Getting Started
What is the WEETALL Red Light Therapy Hair Growth Cap?
The WEETALL Hair Growth Cap is a cordless wearable device designed for convenient at-home scalp care. It combines 660nm Red Light and 850nm Near-Infrared Light technology to support scalp wellness and healthier-looking hair as part of your regular hair care routine.
How does Red Light Therapy work?
Red Light Therapy uses specific wavelengths of light that are commonly used to support scalp health. Regular use may help create a healthier environment for healthier-looking hair. It is completely non-invasive and requires no medication or recovery time.
Who can use this product?
This product is intended for adult men and women looking to improve their daily hair care routine and support scalp wellness at home.
Using Your Hair Growth Cap
How often should I use the cap?
We recommend using the cap once daily for 10–20 minutes. The built-in automatic timer turns the device off after 20 minutes for convenient daily use.
How long does it take to see results?
Hair grows naturally in cycles, so visible improvements take time. Most users are encouraged to use the device consistently for at least 16 weeks before evaluating their progress. Individual results may vary.
Can I use the cap more than once a day?
We recommend following the suggested daily treatment time. Longer or more frequent sessions are not recommended unless advised by a healthcare professional.
Can I use it on wet hair?
No. For the best experience, make sure your hair and scalp are clean and completely dry before using the device.
Can I wear the cap while reading or working?
Yes. The lightweight cordless design allows you to use the cap while reading, relaxing, watching TV, or working from home.
Product Features
Why can't I see the 850nm Near-Infrared Light?
This is completely normal. The 660nm Red Light is visible, while the 850nm Near-Infrared Light is outside the visible spectrum and cannot be seen by the human eye.
What do the charging indicator lights mean?
- Slow flashing: Charging
- Fast flashing: Low battery

How long does the battery last?
The built-in 2000mAh rechargeable battery supports multiple treatment sessions on a full charge. Battery life varies depending on brightness settings and usage.

Can I use Minoxidil or hair serum with the cap?
In most cases, yes. However, your scalp should be clean and completely dry before each treatment session. Always follow the instructions provided with any topical products you use.
My scalp feels warm or slightly itchy. Is this normal?
Some users may experience mild warmth or slight itching when first using the device. If discomfort persists, discontinue use and contact our customer support team.
