Devices for hair growth

Devices for hair growth include red light hats and helmets, laser caps, LED combs, microneedling tools and scalp massagers. They are not NHS treatments. In the red light hat category, our top pick is the RedLight Innovation Hat Pro at £372.

See a GP if hair loss is sudden, patchy, or comes with illness, a rash, or other symptoms. The NHS asks for that conversation before a private clinic.

A device is something you put on the scalp. It is not a diagnosis, and it is not a prescription. The useful question is which job it claims to do.

Where does red light sit?

Research suggests red light may help with pattern hair loss when people use it consistently over months. That sentence is as far as the trials go. The evidence page has the numbers. The buying guide is how to choose a hat.

Our top pick in that category is the RedLight Innovation Hat Pro at £372: three red wavelengths, about 80% coverage, and a washable cap. Read the comparison or the Hat Pro review.

What should you skip?

Skip any device page that promises a cure, hides the session time, or will not say what the light is. Skip a massager sold as if it were a laser. And skip the purchase entirely if the loss is sudden or patchy until a GP has seen it. The NHS is explicit about that order.
