Frequently Asked Questions And Buyers Guide

Frequently Asked Questions and Buyers Guide

Many users always have questions on how they will get maximum benefits from the straighteners. I have managed to answer most of their concerns and gone further to provide extra tips.

How do I know if I have thick hair?

This may look like an easy thing to identify but do not confuse dense and thick hair. The thickness of the hair is measured by the diameter of one’s individual hair strands. Therefore, it is essential to know the difference between dense hair and thick hair to avoid making mistakes when you are purchasing a flat iron.

You can know whether your hair is thick by placing a single strand between your fingers then pull it. If you feel the impact, then your hair is thick. If you do not feel anything, you probably have thin hair. So make sure you identify your hair type first before proceeding to buy a flat iron.

What features should I consider when buying flat iron for thick hair?

With so many hair straighteners in the market, it gets hard to find the best one for thick natural hair that does not damage your hair, has a perfect range of temperatures, and is perfect for styling your hair. Maybe you once compromised some of the qualities you were looking for in flat iron.

This should not be the case at all. You should be able to find an iron that checks all your requirements. You need to determine the hairstyle you want. Is it curly, straight, or flip? This way, you will specifically look for a flat iron that performs these functions. Also, be aware of the level of heat your hair can withstand so that you can know the temperature range you want the flat iron to have.

Additionally, you should find a flat iron that can reach a maximum heat of 400 to 450 degrees. Negative ion technology is an added advantage for any flat iron as it leaves hair looking smooth and shiny.

Lastly, check whether the plates are ceramic or titanium covered. These materials relay heat fast, and therefore you will do your hair quickly. If you have been asking yourself, what is the best flat iron for thick curly hair? Then these features directly answer your question.

What are the best hairbrushes to use while straightening my hair?

Many brushes talk significant about their perfect performance, but they do not work according to the given description. You can get the following brushes to straighten your hair. Remington Pro 2-In-1 Heated Straightening Brush, InStyler Straight Up Ceramic Straightening Brush Glamfields Hair Straightening Brush, and Revlon XL Hair Straightening Heated Styling Brush are my top four brushes for straightening hair.

How do I curl thick hair with a flat iron?


Using a straightener to curl hair should create full, bouncy curls. It takes a little practice and effort, but you will get around it soon. You can follow this procedure to get the curls you have always desired.

First, wash and dry your hair. Damp hair will not curl perfectly, while dirty hair will not hold the curls well or for long. Go with the 1-inch flat irons.

Anything more than this is suitable for straightening hair. Also, choose the ones with round edges to get those circular curls. Divide your hair into sections and start from the back. Hook your comb on the hair then follow it carefully behind by clasping the flat iron on the hair right from the roots. Ensure you do not get too close to the scalp to avoid being burned.

Twist the hair in the opposite direction to get the volume you want. Release every curl and let them fall loosely. The secret to getting good curls on thick hair is to keep the iron moving and avoid wrapping hair around it. After you are done, brush your fingers through to ensure the waves are even.

What Product Is the Best for Me?

Although it wasn’t in my top five list, CHI is among the most popular brands in the market for hair styling products. So, according to the characteristics mentioned above, you can get yourself the best CHI flat iron for thick hair if you are a loyal CHI customer. Your hair should not let you down, especially after you have had your nails and makeup is done, and you are rocking in that nice dress.

The least you can do is to give your hair some life with one of the flat irons discussed above.
