Hello, I've recently big chopped and need advice on products to use to maintain health of my hair.

When you big chop your hair is probably, most likely dry so the first thing you can work on is moisture. Find a moisturizing leave in like Kinky Curly Knot Today and use moisturizing oils like coconut oil. You could also use vitamins to help your hair health. You can use Biotin, Hairfinity, and The Mane Choice's Manetabolism.
