Tried the grom md shapoo and follicle activator for a couple of years. It was in addition to Fin & Regaine- certainly didn't hurt in maintaining.
I am in the UK, and you used to be able to order it from the US without an issue. Last year, they had a 50% discount on both offerings, so you could get both products for a combined 50$ per month.
Looks like they have icnreased the prices since then and also no longer allowign exports to the UK.
So if you are a UK customer, you have to source it from the UK site for....£60 for each product. So its a no-go from me, and I dounbt I'll be taking reviews too seriously goign forward.
