Cordyceps hair shedding and itchy scalp

[Marshmello]

I recently started using cordyceps powder for well being and motivation which it worked really good for.
But I noticed that my scalp gets really itchy and red and my hair starts shedding.

I have not seen anyone else with this problem while searching on the internet so I wonder what could be the cause of this? If anyone could
