How Does It Work?
How Does It Work?
TheraBrush uses a powerful combination of science-backed technologies to create the ideal environment for hair growth and scalp health:
650nm Red Light Therapy: Penetrates the scalp to stimulate hair follicles, improve blood flow, and boost cellular energy (ATP), which supports thicker, faster hair growth.
450nm Blue Light Therapy: Helps reduce inflammation and bacteria on the scalp, promoting a cleaner, healthier environment for new hair to grow.
Essential Oil Diffusion: Gently infuses your scalp with any water based essential oil solution. Experience growth-supporting oils like Rosemary, Pumpkin Seed, Tea Tree, Lavender in our natural hair tonic.
Massage Vibration Therapy: Enhances circulation and reduces tension, delivering nutrients to the roots while helping relax the scalp.
These four therapies work together in a 10-minute daily routine to improve hair density, reduce shedding, and support long-term growth—naturally and pain-free.

Troubleshooting
Leaking
Leaking
Is your brush leaking? Rest assured we will help with a solution or send a replacement.
It is important to note that the brush is not waterproof, so if it is ran underneath the sink or in the shower, it could cause leaking.
Please check the slide cap on the top of the brush and ensure that it secured tightly.
If the cap is secured and it's leaking out of the head of the brush, or the charging port. There may be some internal damage, and we can send you a replacement!

Diffuser Mist Mode
Diffuser Mist Mode
Did you put pure oil in the chamber? Or did you put a water based solution?
The oil alone is too thick to turn into a mist and can actually clog the brush.
That is why the TheraHair tonic is a light, water based solution compatible with the brush!
If this is the case, you simply need to use hot water and rinse out the chamber thoroughly to unclog the diffuser. Repeat a few times to ensure all the oil is cleaned out.
Once cleaned, add your water based solution and try again!
