First coat your hair in some form of heat protectant and set your straighteners on a low heat! This is how I always straighten my hair. Then, using a fine tooth comb, comb through sections of your hair following through with hair straighteners. This helps to straighten more thoroughly and smooth down the hair cuticals resulting in less damage & breakage to the ends of your hair.
Finish with the hair accessories of your choice! I think tiny flower or bow clips through the braids would look quite pretty!
After care: When you are finished with your braids, gently undo them. Softly seperate the teased hair with your fingers. Avoid brushing it out! Brushing it out will cause breakage and hair to fall out. Go straight to the shower and massage through a detangler/ conditioning treatment and very carefully comb out the tangles with a wide tooth comb. Then treat your hair to some TLC and give it a conditioning treatment! :D
