I read other reviews how this may not suit the needs of other hair types, which is why the line of natural products differ to tailor different hair needs.
I tried the Nourishing Moisture kind first, which did improve my hair compared to higher sulfate and silicone content. Then this came out, used it after I was done with the moisture one, and there was a difference there as well. Curly hair needs more natural oils present to retain moisture & strength and jojoba oils are great at mimicking those. I've used this product for over a year & I refuse to use anything else. Like I said, not sure if it works as well on other hair types, but for the price vs. quality, this is DEFINITELY a good buy for curly hair.
