My sister gave me her stash of CP serum and super CP serum. I use 50% diluted Folligen every night. Is it ok if I mix in some CP serum or super CP serum into my daily folligen application? (Not to the bottle but mixed in my daily dropper).

Thanks

Dear jaha:

Sure - that's fine! We have clients that regularly use Super CP Serum on their hair as their "Folligen substitute".
