How to Straighten Curly Hair

What to Look for When Buying the Best Straightening Shampoo (Buying Guide)

Are you ready to get smooth straighter hair? The best shampoo can make your hair look straighter, feel smoother, and look more moisturized too.

Check these out first before buying hair straightening products.

1. Check the ingredients

The best brands contain natural and organic substances. But some brands may contain some synthetic substances such as silicone and sulfate. Sulfate can be drying but they make a shampoo easier to lather. So if you already have dry hair you might want to avoid this.

Silicon, on the other hand, can help straighten the hair. But if you’re allergic to it, avoid it at all costs.

2. What’s your hair type?

The best straightening shampoos have different formulations. Some brands may contain a lot of hydrating oil blends. That works great for dry and dehydrated hair, but they can be too much for your oily hair.

A lighter formulation will benefit your oily hair. But it can be undernourishing for dry and dehydrated locks. You have to do your research and check what brands are compatible with your hair type.

3. Check reviews

Reviews allow you to see the experiences of other people. So make some time to scour the net and look for legitimate reviews. This will make you decide if what brand best suits your hair type and hair needs.

What is a Hair Straightening Shampoo

Hair straightening shampoos can make your hair sleeker and smoother. This type of shampoo helps you get rid of the frizz, the tangles, and the knots.

But does that mean that it can take the place of your hot tools? Not necessarily. It can help smoothen out your hair. But it won’t necessarily transform your luscious curls to super straight hair. It instead helps your hair become more manageable so that your tresses won’t get all tangled up in your brush or comb.

It can make your life easier. And it would also prevent you from yanking your hair if it gets tangled up in your comb. That’s why a lot of girls have this in their shower. It can also help save them time in making ready for a hot date.

How Does A Hair Straightening Shampoo Work

Hair straightening shampoos won’t fully straighten your hair. But it can make it more amenable to styling. So you will spend less time brushing or even ironing your hair. How does it work exactly?

Regular shampoo and straightening shampoos look the same. The difference lies in the list of ingredients. Let’s take a look at some of the most common ingredients used in hair straightening shampoos. And let’s see how each works.

Silicone seals in the moisture in your hair strand and it also prevents moisture from escaping. So this allows the heat from your hot tool to easily reach the interior of your air. Thus, making it easier to style. 

2. Keratin moisturizes your hair and makes it softer and smoother. It also removes frizz and flyaways. This will make your hair tangle-free and seem straighter.

3. Different brands use different types of oils. But coconut oil seems to be the most popular. And it may be the most nourishing oil from the rest. This rich oil can cover your hair with a layer of ultra-moisturizing compounds. 

This makes your hair softer and it also removes the frizz. So it’s easier to comb your hair and it won’t get tangled up.
