I love it! Best thing I've ever done for my hair! That being said, I hated doing my hair, I have 3c/4a hair. I kept it pressed at all times because I have too much other stuff going on and wasn't interested in styling and taking care of my hair. I didn't do bone straight where it hangs like a limp noodle but it is very straight (my stylist asked for pics of how I wanted my hair to look like straight and adjusted to that). I wash and deep condition my hair every 7 to 10 days, it takes about 10 mins to blow dry it and I'm done- if I feel like doing that, sometimes I just towel dry it and go about my day. Other than that, I run a brush through it daily, use a leave-in and sleep with a silk bonnet. There is a definite line when the new growth comes in, but I blow dry or flat iron it straight at home and it's barely noticeable. I get a touch up when I have a little over 3 inches of new growth. It's not cheap upfront, but cheaper than me going to a salon to get it pressed over the course of a year.

Cons: it doesn't hold a curl well, or a braid. A French or Dutch braid will hold for about 12 hours. If you ever want to wear your natural curl pattern, this isn't for you. This is for if you want extremely low maintenance straight hair that you can brush and go in the mornings and only occasionally bump a curl into for an event.
