HairGenics Pronexa Hair Loss Serum Review + Ingredients Explained

Pronexa is certainly not the best hair loss treatment I’ve ever seen but it two worthwhile ingredients. This product may mildly stimulate hair growth due to the pea sprout extract, which is thought to increase the growth factor FGF7.

Ingredients Explained

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.

Castor oil

Castor oil is a rich source of ricinoleic acid, which has been shown to increase PGE2 when applied to the scalp.


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.
