Red Light Therapy Cap

The cap uses 650nm red light — the clinically studied wavelength shown to penetrate the scalp at the correct depth to stimulate hair follicle activity. Research published in peer-reviewed journals including Lasers in Surgery and Medicine has demonstrated that 650nm low-level laser therapy significantly increases hair count and density in both men and women with androgenetic alopecia. Wavelengths outside this range are less effective at reaching the follicle.

Clinical protocols use 25-minute sessions, 3 to 5 times per week. The built-in auto-shutoff timer handles the session length automatically. Consistency is essential. Most users see reduced shedding within 4 to 6 weeks and new growth becoming visible between 8 and 16 weeks of regular use.

Red light therapy at 650nm is most effective for androgenetic alopecia (pattern hair loss) and telogen effluvium (stress or hormonal shedding including postpartum loss). It is less effective for alopecia areata (autoimmune hair loss) and is not suitable as a standalone treatment for chemotherapy-related hair loss. Consult a dermatologist if you are unsure of your hair loss type.

Yes. 650nm red light is non-ionising, does not emit UV radiation, and operates at a low power density safe for regular scalp use. It does not damage skin or hair follicles. Avoid looking directly into the LEDs during use. People with photosensitivity disorders or those taking photosensitising medications should consult their doctor before use.
