I have been successful with Target's Curls Curl Creme Brûlée. I have 4a hair, a bit similar to yours but maybe thicker. Trick is is to put product on soaking wry hair ( I invested in a mirror for my shower wall). Use your fingers to rake through hair (no combs or brushes) and maybe put about 1 to 2 tbsp worth of
Product. Shake your hair to loosen curls and let air dry. Do NOT touch hair. Try it and let me know.
