Does keratin cause hair loss?

Keratin is a fibrous protein forming the main structural constituent of hair skin and nail, it is a protective protein. The protein is also used as an ingredient in hair products. According to some keratin products can help your hair become healthier, smoother etc. The natural keratin present in our hair can be diminished due to overuse products, chemical treatments and heat styling. It is when this happens that many people use keratin shampoos and treatments. The keratin in cosmetic products are taken from animal parts such as hair, feathers etc. So people who prefer vegan products tend to not use it.

Keratin treatment or Brazilian Blowout, is a cosmetic treatment that helps smoothen out your hair Some even use keratin treatment as an umbrella term for all types of hair smoothening.


Keratin shampoo is one of the most popular forms of keratin treatment used by people, the shampoos claim to improve the appearance and texture of the hair while simultaneously reducing frizz and breakage. So how does keratin shampoo work, just like how natural keratin forms a barrier in a hair shaft, the shampoo works by creating a barrier on the hair. This coating will protect the hair from further damage while smoothing it out and making it appear healthy.


Keratin salon treatment is done in a salon by a professional hair stylist, and gives more intense results compared to the shampoos because the process involved in salon keratin treatment is also more intense.


Despite this and the popularity of keratin products, the protein also has some major flaws (i.e. side effects). Not many people know about the side effects of keratin products, mainly because the probability of the bad effects happening is not confirmed. But it is a known fact that Keratin treatment products contain formaldehyde (according to a study conducted in the year 2012 it was found that6 out of 7 keratin treatment product contains 0.96 to 1.4 percent of Formaldehyde), which is considered to be carcinogen by the American Cancer Society. Formaldehyde is a strong smelling, colorless gas. Other than cancer it also has many other side-effects such scratchy eyes, a sore throat, and nose bleeds.

 The question is does keratin cause hair loss?

Keratin at salon and at-home treatments both causes hair damage and loss because of the harsh chemicals including formaldehyde. So it is wrong to say keratin causes hair loss but instead, it is the chemicals in the keratin treatment products and shampoos that may cause hair fall.

How to stop hair loss due to Keratin?


  • Massage: Use an oil that promotes hair growth like castor or coconut oil and massage it into your scalp. This will increase blood circulation to the scalp and the properties of the oil will help in the healthy growth of your hair 


  • Avoid brushing wet hair: It is easier to lose strands of hair when you brush your hair while it is wet. This is because wet hair is weak.
  • Use gentle or mild shampoos and conditioners: You already let your hair go through chemicals it doesn’t need anymore. Also, the Keratin barrier may get destroyed if you use products with harsh chemicals.


  • Moisturize: Use nourishing products that lock in the moisture in your hair or help add more moisture to your hair.


  • Enrich your diet with protein and also try to take biotin supplements for the better health of your hair.


  • Drink water and stay hydrated, drink at least eight cups of water a day.


  • Green tea: Brew two bags of green tea in one cup of water and cool it. Apply it to your hair and wait for about an hour and wash it off with water.
