    TLDR Adenosine helps hair grow longer and stronger by boosting certain growth factors and signaling pathways.
    This study investigated the effects of adenosine on hair follicles and dermal papilla (DP) cells, revealing that adenosine stimulated DP cell proliferation and extended the anagen phase of hair growth by increasing cysteine uptake in mouse vibrissae hair follicles. Adenosine also promoted the expression of growth factors such as FGF-2, FGF-7, IGF-1, and VEGF, and increased β-catenin transcriptional activation, which is crucial for hair follicle morphogenesis and differentiation. Additionally, adenosine activated downstream signaling pathways, including ERK, CREB, and AKT, suggesting its potential as a therapeutic agent for hair growth by enhancing growth factor expression and signaling pathways.

      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.

      Comparing the effectiveness of minoxidil 5% and adenosine 0.75% for treating male androgenetic alopecia, and measuring patient satisfaction rate; results showed that adenosine is comparable to minoxidil but provides quicker results, however availability of products with adenosine is much less than those with minoxidil.

      30 y/o male started balding at 22, began treatment at 29 using oral dut, oral min, derma rolling, nizoral shampoo, and considering low level light therapy. Plans to monitor progress for 1-2 years and may get hair transplant or use hair system if needed.
