Things To Be Aware Of When Straightening Gray Hair

Things To Be Aware Of When Straightening Gray Hair

There are a few things to be aware of when straightening gray hair.

The Material

When using a flat iron on gray hair, it is a good idea to opt for a product with plates made of glass or ceramic.

This makes the plates smoother so they can pass through the hair without any snagging. 

Ceramic coated with tourmaline is another good option if you’re using flat irons on gray hair. Tourmaline, a semi-precious stone, is ground and layered over ceramic plates. 

Tourmaline generates negative ions which help in replenishing gray hair and lock in moisture. The tourmaline technology means less heat is required to manage frizz in gray hair.

The Heat Setting

With gray hair, it is best to opt for a flat iron that has multiple heat settings. Ideally, you should go no higher than 300°F to protect your precious silver locks.

Multiple heat settings mean you will be able to choose the lowest heat setting that gives you the desired results without damaging your hair.

You should also try to minimize the number of passes you make with the flat iron on your hair to further reduce heat damage on fragile gray hair. 

Use Heat Protectant

Intense heat can break down the keratin in your hair; this can affect the hair’s texture and strength.

In other words- it can be very damaging for gray hair which is already susceptible to damage.

It is widely recommended that you use a heat protectant before using a flat iron on gray hair. This can come as a spray, a serum, or a cream. 

Heat protectant acts as a barrier between your flat iron and your hair, helping to seal in moisture and minimize damage caused by heat.

TLC

If you want to continue using flat irons on gray hair, you need to invest time in to showing your hair some love.

Apply a deep conditioning treatment or a pre-shampoo nourishing hair mask once or twice a week.

Try using treatments with coconut oil, aloe vera, or avocado as these are rich in moisture.

You should also avoid shampooing your hair every day as this strips away the scalp’s natural oils which your gray hair needs.

Invest In Quality

Avoid opting for a flat iron that is the cheapest available. These can be less reliable and even prone to damaging your hair.

If you invest in a styling tool, you are more likely to reap the rewards. Your hair will thank you for it!

How To Avoid Further Damage To Gray Hair 

There are several things you can do to avoid further damage to gray hair. 

Getting the right vitamins is important to keep gray hair healthy-A, B, D, and E are the vitamins that help with this.

You can also try to make sure you get enough minerals such as zinc and iron, as these play an important role in the growth and repair of your hair.

Avoiding smoking, covering your hair in the sun, and avoiding harsh shampoos are all further ways you can avoid further damage to gray hair.

So, if you’re looking for the best flat iron for gray hair, our round-up should help.

With the right tool and a little care you can enjoy beautiful silver locks for years to come
