The majority of users are ecstatic. Here is the typical sentiment expressed across platforms:
"It dissolved a dead rat's worth of hair in 10 minutes." – Reviewer, Amazon AU.
"Better than a snake. The snake just pokes a hole; this removes the residue."
"Works on the plug hole hairball."
"Safe for PVC if used as directed."
The high viscosity is critical. Liquid unblockers drain past the hair plug instantly; HG gel pools on top of the standing water, maintaining chemical contact with the hair mass. Sodium hydroxide hydrolyzes the disulfide bonds in keratin (hair protein), turning it into a soluble amino acid sludge.
HG has earned its cult following. It is not a miracle for every drain problem, but for the specific, agonizing problem of a hair-clogged shower waste, it is arguably the best consumer-grade product on the market. The complaints are largely about packaging and user impatience. If you follow the instructions, wear gloves, and give it an hour, the HG Drain and Plug Hair Unblocker will likely save you a £150 plumber callout. hg drain and plug hair unblocker reviews

Before we get into the reviews, it is essential to understand that HG (brand origins from the Netherlands, now distributed globally) produces a specialized line of drain cleaners. Unlike generic "Drano" or "Mr. Muscle" which are broad-spectrum alkalis meant to dissolve everything from grease to food, HG focuses on keratin dissolution.
How does HG stack up against the alternatives? Let’s compare using real-world criteria.
| Product / Method | Effectiveness on Hair | Speed | Safety Risk | Cost per use | Pipe Friendly | | :--- | :--- | :--- | :--- | :--- | :--- | | HG Hair Unblocker | 9/10 (Melts completely) | 15 min | Medium (Burns/Fumes) | $$ | High (if used correctly) | | Drano Max Gel | 7/10 (Leaves residue) | 30 min | Medium | $$ | Medium (Hot reaction) | | Mr. Muscle (Black bottle) | 6/10 (Better for grease) | 20 min | Medium | $ | Medium | | Mechanical Snake (25ft) | 5/10 (Pushes through, but returns) | 45 min (labor) | Low (Hardware injury) | $$ (Tool cost) | High (No chemicals) | | Baking Soda & Vinegar | 1/10 (Wives tale; creates pressure, no melt) | 60 min | Low | $ | High (But useless) | | Plunger | 2/10 (Only for loose blockages) | 10 min | Low | $ | High |
Verdict: HG wins the hair category decisively. It is faster and more thorough than mechanical methods, but it requires caution.
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. "Better than a snake

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.
Here is my full, honest review.
