and Vitamin D may play a key role due to its effects on the immune system and inflammation.
- A study involving 40 women with TE showed significantly lower Vitamin D levels compared to healthy controls, but after 3 months of oral Vitamin D treatment, their levels improved considerably.
- The findings suggest that oral Vitamin D could be beneficial for TE, but more extensive research is needed to determine the appropriate dosages and treatment duration.

Article Synopsis
- Telogen effluvium (TE), a common hair loss condition related to COVID-19, was studied in patients with severe cases who were hospitalized.
- In a cohort of 77 patients, 68.8% experienced TE, with over half reporting early onset; 20.7% had complete hair regrowth within three months.
- Factors like being female, having anemia, and severe pneumonia were linked to TE, while the majority experienced good recovery, though 7.5% had chronic TE, highlighting potential long-term health impacts.
Article Synopsis

- Conducted at CHU Ibn Rochd in Morocco, the study involved 18 COVID-19 patients displaying various skin issues, including rashes and mucosal involvement, with 94.44% experiencing general symptoms.
- A significant portion of patients developed autoimmune diseases triggered by COVID-19, highlighting the need for greater awareness among clinicians regarding these skin-related complications.
