as follow or as follows
“as follows” is always singular whether the preceding matter is plural or not. It is used either as a phrase or as an idiom to mean what comes next, usually in the form of a list.
#The reasons for these decisions are as follows.
In case you don’t want to use it this way, you can say:
Here are my reasons, or My reasons are, first,…, and the like.
Never say “as follow”.
That is English for you.
