Aminexil/Kopexil may help reduce hair loss by addressing perifollicular fibrosis in androgenetic alopecia, but it lacks the extensive clinical backing of finasteride and minoxidil. Some users find it effective, but availability and cost are issues, especially in the US where it's not FDA-approved.
Safflower oil is suggested as an alternative to minoxidil for hair growth, with benefits including scalp conditioning and hair strength enhancement. Studies indicate it may also reverse scalp dermatitis, alopecia, and prevent premature grayness.
PP405 shows promise in hair regrowth, with 31% of participants experiencing over 20% increase in hair density after 8 weeks. Phase 3 trials are expected in 2026, with potential market availability by 2029-2031.
Microneedling may enhance hair regrowth by transferring stem cells to dormant follicles, improving the effects of minoxidil. Users discuss using microneedling with needle lengths around 1.5mm to stimulate hair growth.
