Well I sat in the steam for a while with the oil on my head, and I will say that even though my hair feels FUNKY (I still can't figure out what it is.....) I do see some tiny little red highlights coming through all over... and let me tell you, on black hair, even these tiny, subtle, little highlights make all the difference! I don't know if it was the oil or the Prell, but I don't think I will be using the Prell again. I'm going to do a vinegar rinse today & I'm going to go easy on the conditioner. I forgot to mention that I used Nexxuss keraphix conditioner for the first time after the Prell wash... this is a pretty heavy conditioner, and I feel it may have contributed to my funky hair.
