Frequently Asked Questions
Powered by premium laser diodes, the cap delivers low-level red light therapy at a clinically proven 650nm wavelength. This targeted treatment is designed to:
- Stimulate the Scalp: Boosts blood flow and cellular metabolism directly at the follicle.
- Prolong Hair Growth: Extends the anagen (growth) phase of your natural hair cycle.
- Enhance Density: Strengthens individual follicles to promote visibly thicker, fuller, and healthier hair.
This device is clinically cleared to treat androgenetic alopecia—commonly known as genetic male or female pattern hair loss.
To ensure the best possible results, please note that this treatment relies on active hair follicles and is not intended for:
- Temporary or situational hair loss (such as postpartum, stress-related, or chemotherapy-induced)
- Underlying medical conditions (including autoimmune hair loss or scarring alopecia)
- Advanced hair loss (complete baldness)
The cap features an interior circumference of 22.5 inches, which is specifically designed to provide a comfortable fit for most head sizes.
To ensure the perfect fit for you, we highly recommend taking a quick measurement of your head's circumference before placing your order.
Consistency is the key to maintaining your new growth. Because the low-level laser therapy actively stimulates your follicles, stopping the treatments will cause your hair's growth cycle to slow down and gradually return to its original baseline state.
The treatment is completely painless and feels just like wearing a standard cap. During your session, you may experience a gentle warming sensation on your scalp—this is perfectly normal and simply a sign that the light therapy is actively working.
Currently, the cap is FDA-cleared specifically for use on Fitzpatrick Skin Types I-IV, which range from fair to medium skin tones. Please note that for safety and compliance, it is not cleared for use on Types V-VI, which include darker complexions.
