Author Response: Intercellular Propagation of Extracellular Signal-Regulated Kinase Activation Revealed by In Vivo Imaging of Mouse Skin

Fatty acid metabolic signaling can activate epithelial stem cells for hair regeneration. Oleic and palmitoleic acids showed the best results, but practical application on humans remains uncertain.

Applying Epidermal Growth Factor (EGF) topically may improve skin and potentially promote scalp health and hair growth, especially after microneedling. The user shares their positive experience with EGF and provides a product link.

The conversation discusses using PGE2 as a hair growth stimulant, comparing it to minoxidil, and considering the addition of Setipiprant. Concerns about side effects like skin damage and cost are also mentioned.

Hair loss may be linked to the TRPS1 gene and protein, not just DHT. Amplifica's AMP-303 targets mesenchymal stem cells and shows promise in treating hair loss, unlike Pelage's PP405.

Emerging hair loss treatments like PP405, a topical MPC inhibitor, show promise in activating stem cells for hair growth. The conversation seeks information on the development stages and accessibility of these treatments.

Adipose-derived stem cells with ATP improved hair regrowth in male and female mice with androgenetic alopecia. The most effective treatments were low dose stem cells with ATP for males and medium dose stem cells with non-liposomal ATP for females.
