Natural Hair Straightening Products Buyer’s Guide

How do you choose the best straightening products for natural black hair? You start by determining the straightening method you’ll use, then find a suitable product for the procedure.

Applying a heat resistant spray and a hair relaxer is entirely different, so let’s get familiar with the most frequent straightening procedures for natural hair:

Heat Straightening

stylist flat ironing hair

Everyone knows the most common straightening method: a flat iron or hair straightener. Even ladies with straight hair own these tools because the final result is so alluring.

It’s hard to stay away from hot tools because they give you the liberty to straighten hair, create beach waves and voluminous curls. All you need to do is spray a heat protectant and start going over each strand.

Straighteners and irons are straightforward to use, the latest releases cause minimum damage, and can be very affordable purchases.

The downside is that this isn’t a permanent result. Each time you wash your hair, you’ll have to straighten it all over again. This means more extensive damage in the long term.

The hair straighteners and irons with the most advanced features are usually more expensive but cause less damage because of their innovative technologies.

Relaxing

phytospecific relaxer before and after

Getting a relaxing hair treatment is a popular option among ladies with curly hair. It includes applying chemicals that act on the hair follicle and make your hair straighter.

The results are permanent and last until your hair grows out. This is definitely a great solution for curly-haired women who want straight hair, and it makes it easier for them to experiment with various hairstyles.

One of the biggest cons of relaxing treatments is that they use chemicals that cause hair damage. Yes, you’ll enjoy your relaxed hair for quite a while, but at one point, you might need to cut it shorter to deal with the damage.

Another thing to know is that these procedures tend to be costly. If you still decide to try hair relaxers, ensure that you find a skilled professional who knows what they’re doing.

Keratin

Keratin treatments are growing more popular by the hour. They are currently highly requested and come in several versions. Getting a keratin treatment means that a hairdresser will apply chemicals on your hair that will straighten it, make it glossy and smooth.

These chemicals aren’t the same used like the ones in the process of relaxing. Keratin treatments last up to six months.

Some salons use keratin formulas that contain formaldehyde which is a potential carcinogen chemical. Another con of this method is the costly nature and that you’ll have to stay away from chlorinated water, including pools.

Hot Comb

hot combs

Hot combs look like regular combs, with the only difference being that they release heat and can straighten your hair. These tools are convenient to use and can be beneficial for ladies with natural short to medium hair.

However, a hot comb can sometimes be dangerous because you can burn yourself if you don’t pay attention. One downside you need to know about is that this tool isn’t the best choice for very long, coarse hair.

Blow Drying

Straightening your hair with a blow dryer is a time-consuming task; however, it yields gorgeous results. When paired together with a great straightening blowout cream, this method can give you a silky-smooth hairdo with a stunning shiny finish.

If you want to achieve that polished look, you need to get a high-quality blow dryer and a brush. Ensure that your hair is damp, divided into sections, and start blow-drying small strands of each section until your hair is straight.

Although the final result is gorgeous and lasts a few days, doing this takes a lot of time. It’s a less damaging alternative than chemical treatments, but you can end up with dry, lifeless hair if you do it often.
