As someone who's always found zinc pyrithione to be a great match for my scalp, I've been a loyal user of Head & Shoulders products. However, I noticed that most Korean anti-dandruff shampoos are now switching to piroctone olamine. For me, not using zinc pyrithione is a surefire way to trigger seborrheic dermatitis - it's like my scalp has a sixth sense! Anyway, that's how I stumbled upon this shampoo after some desperate searching. To be honest, I didn't have high expectations due to its low price, but I'm pleasantly surprised that it hasn't caused any itching or side effects, so I've been using it consistently.
The shampoo has a white, viscous texture and lathers up nicely. The scent is a bit peculiar, with a hint of menthol perhaps? It's not amazing, but it's not bothersome either. Thanks to the menthol, it gives a refreshing, cooling sensation. I've found it works even better if you leave the lather on for 2-3 minutes while brushing your teeth before rinsing.
One downside is that if you don't rinse thoroughly, it can leave a residue (though this is common with most zinc pyrithione shampoos). Also, I haven't really noticed any significant effects on hair loss prevention. Still, I'm satisfied just knowing it keeps my seborrheic dermatitis at bay.
