Hair loss: medical before cosmetic

The hair-loss industry is built on selling treatment before diagnosis. Serums, supplements and devices are marketed to people whose thinning has never been examined by anyone qualified to explain it. The order is backwards.

Thinning hair is a symptom with a differential diagnosis: pattern loss, thyroid, iron, post-partum shedding, autoimmune conditions, medication effects. Each has a different correct response, and several need a GP rather than a clinic.

The cause decides the treatment. Anything else is guesswork.

At Lumière every hair journey begins with a doctor-led assessment — history, examination and blood tests where indicated. Treatment follows diagnosis, and sometimes the honest conversation is about what medicine cannot give back.

Men, in particular, often arrive having spent years and significant money on products that could never have worked for their pattern of loss. One consultation usually explains why.
