DIY ombré 1. Pour sun-in into a cup, dip hair and straighten with a flat iron (heat activated). 2. Concentrate on bottom of hair and work your way up till about mid cheek. Keep in mind ombré needs to look gradual, so straighten it less as you go up. 3. Use clairol borne blonde for the tips of hair. Make sure the blonde is even in both ends! Voila!
