Support women's hair thinning with red light
What research says about red light and female pattern thinning.
What research shows
One of the best-known sham-controlled trials of a 655nm light helmet was carried out in women, with meaningfully higher hair counts in the active group.
Why it works
Women's thinning usually spreads across the top and along the part rather than at the hairline, which is exactly the area a cap covers.
Relevant wavelengths
650–660nm red supports the follicle environment; 850nm near-infrared reaches deeper. Part long hair through the cap so light reaches the scalp.

FAQ
Yes. Women's thinning usually shows as a wider part or less volume on top, which a cap covers well. Used consistently, most women look for fuller-looking hair after about 4–6 months. Results vary.
Shedding after childbirth is common and often settles within months, so speak to your doctor first, and do not use a cap during pregnancy. Gradual thinning around menopause is a common reason women start a long-term red light routine.
