Please recommend a no-wash treatment product.

Since I usually have oily hair, I've been told that it looks bouncy and soft even without paying much attention to the texture.

However, after dyeing and perming my hair multiple times and passing my 30s, it is becoming dry and brittle.

I'm thinking of trying a treatment product to provide nourishment to my scalp and hair.

I saw the spray-on no-wash treatment product in your posts.

I'm looking for a product that's good for managing whenever I remember.

Please recommend any no-wash products you use that are non-greasy and leave a fresh feeling.
