Hi, Judy. I'm Japanese. I'm sorry but you're not using the Fino hair mask how you're supposed to😰 You must rinse it well after you apply it on your washed wet hair, and you def don't mix it with hair oil. It's a popular product here, but some ppl claim that it makes their hair greasy even though they use it correctly and rinse thoroughly after applying it on their hair. Here's a vid you can check out. A hairdresser testing it out to see why it gets too heavy and greasy for some ppl. And his conclusion is that when applying the product on your hair, you shouldn't apply it near the roots of the hair (and avoid your scalp ofc), for some ppl a few inches from the tip of hair is enough to use. Definitely never ever leave it on. Most Japanese wash hair everyday, it's recommended by hairdressers/stylists here in Japan for our kind of hair, unless you have issues ofc, and even so, this hair mask can make some hair oily or sticky if used too much amount, or too often. So please, please, used it correctly. It's bad for your hair and scalp to leave it on dry hair like that. If you have a Japanese friend, please ask her to read the instruction in the back of the product for you. I'm wondering how this wrong method is going spreading on internet?? kzbin.info/www/bejne/eqjEnYVmq72fgsksi=aNcYQ3idaExAABti At 3:28 he starts to apply Fino on a girl's hair then washes it off thoroughly if you keep watching Great choices of products you got btw. Thank you for your attention 😊
