My results were amazing but the after damage was HORRIBLE! It took about a year to fully come out and once it did my curls went from 3c/4a to a stringy straight pattern with a slight wave. I would suggest for you to look up YouTube videos on people's experience. If you want straight hair and plan on redoing it it, then I would recommend it. But if you're looking for a temporary treatment and want your curls fully reverted back, then I would not recommend it.
