Changes in hair measurements with LED light
The study reported changes in hair density and diameter with both LED colours.
Tantiyavarong et al. · 2024A non-invasive red-light session directed at the scalp. Discuss the device, its intended use and your suitability with Becky.

This is a non-invasive appointment that directs red light at the scalp. The clinic lists a 10-minute individual session. Light-based research is often described as photobiomodulation: using defined light settings to influence biological activity.
Light colour alone does not describe a treatment. Ask which device is used, its intended purpose, settings and proposed schedule before deciding.

Tantiyavarong et al. · 2024A particular mixed laser-and-LED helmet increased target-area hair counts more than sham.
Lanzafame et al. · 2014Human studies using specific light devices have reported improvements in hair measurements in people with pattern hair loss. The research below includes a mixed laser-and-LED helmet and an LED colour comparison. It offers useful context when discussing whether a light-based approach could fit your plan.
Benefits depend on the device, light settings and treatment schedule. The mixed-light trial cannot isolate an LED-only effect, and the LED colour comparison was small and did not describe a sham arm. Confirm the clinic equipment and proposed course; these studies do not establish the same result from a different device or a single session.

Small active-colour comparison; no sham arm described in the abstract. It does not validate another LED device.

It used both lasers and LEDs. The study cannot isolate an LED-only effect or prove this clinic device matches.

Talk to Becky about your next stepLight-based hair treatments vary by device, wavelength and treatment schedule. Ask which device is used, what evidence supports its intended use and what a full course would involve.
Tell the practitioner about light sensitivity, relevant medicines and your health history. Ask about eye protection and any preparation or aftercare instructions.
An individual LED session does not guarantee new growth or improved density. The underlying cause of your concern matters, and a medical assessment may be the appropriate starting point.
Open a question for the details. For advice about your own hair or scalp, speak with Becky.
No. Devices and treatment protocols differ, so claims about one device should not be assumed to apply to another.
Please arrange a consultation first so Becky can discuss whether it is an appropriate option for you.
