There aren’t really many side effects to speak of. There’s definitely nothing serious.
I’ll keep this page updated in case I find any but there certainly isn’t anything major.
You could experience things like temporary shedding (getting rid of the unhealthy hair), a change in appetite, digestive issues, metabolic issues and urinary issues but all are minor and are usually only temporary. You could also try reducing your dosage until you find the right levels which will allow you to grow your hair without any side effects.
