Please recommend a good product to soothe frizzy hair.

Among celebrities, there is Kim Won-hee, you know.

When you look at Kim Won-hee, her hair doesn't flow smoothly but instead has a style where it flutters in clumps.

My hair turned out exactly like that.

Since my 30s, I haven't dyed or permed my hair and have just left it natural, but it was gradually turning into straw.

I'm still worried about damaging my hair, so I waited until I felt like I was going to be called an old lady before dyeing my gray hair, but I'm even more worried about the future.

Is there a product that can coat my flyaway hair strand by strand to make it silky smooth? Is that asking too much? T_T
