15 Flat Iron Hairstyles For Medium Hair Black Girls – 2023

Here are more detailed instructions for popular flat iron hairstyles for medium hair on black girls: Divide hair into 1-inch wide sections from the top of the head down to the nape. Use a heat protectant spray on each section before flat ironing.

Starting at the roots, clamp the flat iron and slowly drag it down the length of the hair, keeping it as straight as possible.

How Do You Style Flat-Ironed Hair?

To style your flat iron hair? Follow these steps

Step 1: Prepare Your Hair

Start by washing and conditioning your hair thoroughly. Make sure it’s clean and free from any product build-up.

Opt for moisture-rich products to keep your hair hydrated and protect it from heat damage.

Step 2: Apply a Heat Protectant

Before using a flat iron, apply a heat protectant to your hair. This creates a barrier between your hair and the heat, minimizing the risk of damage.

Step 3: Section Your Hair

Divide your hair into manageable sections. This ensures even heat distribution and makes styling easier. Begin at the back of your head and work towards the front.

Step 4: Start Flat Ironing

Take one section of hair and glide the flat iron gently from root to tip. Avoid staying in one spot for too long to prevent heat damage. Repeat this process for all sections until your hair is straightened.

Step 5: Add Volume

For extra volume, lightly tease the roots of your hair with a comb. This lifts the hair at the roots, creating a fuller look.

Step 6: Apply a Finishing Product

Once you achieve your desired flat-ironed style, apply a finishing product such as shine serum, hairspray, or oil. This adds shine and helps your hairstyle last throughout the day.

Step 7: Maintain Your Style

To maintain your flat-ironed hair, wrap it in a silk or satin scarf at night. This prevents friction and helps retain moisture.

Remember, excessive heat can damage your hair over time, so give it a break from the flat iron occasionally. Use deep conditioning treatments and moisturize your hair to maintain health.

How Often Should A Black Girl Flat Iron Her Hair?

Start flat ironing from the crown, pressing the iron down at a slight outward angle rather than straight down.

This adds movement and dimension without frizz. Work in 1-inch sections, taking hair from roots to ends.

For the sides, angle pieces out and away from the face. Curl the ends of each section slightly under rather than holding them perfectly straight.

Lightly backcomb the roots for added volume before flat ironing smooth.

8. Beach Waves

Beach Waves

Divide hair into horizontal sections and flat iron each one, curling the iron gently and not pulling it taut.

Is It OK To Put Oil in Hair Before Straightening?

No, applying oil to your hair is not recommended before using a flat iron or other heat-styling tools.

Oil can conduct heat, making your hair more prone to damage. Straightening oiled hair can fry the strands, causing dryness, breakage, and split ends.

Some oils have a low smoke point, which means they can smoke and degrade when exposed to high temperatures, potentially releasing harmful fumes.

Instead, use a heat protectant spray specifically made for heat styling. These products create a barrier between your hair and the heat, reducing the risk of damage.

Ensure your hair is dry before straightening it because wet hair is also more susceptible to heat damage.


Flat iron hairstyles for medium-length hair in Black girls offer versatility and elegance.

Use proper techniques, heat protection, and hair care to maintain these styles. Healthy hair is key to sustaining these looks while celebrating the beauty of natural hair. Embrace the creativity and confidence of these hairstyles, expressing your unique style and personality.
