    TLDR Hair properties change under electromagnetic fields and are influenced by individual characteristics and the environment.
    The document reported on a study that used Electro Photonic Analysis (EPA) to examine the properties of hair and non-hair fibers and the effects of various hair treatments. It was found that non-hair fibers had significantly higher Area and Intensity of glow than hair samples, and that bleaching significantly altered hair properties, while other treatments did not. The study involved six swatches per sample type and utilized a GDV camera for measurements. Increased humidity was shown to reduce the glow area of hair samples. The experimental errors were within 5-8%, indicating reliable data. The study concluded that hair properties can be affected by an electromagnetic field and that these effects vary based on individual hair characteristics and environmental factors.

      This conversation was about a user named Substantial_Pen_1099 who has been using an regimen of 5mg oral minoxidil, 1mg finasteride everyday, 2% keto shampoo every three days, and weekly 0.5mm dermarolling for hair loss treatment over the course of 3 months. Others in the conversation expressed disbelief at their progress, to which Substantial_Pen_1099 provided video proof as evidence.

      DHT may inhibit hair growth by affecting mitochondrial function, leading to hair follicle miniaturization. Treatments like minoxidil and PP405 may promote hair growth by altering metabolic pathways, potentially counteracting DHT's effects.

      Rotenone, a natural plant extract, may promote hair growth by increasing LDH activity and blocking MPC in the scalp, but it carries risks due to its toxicity. The suggested formulation includes Barbasco extract, DMSO, propylene glycol or PEG-400, ethanol, and a carrier oil.

      community Verteporfin and Microneedling

      Clinical studies by Dr. Barghouthi and Dr. Bloxham indicate that Verteporfin, when used with FUE and FUT hair transplantation methods, shows promise in hair follicle regeneration and minimal scarring due to its ability to inhibit Yes-associated protein (YAP). Microneedling at depths of 3-3.5mm, combined with Verteporfin, could potentially reactivate dormant follicles, although the optimal dosage and application method are still under investigation. Concerns remain about the DHT sensitivity of regenerated follicles, highlighting the need for further research to optimize trauma levels and Verteporfin concentrations to achieve effective and scar-free hair regeneration.
