The Science
Light that speaks to your roots
The Hairo Advanced LLLT Hair Regrowth Cap is FDA-cleared Technology to deliver therapeutic red LED light (650nm,) to the scalp to stimulate hair growth and promote thicker, healthier-looking hair.
Red light therapy activates dormant hair follicles and works in the following ways:
- Boosts Cell Energy: Energizes mitochondria, leading to enhanced cellular energy and metabolism.
- Enhances Blood Flow: Ensures more blood reaches the scalp, combating root causes of hair thinning.
- Minimizes Inflammation: Fosters a healthier scalp and neutralizes threats like DHT, a byproduct of testosterone.Better-for-you, drug-free, non-invasive hair regrowth in the comfort of your home without the harmful side effects from drugs.
Each of the thousands of hair follicles on your scalp undergo a hair cycle:
- Anagen: Growth phase, lasts 2-8 years. Strong, healthy hair grows from the root.
- Catagen: Transitional phase, lasts 4-6 weeks. Hair growth stops, detaches from the blood supply, and the follicle shrinks.
- Telogen: Resting phase, lasts 2-3 months before restarting Anagen. Here the old hair strand falls out and the follicle lies dormant before entering Growth phase again.
Red light therapy helps stimulate your follicles and move more of your hairs into the Anagen phase to grow back thicker and healthier.
