Pea sprout extract
Pea sprout extract has been shown in at least one study to increase scalp FGF7. FGF7 is a growth factor which was found to more highly expressed during the growth phase of the hair follicle and less so when the hair follicle stopped growing. By increasing scalp FGF7 the hope is that the growth phase of hair follicles will be lengthened.
Malus Domestica (Apple) cell culture extract
I believe this ingredient is referring to stem cells taken from apples. If so this ingredient is probably included for the ‘epigenetic factors’ found in a particular variety of Swiss apple. According to Mibelle Biochemistry, these stem cells delay senescence of hair follicles. That basically means they prevent deterioration of the cells with age.
Pronexa is an interesting and simple topical treatment for hair loss. It’s the first time I’ve come across apple stem cells as a treatment for hair loss. Pea sprout and castor oil are known to me and are useful ingredients to include. However, this is not a particularly powerful hair growth stimulating treatment and I wouldn’t expect significant results.
