How to get curls like this?

First of all I recommend using frizz-ease hair serum then make sure you have a good quality curling iron use heat protectant and curl each piece for about 10-20 seconds depending on how thick your hair is then evenly spray some hairspray nit to much or I'll got dry and crispy but enough to keep it in place.

Apart from having hair like Richard naturally I can only think of a curly perm. If you have frizzy hair use a leave in conditioner. Never brush dry
