Surely, the supplement company should have the best answer, yet I would attempt an explanation.
Hyperdrol X2 contains 6-Bromodione and an X2 Support Matrix (35% Osthol (Cnidium), Fulvic Acid, Proprietary Forskohlii Diterpene Extract, Cissus Quadrangularis Proprietary Ketosteroid Extract). I think the two compounds that may have hair-follicle-integrity-protection properties are cnidium and fulvic acid. Cnidium enhances cellular blood flow. This way, it helps to transport nutrients to hair follicles. This strengthens them and helps to prevent hair loss. This action is further supported by fulvic acid. As far as I recall, fulvic acid is the main active in shilajit, a mineral-type substance that is listed as a healing agent in ancient Sanskrit writings and is used today in Ayurvedic health practices as an adaptogen and general healing tonic. Fulvic acid is said to promote hair growth.
The X2 Support Matrix is a proprietary blend of 260mg. It is debatable if the constituent compounds are available in enough amounts in the blend to produce the desired impact.
