04. BaByliss IPro Slim

Buy From Amazon

Let’s be honest, for few women ironing the hair is the most difficult task.

That’s why I have to introduce Titanium Pro from the BaByliss brand.

Why? Because Babyliss Pro is a hair straightener that gives us professional results, in less time.

Its main advantage over other hair irons is that this iron comes with a built-in comb (removable) that help you untangle your hair while you use it.

06. Remington Smartpro Sensor Technology

Buy From Amazon

Remington is one of the most popular brands in body care products. Their hair straighteners are appreciated all over the world.

This Remington S8598S flat iron also receives a lot of good reviews, but we do not settle for the opinions of others, so we bought this product and we analyzed it thoroughly. From design to features, from functions to package contents, we did not miss anything and at the end, we pulled our conclusions.

Let’s start immediately with what is the appearance of this gorgeous hair straightener.  The length is approximately 110mm, certainly above average but that doesn’t make it less comfortable. It has anti-scald rounded tips, and its lightness along with its ergonomic handle makes it a pleasure to hold in your hands. The power cable at the end of the plate is of an average length, but the most important thing is that it is rotating, so you will not have to worry about twisting and tangling it.

Good accessory kit

In addition to the beautiful Remington S8590 hair straightener, we also find a convenient travel case. The case doesn’t heat up and you can put the flat iron inside even immediately after using it. As far as the security is concerned, the flat iron is equipped with a safety lock to lock the plates, both while heating and when we carry it around so that even if you forget to switch it off, the hair straightener will turn off automatically after 60 minutes.

On the side of the flat iron, there are both the keys for the ignition and the keys to adjust the temperature. Speaking of ignition, the flat iron is really fast in heating, in just 15 seconds it is able to reach the desired temperature. The temperature is also shown on the digital display and can be selected from the following: 160 °, 180 °, 200°, 220° and 230° C. The lowest is recommended for thin and brittle hair, while the higher ones for thick and frizzy hair.

So let’s move on to the practical test of the Remington S8590, as mentioned previously the flat iron is long and very light, but the most important thing is that it flows through the hair with incredible simplicity.

Excellent results

The results that can be achieved by using this hair straightener are really surprising. This is due to the quality of the materials with which the flat iron is built. They are made of ceramic and keratin, two materials that combined together can protect the scalp with a 100 % guarantee. In addition, the plates are equipped with a sensor that protects against excessive heat, which, if it detects poorly hydrated hair, automatically lowers the temperature, for further protection of the hair.

To conclude the Remington S8598S hair straightener is a product with truly appreciable qualities, all the good that is said around is verified by Flatironpoint. Although a mid-range product but with a very high quality-price ratio. The ceramic and keratin plates, combined with the Heat Protection sensor, guarantee absolute protection for the scalp, while the ceramic stretches the hair with its innate properties, a product suitable for both home and professional uses.

07. Rusk Engineering CTC Technology

Buy From AmazonIf you have natural African American hair and you are looking for a hair straightener then RUSK Engineering CTC Technology Professional Straight Iron is the best choice that you could have. Not every hair straightener is designed in a manner to deal with thick hair. Many would claim that this flat iron is capable of straightening Afro hair but they simply do not have capability to heat up to the level that is required to heat up your hair. We have analyzed over two dozen hair straighteners and we came to the conclusion that Rusk Engineering Flat Iron is a promising choice for straightening thick hair.


  • Has a ceramic heater and titanium infused ceramic plates
  • Professional 1 ¼” straight ceramic iron
  • Makes your hair straight, smooth, and shiny after use
  • The plates of this flat iron have a sol-gel coating on them, which helps in a smooth hair straightening process

I was amazed when saw her hair with a beautiful curly style, she told after I asked her that how she give shine and style to her hair. Then she disclosed that she used a very qualitative flat iron made by Conair.

So this forced me to write a complete review of this amazing product and share some of the important features, facts as well as pros and cons of this amazing hair Straightener.

Conair Infiniti Pro Size
