Can hair dye cause hair loss ?

Dyeing hair has become a fashion symbol over the past years. People like to change the natural color of hair, as it looks more attractive. There is another factor for dyeing hair as well. As you start to age your hair loses their natural color and turn grey and it is impossible to avoid it.

Some people open-heartedly accept the natural grey hair, while others tend to die them. But can these hair dyes cause hair loss ?

Why is hair dyeing bad for your hair ?

In short hair dyes contain ammonia, hydrogen peroxide and many other chemicals in them that can lead to problems like hair loss. Those penetrate the hair and damage their outer layer, making them easily breakable.

Permanent and temporary hair dyes both have chemicals in them. If you want to dye your hair without any damaging effects or hair loss, you must select the dyes containing natural ingredients. Chemicals in dyes damage your hair structure and make them frizzy and dry.

How does hair dyes cause hair loss ?

There are different ways through which hair dyes can damage and weaken your hair shafts. Here the main culprits are the bleaching agents and chemicals in the dyes, especially with frequent colouring. Those are the conditions that can lead to hair loss.

Ammonia in hair dyes :

The cuticle is the outer layer of hair that protects the hair from damage; it is like the bark of the tress. The ammonia in hair dyes penetrates or lifts the cuticle to raise the pH level of hair.

Your hair is damaged the very moment when your hair is exposed to ammonia. Especially because the cuticle is not meant to be damaged or be penetrated.

The only purpose of ammonia is to break the cuticle. The uplift of the cuticle can lead to hair loss that is caused by hair breakage.

Use Of Peroxides :

After the cuticle is lifted, it’s time to dye your hair. The hydrogen peroxide in the hair dyes are used to give the desired color to your hair. The peroxide stays on your hair until the dye penetrates the hair shaft. Those also leave your hair dry and frizzy making them prone to damage.

The longer the ammonia and peroxide stays on your hair, the more your hair weakens. Your hair shafts become weak which results in hair loss. The hair loss may be temporary at the beginning but if the hair is not treated properly, it can lead to permanent hair loss.

Once you rinse off the dye from hair the cuticle comes back but it’s later now as your hair already is damaged.

Please note that your hair is not going to react well to the chemicals in the hair dyes, as they may dry out. The dried hair will result in damaged hair roots, which will result in hair loss.

Apart from that, the continuous combing and washing of hair will lead to weaken them. You will lose a lot of hair during this stretching and combing of hair.

A brief overview of the hair’s structure :

the human hair structure explained

Your hair is a part of your personality, you should thus treat them with extreme care and follow a proper hair care routine.

The outer layer cuticle is the protective layer of hair, the cortex provides moisture and texture to the hair and the medulla is the innermost layer, it might be absent in light hair (blonde hair).

Do temporary and permanent hair dyes cause hair loss ?

There are two types of hair dyes, temporary and permanent hair dyes. The question is does both cause hair loss and damage your hair ?

Temporary Hair Dyes :

Temporary hair dyes are also known as semi-permanent hair dyes. These will give your hair natural looks. The colours will not lighten the shade of your natural hair, as these do not contain any bleaching agents in it.

The effect of these dyes will last up to 6 weeks maximum and after that, the color on hair will start to fade away. These dyes do wash away, which means the temporary dyes need to be reapplied after 2 months.

However, those hair dye don’t cause hair loss, as they are less damaging. However frequently applying these dyes without giving your hair a break can lead to alopecia at a minor level.

Permanent Hair Dyes :

Permanent hair dyes are far more damaging than the semi-permanent ones. These dyes use ammonia and hydrogen peroxide to lift the color of your hair. Furthermore the peroxide contained within these dyes damages the hair shafts and breaks the keratin structure.  

If your hair is naturally dark in color and you bleach them to make them blond, then your hair will experience severe kind of damage that might be irreparable.

The hair will become weak and they will break which will result in alopecia, the hair loss might be temporary but it will take time for the hair to regrow.

Baldness issues that occurs due to hair breakage are only temporary. But if these chemicals infused dyes touch the roots of your hair then you might lose them.

The frequent use of permanent or temporary hair dyes will result in hair thinning and frequent hair loss.
