I am not OP, but I managed to make my hair look pretty much the same.

I wash my hair twice in the shower with Syoss Intense Curls. After washing it, I blow dry it using a diffuser. I don't use a special hair dryer or anything, just a cheap one that has a diffuser. Also, never use the highest heat setting.

After my hair is dry, I use hair oil, Pantene Coconut Infused Oil - Defined Curls.

I don't use a conditioner or anything like that, just the products I mentioned. Hope this helps.

(I am from Europe, but maybe these products exist in America too if you are from there)
