I used one of these. Mainly human grease and wife's hair. Works well, but the stuff that comes out stinks! You can get 10 metre long ones.

I've got that one

I've just usually used the Mr Muscle Sink & Drain Gel in the orange bottle. I've tried cheaper copy's of it from Home Bargains etc, but it doesn't work if it's badly blocked. It hasn't done any damage yet that I know of and is very effective.

Bicobonate of soda,white vinegar.Leave it to soak for a while then rinse out with hot water.
You need these for the bath !

If I can't clear the blockage manually I use stuff called 'One Shot'.

You should be able to get it from a plumbers merchant.
Strong stuff, 91% Sulfuric acid, I've ruined several pairs of trousers by splashing them, then after washing they are full of holes.
It's also good for cleaning the limescale build up in WCs.
I probably get through about 10 litres a year.
