Derma roller without serum

[Efemu]

I just bought a derma roller and told my friends about it, one of them said it doesn't do anything if you're missing on a hair growth serum but he's not really trustworthy.
Can u guys help me, does it still work with out minoxidil...

the only you gotta keep in mind is disenfecting your roller every time you use it

f you're missing on a hair growth serum

Hair serum are copes, only reserached ingredients matters
