Your Hair Gets Smooth

With these shampoos, you will notice that your hair gets a lot smoother. They look a lot glossier, and you can make different hair-dos easily. Plus, your hair-dos will look sleeker and will last longer. You can style your hair to make your curls and waves last longer. 

What Makes a Great Straightening Shampoo?

These straightening shampoos are best used to smooth the hair and make them sleeker and more manageable. Now the market has a number of options available, so how can you know if your straightening shampoo is any good? Well, here are a few things that your shampoo must be doing for you.

Your Curls Should Not Show up

Your shampoo must be able to weigh down your hair so that your natural curls or waves do not form. Your hair must be straight after you’ve washed them, and the straightness must last for a longer period of time.

More Manageable Hair 

If your shampoo is taming your hair and making it more manageable, then that’s a good sign. It should make it easier to de-tangle your locks, and you should be able to style your hair with a comb easily. 

You Shouldn’t Require Too Much Heat 

Since your hair is already pretty straight after using the straightening shampoo, you should not need to spend a lot of time straightening them with a flat iron. You should not have to use the blow dryer and flat iron for a lot of time, which will reduce the risk of heat damage as well.

You Should be Able to Incorporate it Into Your Daily Routine

Your shampoo should be easily available. It should be budget-friendly, and it should most importantly suit you so that you can incorporate it into your daily hair routine.

People Also Ask

Even after all this research, you might still have a couple of questions in your head that might be stopping you from making a purchase. Well, here are a few common questions that arise so that we can clear up your doubts and ensure a good hair straightening experience. 

Does Keratin Shampoo Straighten Hair?

While a lot of hair straightening products have the word keratin in their name, it is safe to say that keratin is not the main ingredient that straightens your hair. The only way to straighten one's hair completely is through heat or chemical treatments in which the hair’s inner disulfide bond is broken. Keratin shampoos cannot straighten the hair!

Can Coconut Oil Straighten Hair?

To straighten your hair naturally, you can opt for hot oil therapy. You can use hot coconut oil on your hair to make it smoother and straighter. Simply heat up the oil, apply it on the hair, then take a towel dipped in hot water, squeeze it, and then wrap it around your head similar to a turban. Keep it on for about five minutes, and repeat this step 4 to 5 times. Wash off using a mild shampoo and use a wide-toothed comb to comb through your hair. Do this twice a week for better results.
