Blowdrying hair.
For curly hair
Some tools are needed. Wan
t full and thicker hair?
After shampooing and conditioning towel hair dry very well and comb it out with a wide tooth comb. Start combing the hair from the ends up not from the roots down. Once hair is all combed out section the hair. First into two parts with a part down the middle of the head then into four with a part across the head from the back of one ear to the other ear. There should be four sections, twirl each section of hair and use a clip big enough to hold the hair all together.
Starting with one of the sections from the back of the head remove the clip and divide this section into two by taking one of your fingers and running it across the section sideways at about the middle of the section. Clip the top part of the section and let the bottom hair fall free making two sections out of the same amount of hair. Now you are ready to start blow drying the hair that is free. Continue with the other section and continue through the rest of the other three sections by dividing them all into two this means the whole head will have been divided into eight sections all together. Its always fine if the sections still get divided into more sections depending on the density of the hair you may need smaller sections in which case from the original four one can make twelve sections. 
For best results use an Ionic blow dryer.
Start with the section of the hair in the back that is loose. Using a round brush wrap the hair around it once and blow on the brush while puling the brush down this will give the hair a feeling of elasticity. The idea is to dry the hair is is pulled straight by lowing directly on it. One must do this a few times on the same peace of hair until it is fully dry. Once this section is dry move to the other section over it. Do the same on each section of hair going from back to front, if the front of the hair is dry by the time you get to it than wet the hair again because if the hair is not wet enough you will not achieve the best results.
Straightning your hair with a flat iron.
Blowdrying hair gets the hair straight but for very straight hair and flat one must use a flat iron after.
For best results take a section only as wide as the iron and about an inch thick. Start as close to the scalp as possible without touching the scalp as this will burn the scalp when it comes in contact with it.
Start on one side of the head and finish on the other.
