Having coarse, thick, curly hair could be a challenge when it's time for something new. If you are looking to have bone straight hair without the cost of expensive hair salons or harsh unknown chemicals, you can pick what works for you and do it yourself in the comfort of your own home, bathroom, living room, or dorm room! The products necessary are very affordable, it could take less than 90 minutes (depending on how much hair) and you are aware of what is being used in your own hair. Many go to the professionals, but if you're a busy person on a budget, doing it yourself works just as well!

Warning: Please use these steps as a guide according to your hair texture.

Step 1: Gather Materials

You will need:

Hair clips or hair ties
A mirror
Heat protecting spray
A spray based leave in conditioner of your choice
A flat iron with temperature control and width of your choice (preferably 1.5 inches)
Blow dryer
Deep conditioner of your choice
Shampoo of your choice
Plastic cap
Paddle brush
Wide tooth comb or skinny tooth comb depending upon hair texture

Step 2: Shampoo

Use a shampoo of your choice to wash and rinse 2-3 times.

Note: It is best to use a wide tooth comb to detangle in between each wash.

Step 3: Deep Condition

Section and apply a deep conditioner of your choice thoroughly onto the hair, starting from ends to roots.
Apply plastic cap and let sit for 10-15 minutes.
Rinse out deep conditioner and detangle with a wide tooth comb.

Step 4: Detangle

Depending upon the thickness of hair, section in as many parts as needed.
Use a wide tooth comb to detangle.

Note: It is recommended to comb from tips to roots.

Step 5: Blow Dry

Apply a spray leave in conditioner of your choice.
Use as many clips or hair ties necessary to section hair and completely blow dry from root to tip.

Note: Side ways blow dryers work well with naturally curly or coarse hair. Additionally, the temperature for the blow dryer should be adjusted according to hair texture. Thin and damaged hair is suggested to use low heat setting, whereas, thick coarse hair is suggested to use medium to high heat setting.

Step 6: Sectioning

Create several small sections in your hair (right picture) or create one big section holding it with a hair tie or clip at the top, and just pull out small sections as you go (left picture).

Note: Section size and the amount of sections may vary depending upon the amount of hair.

Step 7: Straightening

Once you've cleaned, detangled, dried, and sectioned your hair:

Turn on flat iron to the temperature of your choice, depending upon your hair texture.
Take a small section (about an inch and a half) of hair out.
Holding the hair in one hand, use the other hand to apply heat protecting spray from root to tip.
Take the flat iron and start from the roots, slowly move down to the tip of the hair.
Repeat this step until all sections of the hair is completed.

Step 8: Finishing Touch

Once every section is completed and flat ironed:

Take your paddle brush and/or skinny tooth comb and brush through from root to tip.

Note: You may add any additional sheen spray if necessary, but if the heat protecting spray is a good one, no additional sheen would be necessary.
