Reader question:
Are these ingredients safe and do they interfere with any hormone production? I’ve had a look on Google about the ingredients, and for example valporic acid was shown to decrease LH and FSH. Have you noticed any side effects like this?
My answer:
All of the side effects from VPA use you’ll see online relate to using it orally. This is because when it’s used orally the patients are consuming thousands, or even tens of thousands greater volumes than you would use when applying the serum to your scalp. This is because there is less VPA in an entire bottle of Growth Factors serum than there is in one oral VPA pill. Plus, when you apply the serum topically only a tiny amount absorbs into the bloodstream. Therefore any side effects will be minimal. I do however advise using it sparingly and if you do experience any side effects, discontinue use for 48 hours.
