It's difficult to point to one strategy or resources as best because children vary. However it is crucial that you are on the same page as parents in raising your child, so the child experiences consistency and does not learn to use a "divide and conquer" strategy to gain control over the adults.
That said, one strategy may include placing a locking doorknob on the master bedroom and/or closet doors to reinforce that you are serious about specific belongings such as make up being off-limits.
Wishing you all the best.
