Hello Siphe
Sure you can do S-Curl. Ensure you are taking the best care of your hair and use a Dark and Lovely Moisture PLUS relaxer to have this done. To care for your hair, shampoo your hair weekly using Dark and Lovely 3 in 1 shampoo and Deep Conditioner. Dark and Lovely Light Oil Moisturiser is perfect to keep your hair hydrated and can be used daily.
Warm regards
