Will these tips and tricks actually help my hair grow?

I haven't had my hair cut in such a long time because I want longer hair, but it's left me with so many split ends and I'm told that slows down hair growth?

I'm willing to get my hair trimmed, or cut as much as necessary if getting your ends trimmed actually helps your hair grow quicker, does it?

I've also bought holland and barretts skin hair and nails tablets, do these work? And I've also bought their kelp tablets, do these work?

Any info would be amazing and if anyone knows of any tips of tricks that work for hair growth that would be great.

Thank you :)

Split ends have no impact on the rate of hair growth. Hair grows at the root, NOT the end.
