The product was full of shortcomings without any good points... I think I bought it in bulk through home shopping, but I've just left it unused after using a few.

The hair pack is inside the hair cap, so it doesn't spread evenly on the hair. You have to rub and massage it while using it, but even then, it doesn't spread evenly and just ends up coating the scalp heavily. So I have to scoop out the pack from inside the cap with my hands and apply it to the hair, but it's inconvenient to wear the hair cap, and the sticker just peels off, making it a hassle in various ways. Moreover, the pack doesn't rinse out well.....And even though it's not that effective, my hair ends up stiff, yet limp and matted. I've seen many people using this product in the bathhouse, but I've never seen anyone using it comfortably on their own ㅋㅋㅋㅋㅋㅋ You have to help them use it ㅋㅋㅋㅋㅋ In conclusion, it's the worst.. Just use a different hair pack and a regular hair cap. That saves time and is much more effective.

If you want to apply it evenly, scoop out the pack from inside the hair cap with your hands and apply it to your hair before putting on the cap.

My hair became soft. It remained soft even the next day, and my hair was easy to brush. It was a bit better than just using a light treatment.

It was difficult to wear. In the end, I couldn't use it properly, so my hair stuck out a bit. Some reviews said there was a warming sensation, but I didn't feel it at all. It was just cold, cold. The next day, my hair became extremely voluminous. Some people might like it, but for me, it looked too messy and my hair looked bigger and strange.

It seems like it would work well if you just wear it properly.
