EGFR/MEK Inhibitor Therapy Induces Partial Hair Follicle Immune Privilege Collapse In Vivo and Ex Vivo

A 23-year-old male is experiencing diffuse hair loss and miniaturization, possibly due to high IGE levels after using tofacitinib. He seeks advice and has not yet consulted a dermatologist.

TDM-105795 showed promising hair growth results, with higher efficacy than placebo and minimal side effects. It activates dormant hair follicle stem cells and may maintain gains without immediate loss, unlike minoxidil.

PP405, a topical LDH inhibitor, has shown to stimulate hair follicle stem cell proliferation in humans with moderate hair loss. They are advancing to more detailed trials this year.

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.

Epibiotech will offer off-the-shelf allogeneic hair multiplication treatment in South Korea, using dermal papilla cells from donors to grow hair in balding areas. This method is cheaper and less invasive than traditional hair transplants.

PP405, a topical treatment, shows promise for hair growth by activating inactive follicles, with 66% of participants experiencing positive results. The treatment is well-tolerated and may proceed directly to Phase 3 trials, offering a potential alternative to minoxidil and finasteride.
