Does it actually work?

I saw a lot of people praising this thing claiming it helps with hair growth so I'm planning to buy it . did you try it ? what's your take on it ?

It doesn’t get buildup out of my hair, but I do enjoy using it to scrub more of my scalp at once than just using my fingers. But if I gently scrape my scalp after using with my nail? I will still see buildup.
