    TLDR Long-COVID symptoms can last more than a year and change over time.
    The study at the "Luigi Sacco" University Hospital in Milan followed 1168 COVID-19 patients, roughly half male and half female, with a median age of 57, for over a year to track long-COVID symptoms. The most common symptoms were fatigue (53.4%), dyspnea (36.6%), myalgia and arthralgia (36.5%), anosmia (22.3%), and ageusia (21.1%). Temporary hair loss, or telogen effluvium, was reported by 10% of patients. Most symptoms took over a year to resolve, with anosmia and ageusia taking 200 and 155 days respectively, and telogen effluvium taking 299 days. The study found that long-COVID symptoms can persist for over a year and do not resolve in a linear fashion but fluctuate over time.

      The conversation discusses whether lifestyle factors like diet and sleep affect hair growth in people with reversible hair loss. Some believe these factors, along with treatments like minoxidil, finasteride, and RU58841, can improve hair health, while others argue hair loss is mostly determined by genetics and DHT sensitivity.

      in Minoxidil  56 upvotes 1 year ago
      The post discusses the difference in effects of Minoxidil (Min) on scalp and facial hair. The user questions why Min-induced hair growth on the scalp is temporary, while facial hair growth seems permanent, even after stopping Min. They propose theories, including different Min mechanisms on body and facial hair, the role of DHT, and the possibility of not achieving fully terminal hair. The responses include personal experiences and theories about Min's effects on hair growth.
