Did you mean Laser Cap?

Glossary Laser Cap

A laser cap is a wearable device that utilizes low-level laser therapy (LLLT) to stimulate hair follicles and promote hair growth. It is relevant to hair loss treatment as it offers a non-invasive option for individuals experiencing androgenetic alopecia or other forms of hair thinning. Key distinguishing characteristics include its hands-free design, portability, and the use of specific wavelengths of light that are believed to enhance cellular activity and improve blood circulation in the scalp.
