Hair growth stimulation, does anything actually work?

Hello ladies! So I used to have long healthy hair (mid-waist length), but before I went abroad as part as my degree, I chopped it off and went for a bob (new year, new me). HOWEVER, my hair was cut in different lengths and it was really embarrassing to go out in public, and it still is. Fast forward two years (now) and it still hasn't grown enough for me to cut it all to one length without going shorter. I also suffered alopecia this year due to final year exams, anxiety, corona etc. Plantur tonic is great for this by the way! Anyway, I need something else that helps grow my hair quickly and healthily, bar coconut oil. I've seen pills like perfectil, hairtamin but i'm reluctant to try them. Does anyone have any experience in this and would recommend any oils/tablets/regimes? Thanks all and stay safe!
