I think you should really think about where you'd like to be before switching right back to natural. I've seen tons of relaxed heads on this board with strong, healthy, beautiful relaxed hair. You just have to find a regimen that will help you keep it that way, and stay consistent with it.
You'll have some type of issue with either relaxed or natural hair. Even if you decide to go back to natural again, you might still have the single knot issues .Whichever one you choose, you'll have to learn to work with it. jmo
