6 Tips for Straightening Thick Hair

5 Tips for Straightening Thick Hair

To straighten thick curly hair is a chore. Those who keep their thick tresses straight and gorgeous must undergo a lengthy drying and styling process.

Thick and curly hair take a lot of effort and patience to style, especially if you want a precise pin-straight look. It doesn’t have to be that horrendous, though. 

Below are five tips to remember when it comes to straightening thick and curly style hair:

Tip 1. Make sure hair is completely dry

 Wet hair and heat do not mix, so make sure your hair is totally dry before using the straightener. You can achieve this by air-drying and blow-drying your hair. 

Tip 2. Use hair oils instead of pre-heat treatments

Although heat-protecting serums and sprays are promising, experts suggest oils are better as they absorb into the hair than just coat the hair. 

Tip 3. Find The Right Straightener Size

Having the right straighter size can help you immensely when straightening your thick hair. Plates for flat irons or straighteners come in a variety of sizes. 

Generally, the larger plate irons are the ones you should use; as a result, you will cover a broader area in less time.

Your hair length can factor in your flat iron size too. Check the guideline below as follows.

  • Thick hair that is shoulder length or about – Go for 1 ½-inches wide.
  • Thick hair that’s shoulder-length and longer – opt for an iron with plates between 1 ½- and 2-inches wide.

Tip 4. Choose an Iron with Variable Settings

Some straightening irons only have three heat settings: low, medium, and high. It is, however, preferable to use an iron that allows you to set the temperature precisely. 

Thick, coarse hair straightening temperatures range in-between 350 and 400 degrees; thus, an iron that can let you adjust your temp accordingly helps prevent over heat-treated hair.

Tip 5. Use a Brush, Not A Comb

Next time when straightening your hair, try using a brush instead. A comb on dry hair can oddly cause split ends and static.

Tip 6. Work In Sections

One of the best ways to get thick hair straight is to divide it into small workable sections. Begin by dividing your hair across, clipping the top section to the top of your head. 

Depending on the size of your iron plates, divide the lower half into portions that are about 1- to 2-inches broad. 

Straighten each section from there. Next, release your top section taking one a small section at a time.
