Flat Iron for Gray Hair | Top 5 Flat Irons & Guide to Select the Best

Are you going gray? I bet you are stressing over how to heat style your hair. After all, gray hair is more prone to damage.

Gray hairs are more porous in nature. They don’t have their own pigmentation or color. Moreover, the heat damage caused by flat irons is more visible in gray hair in comparison to colored or tinted hair. Heat damage can also leave your gray hair to pale yellow color.

Having gray hair doesn’t mean saying goodbye to heat styling. You can still straighten it and style it in your own way. You just need to find the best flat iron suitable for your gray hair.

A good flat iron can save your sparkling silvers. Here is a detailed guide to help you find the best flat iron for gray hair.

How to Select the Suitable Flat Iron for Gray Hair?

1. Go for flat irons with temperature adjusting features

Higher is the heat, the straighter and sleeker is the hair. But not all of the hair types need or can adjust to high temperatures, especially gray hair.

Make sure the flat iron offers multiple adjustable heat settings. This will give you the freedom to decide how much heat you want to put in your hair.

Set the flat iron to its lowest temperature or the lowest heat setting to unlock straight, silky, and frizz-free and damage-free gray hair. Also, try to make only a few passes.

2. Choose the right plate for gray hair

As mentioned before, gray hair is porous and more prone to breakage. Styling it with flat irons can make them frizzy, rough and burnt.

Choosing a flat iron with the right plate can save you from such unwanted results of heat styling. While different flat irons are made of a combination of different materials, some are less damaging to your hair than others.

The best plate option for gray hair is definitely ceramic plates. These plates control heat and distribute it evenly throughout your hair strands. Such plates are either ceramic plates or ceramic coated.

Titanium plates are used for distributing higher temperatures. These plates get heated up real quick and are more suitable for extremely coarse or textured hair.

However, ceramic plates are the best if you want to keep the heat minimal and save your silver locks from getting overheated.

3. Treat your flat iron as an investment

It’s easy to fall for cheap flat irons when you are searching the shelves for your next heating tool. Cheap flat irons can break easily, fail to give great results and even burn your hair.

Don’t risk your gray tresses by going for a flat iron that is unbelievably cheap. Take your budget into consideration and make a purchase that is not overtly costly yet provides great value and quality.

We have some great recommendations you can consider while choosing your best flat iron for gray hair.
