Can dyeing cause hair loss? Mystery solved



During the peak of the pandemic, hair dyeing turned out to be a popular pastime. Some people did it as a style assertion and others just to have some fun with different colours. I am positive you too, took advantage of the free time on hand to colour your hair or cover up your greys.

One element I did note myself after weeks of colouring, was a significant amount of hair loss found around the bathtub, washbasin, and even on my comb.

Did you note this around your house? Can dyeing your hair cause hair loss?

Let’s be very sure that the hair dye is the cause, if not, there are other possible causes to consider.

Is it ‘lost hair’ or ‘broken hair’? Let’s be clear.

When you brush or comb your hair, you do discover some of your hair attached to the brush. Other evidence you will normally find would be around the washbasin or shower areas. Do you think this is lost or damaged hair?

“Lost’’ hair will have a bulb attached at the end of the hair. While “damaged’ hair does not have a bulb. That is the primary difference.

If “broken’’ hair is what you established as the evidence, then you must treat your hair gentler. In other words, you got to be kinder to your hair!

Here are a few beneficial recommendations that will help you deal with your hair better:

  • Don’t use plastic or metallic brushes.
  • Use warm and not hot water when shampooing.                         
  • Use only mild shampoos.
  • Avoid the use of chemical dyes.
  • Reduce the warmth while drying your hair.

If you find a little hair in the shower drain or your brush/comb, there is nothing to be concerned about. Most human beings shed an average of 50 – 100 strands per day, which will be replaced in the normal natural cycle anyway.

Let’s now look at how hair dyes can be the cause of your hair falling out.

How do hair dyes cause your hair to fall out?

Hair dyes include ammonia, hydrogen peroxide, and lots of different other chemicals that potentially can result in hair loss.

These chemicals can penetrate your hair and harm its outer layer, making them breakable. They also can damage your hair structure, giving you frizzy and dry hair.

But how do hair dyes cause your hair to fall out in the first place? The predominant culprits are bleaching agents and other poisonous chemicals substances.

It also depends on how frequently you dye your hair as well. These are a number of reasons that can cause your hair to fall.

Let’s check out the individual chemicals to understand a little more. The cuticle is the outer layer of the hair, it is like the bark of a tree. It protects the hair from damage. The Ammonia in dyes penetrates the cuticle to elevate the pH level of the hair.

This damages the cuticle and might result in hair loss. For these reasons, many manufacturers in recent times, claimed now no longer have Ammonia in their hair products.

The Hydrogen Peroxide in dyes is used to provide you the preferred colour. It remains in your hair until it penetrates the hair shaft.

This leaves your hair dry and frizzy making it venerable and easy to break. The longer Ammonia and Hydrogen Peroxide stays in your hair, the weaker your hair shaft becomes, resulting in your hair falling off.

Hair loss can be temporarily, however, if it isn’t treated early, it may lead to permanent hair loss.

Your hair isn’t designed to handle harsh chemicals and the added pressure of continuous combing, washing, and dyeing will subsequently weaken your hair.

Do both temporary and permanent hair dyes cause hair loss?

Temporary and permanent hair dyes are the 2 predominantly categories of hair dyes in the market. The common question people ask me is always whether both hair dyes cause hair loss?

Temporary or semi-permanent hair dyes do not include any bleaching agent. This means it will not lighten the shade of your hair colour.

Hair dyes last a maximum of six weeks after which the colour will fade away after many washes. You need to apply again if you want to retain the same colour.

Even though it does less damage to your hair, frequently applying these dyes without a break will lead to alopecia at a minor level. (Alopecia is a condition that causes people to lose hair from a single area or multiple areas)

Permanent dyes with Ammonia and Hydrogen Peroxide are more damaging as explained earlier. The frequent use of permanent or temporary hair dyes certainly affects hair thinning resulting in hair loss.

If your investigation is not conclusive that hair dye is the main cause then you have to consider the following possibilities.

Natural cycles – your hair grows in cycles. Old hair falls out while the new one replaces it. Your hair will go through three cycles of growth phases. The growth phase can last up to six years.

Heredity if someone in your family is suffering from hair loss, there is a good chance this can happen to you. You just can’t fight genetics. The reality is that you will suffer hair loss no matter what.

Stress – unfortunately, stress can cause hair loss. Your entire body system is regulated by hormones. Stress can alter the normal interaction of hormones cause you to lose your hair. For a more in-depth explanation check out the Mayo Clinic article on hair loss.

Medical condition – if you experience an unusual amount of hair loss, there is a strong possibility that your medication is causing you some side effect. I would advise you to see your doctor because sometimes switching drugs may help.                                                                 

Natural products that can help your hair to grow.

There are many natural hair growth products available to help you have healthier and fuller hair. Ingredients such as castor oil, caffeine, rosemary oil, and biotin help promote healthier and stronger hair. Caffeine compounds stimulate the hair follicles to speed up hair growth.
