    TLDR Scientists discovered that certain stem cells from mice and humans can be used to grow new hair follicles and skin glands when treated with a special mixture.
    In 2016, researchers found that a combination of cultured Epidermal Stem Cells (Epi-SCs) and Skin-Derived Precursors (SKPs) from mice and adult humans could regenerate hair follicles and functional Sebaceous Glands (SGs). The Epi-SCs, when treated with a specific induction cocktail, differentiated into sebocytes and formed SGs. When implanted with SKPs, they formed SGs in association with hair follicles. The presence of the induction cocktail in the graft significantly increased the number of SGs formed. The newly formed SGs were functional, secreting lipids similar to normal skin and protecting against water evaporation. The study suggested potential applications in treating hair loss conditions and the development of bioengineered skin substitutes capable of regenerating epidermal appendages.

      The treatment for androgenetic alopecia involves using finasteride and minoxidil with intense exercise and cold exposure to boost metabolism and reduce androgenic effects, potentially leading to hair regrowth. This approach may activate biological pathways for improved hair and overall health.

      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.

      Procapil is marketed as a natural hair loss treatment but lacks strong evidence and is industry-biased. Minoxidil and Finasteride are the only FDA-approved treatments for androgenetic alopecia.

      A gel of keratin microspheres promotes hair follicle growth, showing similar effectiveness to minoxidil in mice. The treatment activates hair growth pathways and reduces inflammation, with potential applications in drug delivery for hair-related disorders.

      Treatments for hair loss, including finasteride, dutasteride, minoxidil, ketoconazole, microneedling, and low level laser light therapy, which aim to reduce DHT production, increase cell absorption and blood flow, and stimulate epidermal stem cells. It also stresses the importance of patience when using these treatments.
