Let’s be honest: unblocking a shower drain is one of the least glamorous jobs in home maintenance. But when you’re standing in two inches of soapy water because the water refuses to go down, you stop caring about glamour and start caring about results.
I’ve tested powders, gels, plungers, and those plastic zip-strip things (which work, but are disgusting). Recently, the HG Drain and Plug Hair Unblocker kept appearing in “best drain unblocker” lists. So I bought a 500ml bottle (around £8–£10) and put it to the test on a genuinely neglected bathroom sink and shower drain.

It comes in a simple, no-frills bottle with a child-resistant cap and a safety nozzle. The key selling point? It claims to clear a blocked drain in 5 minutes without needing to plunge or dismantle pipes.
I scanned Amazon, Screwfix, and Reddit to see if my experience was typical. Here’s what others say:
“I’ve tried Drano, Mr Muscle, and caustic soda crystals. HG is the only one that cleared my wife’s long hair from the shower in one go.” – Amazon reviewer, 5 stars
“Works brilliantly but follow the safety instructions. I got a tiny splash on my arm and it stung for an hour. Gloves are not optional.” – Screwfix comment, 4 stars HG Drain and Plug Hair Unblocker Reviews: Is

“My drain was 90% blocked. After 30 minutes with HG, it’s like a new pipe. Unbelievable.” – Toolstation review, 5 stars
Overall online rating: 4.5 / 5 stars across ~2,500+ reviews.
Pro tip: Use monthly maintenance – 100ml for 5 minutes – to prevent future clogs. The Pros (What I Loved) What Exactly Is HG Hair Unblocker
The "ugly" part of the reviews isn't the product failing; it's the user failing safety.
To get the best results, skip the instructions on the back of the bottle (which can be vague) and follow the method recommended by heavy users:
For a completely blocked pipe (zero drainage), you may need to leave it for 60 minutes or repeat the treatment. It’s not magic for a solid plug of hair.
