Hair growth remedies

So I make really irrational decisions with my hair as I always end up acting on impulse. Well last week I got the ugre to cut my hair short and I cannot be trusted when I get these urges lol. Well I couldn’t get in with my normal stylist so I went somewhere else which was a big mistake. Well I don’t hate the length the hair dresser just botched the layers and it’s horrible.

I know nothing is going to make my hair grow magically fast but I need remedies that help promote growth. Even if there’s something that really doesn’t work and just provides the placebo effect that’s fine lol. I just need to feel like my hair will be okay lol
