How long does it take to straighten hair?

Preparing Your Hair

1.1. Clean and Dry Hair

Start with clean, dry hair as wet or damp hair can take longer to straighten and may cause damage due to excessive heat exposure. Ensure your hair is fully dry before beginning the straightening process.


1.2. Detangling

Before straightening, detangle your hair using a wide-toothed comb or a detangling brush. This step helps prevent breakage and ensures smooth, even results when straightening.


1.3. Applying Heat Protectant

Apply a heat protectant spray or serum to protect your hair from heat damage. This step is crucial to maintaining the health and integrity of your hair while straightening.


Sectioning Your Hair

2.1. Hair Length and Thickness

The length and thickness of your hair will determine the number of sections needed. Longer and thicker hair will require more sections to ensure that each strand is evenly straightened.


2.2. Section Size

The size of the sections will depend on your preference and convenience. Smaller sections allow for more precision but may take longer to straighten, while larger sections can speed up the process but may result in uneven straightening.


Straightening Methods and Tools

3.1. Flat Iron

Using a flat iron is a common method for straightening hair. The time it takes will depend on the length, thickness, and texture of your hair. On average, straightening hair with a flat iron can take anywhere from 10 to 30 minutes, depending on these factors.


3.2. Hair Straightening Brush

A hair straightening brush combines the benefits of a brush and a straightener in one tool. The straightening process with a brush can be faster compared to a flat iron, usually taking around 5 to 15 minutes, depending on the hair length and thickness.


3.3. Blowout or Blow-Drying

A blowout involves using a blow dryer and a round brush to straighten the hair. This method requires more time and effort, especially for longer and thicker hair. On average, blowouts can take anywhere from 20 minutes to over an hour, depending on the hair length and texture.


Hair Length and Straightening Time

4.1. Short Hair (Above Shoulder Length)

Shorter hair is generally quicker to straighten compared to longer lengths. On average, it can take around 10 to 20 minutes to straighten short hair, depending on its thickness and texture.


4.2. Medium-Length Hair (Shoulder to Mid-Back Length)

Medium-length hair requires more time and effort to straighten compared to short hair. It can take approximately 20 to 40 minutes to straighten medium-length hair, depending on its thickness and texture.


4.3. Long Hair (Past Mid-Back Length)

Long hair takes the most time to straighten due to the larger amount of hair to work with. On average, it can take around 30 minutes to over an hour to straighten long hair, depending on its thickness and texture.


Post-Straightening Care

5.1. Cooling Down

After straightening your hair, allow it to cool down before styling or touching it. This helps to set the straightened style and prevents the hair from frizzing or losing its sleekness.


5.2. Post-Styling Time

The time needed for any additional styling, such as adding shine serum, applying hairspray, or styling your hair into a specific look, will vary based on your preferences and the complexity of the style you want to achieve.


Frequency of Straightening

6.1. Heat Exposure Considerations

To minimize damage, it’s important to limit the frequency of heat styling. Excessive heat exposure can cause dryness, breakage, and other forms of damage. Aim to straighten your hair no more than 2 to 3 times a week and utilize heatless styling methods on other days.


6.2. Straightening Maintained Hair

If you have previously straightened your hair and it has maintained its straightness, subsequent straightening sessions will require less time. Touch-ups may be necessary to smooth out any minor waves or frizz.



The time it takes to straighten hair depends on various factors, including hair length, thickness, texture, and the chosen straightening method or tools. By properly preparing your hair, sectioning it effectively, and using the right tools and techniques, you can manage your time efficiently and achieve beautifully straightened hair. Remember to consider post-straightening care and limit heat styling frequency to maintain the health and integrity of your hair. With practice and patience, you can create a sleek and polished look while minimizing damage and maximizing the longevity of your straightened style.
