Reply From the Authors: Correction on β-Estradiol Concentration in Hair Growth Study

    July 1998 in “ Journal of Investigative Dermatology ”
    K Stenn, R Paus, M Filippi
    TLDR Correcting their experiment, the authors confirmed β-estradiol affects hair growth in mice.
    The authors acknowledged a mistake in their initial experiments regarding the concentration of β-estradiol used, which differed from the original report by Oh and Smart. Upon repeating the experiments with the correct protocol, they confirmed that β-estradiol inhibited the normal progression of spontaneous anagen in pigmented mice. This led to new insights into estrogen receptor-mediated signaling in murine hair growth control. They expressed gratitude to Drs. Oh and Smart for highlighting this phenomenon and planned to share further findings in a future report. An editorial error prevented Drs. Smart and Oh from responding to the original letter, for which an apology was issued.

      The conversation discusses the side effects of finasteride, including low libido and erectile dysfunction, and the possibility of these effects being permanent, known as post-finasteride syndrome (PFS). Some users report personal experiences with PFS and debate whether the condition is real, with varying opinions on the reversibility of side effects and the role of individual biology.
