learn Clascoterone

Can I use clascoterone if I'm undergoing gender-affirming hormone therapy? No published clinical trial has tested clascoterone in people on gender-affirming hormone therapy, so its safety in that group is unknown. The FDA label reports low systemic exposure and no described effect on blood testosterone, but it also records HPA-axis suppression and raised potassium in a small minority of subjects.

learn Low Level Laser Therapy

Red-light devices, such as caps, combs and helmets, used on the scalp

How does low level laser therapy actually stimulate hair growth? Low-level laser therapy is thought to work by boosting energy production in follicle cells. Sham-controlled trials report modest gains in hair counts, but the mechanism is not proven in people.
Can low level laser therapy be combined with topical treatments like minoxidil? Some small trials suggest adding laser therapy to minoxidil may help modestly, but the evidence is limited and mixed; a 2025 meta-analysis found no clear added benefit.
Who benefits most from low level laser therapy—men, women, or both? Sham-controlled trials report hair-count gains in both men and women. The largest trial reported that the gain did not depend on sex, but no trial was designed to compare men with women.

learn Vitamin B1

Can low vitamin B1 or B2 cause thinning hair? There is no verified human trial showing that B1 or B2 deficiency causes thinning hair or that correcting it regrows hair; a 2019 review concludes the role of micronutrients in hair loss is real but unclear and still needs controlled trials.
