    TLDR Vitamin A during pregnancy can harm fetal skin development.
    The study investigated the effects of retinoic acid (RA) on fetal skin when administered to pregnant albino mice. Twelve pregnant mice were divided into two groups, with the experimental group receiving 60 mg/kg/day of RA orally on days 7, 8, and 9 of gestation. Histological examination of the fetal skin from the RA-treated group revealed increased keratinocyte proliferation, resulting in more epidermal cell layers and greater epidermal thickness. Additionally, RA inhibited hair follicle development, which appeared as rudimentary buds in the dermis. The findings suggested that RA usage during pregnancy should be approached with caution due to its significant impact on fetal skin development.

      Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.

      community DLQ01: A Better "Minoxidil" PGF2a synthetic analogue.

      in Research/Science  3 upvotes 2 months ago
      DLQ01, a prostaglandin F2α analog, shows promise for hair growth by directly stimulating PGE2/PGF receptors without needing conversion, and can be combined with minoxidil and retinoids like tretinoin for enhanced effectiveness. Minoxidil's efficacy may be reduced by COX-1 inhibitors, but using prostaglandin analogs like Latanoprost or Bimatoprost can help maintain its effectiveness.

      community Painkillers May Block Minoxidil

      in Research/Science  13 upvotes 1 month ago
      Painkillers like Aspirin may reduce Minoxidil's effectiveness by inhibiting the enzyme PGHS-1, which is crucial for hair growth. Using NSAIDs that inhibit COX-2 or combining Minoxidil with PGF2/E2 analogues or retinoids may enhance its efficacy.
