Be Very Carefull What Shampoo You Use....Find One That Is Salon Quality..NOT Pantene...ThermaSilk..Tresomme...Dove or Similar...I Would Actually Recommend Either Matrix "Sleek Looks" or Redken's "SmoothDown" DON'T Brush Your Hair Wet To Detangle...Use Fingers And/Or Wide Tooth Comb or Pick......Do Use A Flat Iron After Blowdrying...Preferably A Ceramic Flat Iron....The 400 Degrees May Not Be Necessary Depending On How Fine Textured Or Chemicly Treated Your Hair Is....Think About Getting Your Hair Straightened...Get A Professional Consultation About The Options Avaliable To You
