I recently bought this Red Light Growth Cap and used it for 3 weeks but it gave me headaches, so I have to stop. I assume my system is too sensitive for this product.
It has several light colors/frequencies. Each one gives you a different benefit. Most use it for hair growth, regrowth, and scalp health.
Retails for $200, but selling it for $100 since it's practically new.
No Holds
Cash only.
