I like the Topline stretchy bands,too. I also use the small scrunchies bands as they seem to be easy on the hair. Regardless of which band I use, at night I loosen it and message her scalp- she loves the message part!
Vellus makes two products that supposedly help with hair growth. I use them both but not for hair growth so can't really speak to that, but some of the folks that show speak highly of it for that reason. Maybe some of the other shiw folks here will weigh in on that.
Vellus Satin Cream
Vellus static Stabilizer
Good luck!
