This review discusses evidence-based complementary strategies for enhancing hair regrowth after post-COVID-19 telogen effluvium and reports no new clinical results.

This study suggests that women with polycystic ovary syndrome may have an increased risk of COVID-19-related cardiac and renal complications, and that weight loss through lifestyle changes could help reduce these risks.

This review discusses the repurposing of natural products for COVID-19 treatment but reports no new clinical findings, highlighting ongoing research to target host and viral mechanisms.

People with androgenetic alopecia had milder COVID-19 symptoms during the Omicron wave in China.

This study is investigating the efficacy and safety of proxalutamide, an androgen receptor antagonist, in treating severe or critically ill patients with COVID-19, aiming to provide new insights into potential therapeutic options. Results are not reported yet.

This review explores the role of androgens in both SARS-CoV-2 infection severity and the development of alopecia, concluding that androgens influence hair growth cycles and promote alopecia.

This study reports that comorbidities and anti-androgen therapy were associated with lower SARS-CoV-2 vaccination rates among patients with androgenetic alopecia, emphasizing the need to promote vaccination within this group.

In this study, rapamycin was found to increase hair follicle pigmentation and prolong anagen duration in cultured human scalp hair follicles, suggesting it could be explored as an anti-greying agent.

This study found that TPA treatment induced expression of keratins K6 and K16 in mouse epidermis, with K6 expressed across all cell layers and K16 only in post-mitotic cells.

This study introduces a new type of tissue micromodule, the micro tissue precursor (μTP), which can form complex 3D tissues, including lung stroma and skin models supporting hair viability.

This study suggests that a position effect disrupting TRPS1 expression may be linked to hypertrichosis in both Ambras syndrome in humans and a similar phenotype in Koa mice.

This study suggests that mouse keratin 6 isoforms, K6a and K6b, have overlapping but distinct expression profiles, differing notably in their expression in suprabasal cells and response to phorbol esters.

Krt6a-Cre transgenic mice help study gene effects on hair follicle development and tumor suppression.

This study found that in mutant NRAS melanoma, MEK inhibitors led to increased AKT signaling and reduced MIG6, a change that may enhance cell migration and invasiveness.

This study found that a single injection of Platelet Rich Stroma improved knee function and reduced pain and stiffness in patients with knee osteoarthritis over twelve months.

This review examines alopecia, its causes, the impact of micronutrients, and the role of the Mediterranean diet, noting conflicting data and a need for more research on diet's effect on hair loss.

This study found that iron retention in macrophages impairs hair follicle growth and delays wound healing in mice, highlighting the importance of macrophage iron release for skin health.

This review highlights that malnutrition, including deficiencies in proteins and micronutrients, may exacerbate allergic conditions like dermatitis and asthma by promoting inflammation, while adequate micronutrient intake supports regulatory immune responses.

This study found that iron therapy improved nonhematological symptoms and cognitive function in women with iron deficiency anemia, highlighting the need for attention to these symptoms in improving quality of life.

This research reviewed literature to evaluate the role of micronutrients in hair loss and hair growth, examining normal nutrient levels, their role in the hair follicle cycle, and their use in treatments, with data drawn from 92 peer-reviewed articles and reputable health organizations.

This study reported two cases of ryzophagia among nonpregnant women in the US, with symptoms resolving after iron dextran therapy, suggesting a link with iron deficiency.

This review discusses the varied levels of evidence linking nutritional supplements and antioxidants to dermatological disorders, but it reports no new clinical results and highlights the need for rigorous trials.

This study in mice found that maternal iron deficiency led to hair loss and growth abnormalities in offspring due to increased oxidative stress and disrupted signaling pathways, but postnatal iron supplementation was able to reverse these effects.

This review highlights the critical role of iron in skin functions and suggests potential dermatologic therapies targeting the iron-skin axis.

This study found that using a pharmacogenetic panel with 26 SNPs can improve treatment outcomes for androgenetic alopecia, as overall response rates to minoxidil, finasteride, and dutasteride were high, and specific genetic markers predicted poor responses to these drugs.

This study at a medical center in Eastern Taiwan found that female alopecia has diverse causes, including nutrient deficiencies, autoimmune diseases, psychological stress, thyroid conditions, and COVID-19 vaccination, with iron deficiency affecting 70.3% of cases.

This study found that combining iron supplements with physiotherapy resulted in improved hair growth and condition in women with telogen alopecia and mild iron deficiency anemia.

This study found that combining iron supplements with physiotherapy improved hair condition and growth in women with iron deficiency-related telogen hair loss compared to iron supplements alone.

This study found that 6-methylsulfinylhexyl isothiocyanate (6-MSITC) significantly promoted proliferation and upregulated specific mRNA levels in human dermal papilla cells, suggesting potential as a hair growth stimulant.
