Many ask Why won’t my hair stay straight after I straighten it!? There are several reasons why your hair isn’t following your grand plants. Here, we’ll discuss these reasons and how to keep your hair straight for a longer period of time.


Why Won’t My Hair Stay Straight After I Straighten It? Answered!

Some women think that their hair isn’t staying straight because of their genes which give them natural, strongly curled hair.

Women with kinky and curled hair can still manage to make their hair straight for a few days. If your hair isn’t staying straight after you straighten it, you’re doing something wrong.

If your hair isn’t staying straight after you straighten it, you’re doing something wrong.

Here are some reasons your hair isn’t staying straight:

1. Your Hair wasn’t Dry

Although water is necessary for hair care, it’s the archenemy of straightened hair. The smallest drop of water or other moisture can make your hair frizzy.

And it doesn’t matter if you just straightened it. 

In addition, straightening your hair while it’s still wet will do you no good. In fact, not only will you not get your hair straightener, you will be causing serious structural damage.

Straightening your hair while it’s damp will result in burning, breakage, and coarsen the natural texture of your hair.

It would be best if you only used a flat iron on your (towel-dried or mildly blow-dried) damp hair when using a wet-to-dry flat iron.

2. You Used too much Hair Product

Using hair care products is great. But it becomes a problem when you overload your hair with too much product just before straightening it.

Most of these products contain water, which negates the flat iron’s effect and can make your hair frizzy.

The more hair product you use on your hair before straightening it, the higher the chances of your hair curling up faster than you want it to. 

3. Your Flat Iron wasn’t Hot Enough

Your flat iron needs to be hot enough to achieve the desired effect. If it isn’t, your hair will retain more of its natural texture and won’t stay straightened. This is why it can be helpful to choose a flat iron with an easily-adjustable temperature setting like the BaByliss Pro we reviewed.

Keep your flat iron between 350 and 375 degrees to achieve straight hair with a fine texture.

Thicker or more coarse hair will require a temperature between 400 and 450 degrees. 

4. Your Hair Needs to be Trimmed

The ends of your hair are the oldest and drier than the other parts. The drier and more damaged the ends of your hair are, the harder they’ll be to straighten. They will also revert faster to your natural hair texture than healthy strands. 

To know if your ends are the problem, pay attention to your hair and take note of the areas that revert after straightening your hair. If the reverted areas are restricted to your ends, this may mean you need to trim the ends.

How to Keep Your Hair Straight for a Longer Time

Since you now know why your hair won’t stay straight after straightening it, we can move on to discuss how to stop your hair from reverting. Use these tips to help your hair straight for a longer period.

1. Take Time to Blow-Dry Your Hair

Don’t rush the process of blow-drying your hair. Take time to get your hair dry before trying to straighten it. The straighter your hair gets while blow-drying, the straighter your hair will be when flat ironing it.

It will also remain straight for a longer period.

2. Work in Small Sections and Go Slow

When straightening your hair, divide it into smaller sections and slowly move the flat iron downwards, from the root to the tip. Straightening your hair in small sections will ensure an even heat distribution, and no part is missed.

Slowly moving the iron down your hair will ensure each strand of each section gets enough heat to be perfectly straight.

3. Use Anti-Reversion Products

These products come in different ways, such as shampoos, conditioners, and creams. Using anti-reversion products before and after you flat iron your hair will ensure that it has the highest moisture content it needs and will not try to reabsorb moisture from the environment. 

Spraying your hair lightly with a great anti-reversion product after straightening it will keep your hair straightener for days. 

How to Keep Your Hair Straight During the Day

  • Use a wide-toothed comb. Carefully comb your hair with a wide-toothed comb. These combs discourage breakage and frizz.
  • Try a ponytail. You may tie your hair in a loose ponytail if the day is particularly windy. This will prevent your hair from being messed up.
  • Carry an umbrella. Keep an umbrella handy, especially if there’s a chance it could rain.
  • Use strengthening shampoos and conditioners. These products will keep your hair strong and healthy in-between treatments.

How to Maintain Your Straight Hair Overnight

Spray your roots with dry shampoo before going to bed. The shampoo will help absorb any excess oils and sweat you secrete while you sleep. Comb your hair to one side, securing it with bobby pins as you go. 

Sweep your hair all the way around, so it is wrapped around your head. After your hair is in place, wrap a silk scarf around your head to protect your hair from being frizzy and to reduce friction.


Your hair can remain straight for several days if you use the right products and take the necessary steps. When straightening your hair, use a heat protectant spray. It will provide a barrier between the flat iron and your hair, sealing in the moisture and discouraging frizz.

Every hair type can be straightened and can stay straight if the right technique, care, and products are utilized.
