By condition
Hair loss is not one disease, and the treatments are not interchangeable. Each page lists what is approved and what is in development for one specific condition.
- Androgenetic alopeciamale pattern baldness · common baldness · AGAThe common, gradual, hormone-driven thinning that accounts for most hair loss in men and a large share in women. It is the indication almost every programme in this register is aimed at.
- Alopecia areatapatchy hair loss · autoimmune hair loss · alopecia totalis · alopecia universalisAn autoimmune condition in which the immune system attacks the hair follicle, causing patchy or total loss. It is not pattern baldness and does not respond to the same treatments.
- Female pattern hair lossfemale pattern baldness · hair thinning in women · FPHLDiffuse thinning across the crown rather than a receding hairline, and the form of hair loss most under-served by the pipeline relative to how common it is.
- Telogen effluviumsudden hair shedding · postpartum hair loss · stress hair loss · hair loss after illnessA sudden, diffuse shed that follows an illness, a birth, surgery, a crash diet or severe stress, typically two to three months after the event itself.
- Scarring alopeciacicatricial alopecia · frontal fibrosing alopecia · lichen planopilaris · CCCAA group of conditions in which inflammation destroys the follicle and replaces it with scar tissue. Unlike the others here, the loss is permanent once it has happened, which makes stopping the inflammation early the whole game.
- Chemotherapy-induced alopeciahair loss from chemotherapy · chemo hair loss · permanent chemotherapy-induced alopeciaHair lost during cytotoxic treatment, and — separately and less well known — hair that does not come back afterwards.
