GlossaryPermanent Hair Dye

chemically alters hair pigment for long-lasting color

Permanent Hair Dye, also known as Permanent Hair Color, is a type of hair coloring product that chemically alters the natural pigment of the hair. It typically contains ammonia and peroxide, which open the hair cuticle and allow the color to penetrate deeply into the hair shaft, resulting in long-lasting color that can cover gray hair effectively. This type of dye does not wash out and generally requires new growth to be touched up.

community We already know how to permanently fix hair loss. The science is done. The only thing missing is the funding to run one experiment.

in Technology 613 upvotes 3 months ago

A permanent hair loss solution could involve reprogramming hair follicles to resist DHT using mRNA and siRNA. However, high costs, safety concerns, and the pharmaceutical industry's preference for ongoing treatments over one-time cures are major obstacles, with finasteride and minoxidil remaining standard treatments.

community Are permanent hair gains even possible?

in Chat 13 upvotes 1 year ago

Hair regrowth from treatments like minoxidil, RU58841, and finasteride is not permanent; stopping these treatments typically results in hair loss resuming. Beard hair can become permanent with minoxidil use, unlike scalp hair, which requires ongoing treatment to maintain gains.

community How come beard hair on minoxidil is permanent while scalp hair while on it under fin/duta is not?

in Minoxidil 50 upvotes 1 year ago

Beard hair grown with minoxidil can become permanent because it is not sensitive to DHT, unlike scalp hair, which requires ongoing minoxidil use even with DHT blockers like finasteride or dutasteride. Dutasteride reduces scalp DHT significantly but not completely, which may explain why scalp hair still needs minoxidil for maintenance.
