RegrowRx Hair Regrowth Spray
About this medicine
RegrowRx Hair Regrowth Spray is a compounded prescription preparation used to help prevent hair loss and promote hair growth. This compound consists of:
- Minoxidil (5%), a medication which stimulates the microcirculation around the hair follicles to induce arteriolar vasodilation, thereby encouraging conditions conducive to hair growth.[1] It also causes a prolongation of the anagen hair phase and helps increase hair follicle size.[2]
- Melatonin (0.1%), a hormone which the body produces but can also come from other sources. It has many properties which can help reduce hair loss. First, it is a potent antioxidant that helps protect the hair follicles from oxidative stress. Second, it has anti-inflammatory properties which can help keep the scalp healthy and more conducive for hair follicles to grow. Next, melatonin has been shown to inhibit the conversion of testosterone to dihydrotestosterone (DHT). DHT is implicated in androgenetic alopecia. Lastly, it helps widen blood vessels, improving blood flow to the hair follicles.[3]
- Tretinoin (0.01%), a derivative of vitamin A which has properties conducive to the promotion of hair growth. It has been shown to promote cell proliferation and differentiation in the skin, which means it helps maintain the health and function of the hair follicles. Tretinoin has also been shown to improve blood flow, therefore delivering oxygen and nutrients to the skin where applied to promote healthier hair growth.[4]
- Caffeine (0.2%), a drug that has been shown to promote cell proliferation and cell metabolism enhancing the function and vitality of hair follicle health. It has also been shown to inhibit DHT, which as mentioned above is implicated in hair loss. Caffeine has also been found to enhance hair shaft elongation and stimulate hair matrix proliferation.[5]
