Dr uses Latisse on scalp. Here is the youtube link
I’d consider this as human experimentation and there is no evidence that Latisse (bimatoprost) grows hair on the scalp. It was FDA approved for growing longer eyelashes, but it is not approved for use on the scalp. Could it work? Possibly, but I don’t know why you’d want to be the guinea pig. Aside from potential safety risks in applying it all over the scalp, there is the financial part of it since the drug is normally sold in a very tiny tube meant to apply to eyelashes.
I’ve embedded the video here:
