If your hair is thin, you might be looking for an exclusive way to maintain the hair, whether you naturally have fewer hair strands or have lost some hair.

There are numerous special hair routines that are useful for treating different categories of hair and their related problems. Keratin treatments are one of these. The Keratin treatment can also be called the Brazilian blowout. When administered, the Keratin hair routine can minimize hair frizz, improve the color of the hair, and tame or straighten curly hair to make it look healthier and shinier.

Product manufacturers and hairstylists generally advise clients to use keratin hair treatments for people with curly, frizzy, thick, or coarse hair. People with curly or coarse thin hair might want to consider using the Keratin treatment. People with straight or fine thin hair might not need keratin treatments if they seek the best style.

You should know that keratin treatments might be toxic to the client or lead to various health problems; this treatment should be done cautiously.


Do you need to use keratin treatment to improve thin hair?

A protein by nature, Keratin exists naturally in the body of humans. We have Keratin in our hair, skin, and nails. Keratin is present in our hair, making it healthy and strong, while routine chemical treatments such as bleaching and colouring could compromise hair strand integrity.

The Keratin routine for the improvement of hair usually includes additional Keratin obtained from products of animals such as chicken feathers and wool. This is used to make the hair look smoother and healthier.

There are various researches that have supported Keratin as a hair treatment routine for the achievement of healthier strands:

In 2018, reliable research from the International Cosmetic Science Journal revealed that more keratin particles made the hair smooth and improved the strength of the hair by 40 percent.

A different study in 2018 from Biotechnology-based reports discovered that the application of K31 protein increased the diameter of the hair that was damaged by 49 percent. The diameter of the hair that was bleached was increased twice. The research also found that the keratin treatment, which lasted for one hour, made curly hair straight.

We usually recommend using keratin hair routines for hair that is: either bleached or coloured, thick, coarse, or frizzy.


First, discover the type of hair that you have.

You will need to know what type of hair you have before getting a keratin hair treatment. Since “thin” in this case can be used to describe various things:

The density of your hair follicles means that there are fewer hair strands in your head than in other places. This means that people whose hair is either medium or thick have an increased number of hair strands.

The real hair thickness on each of your hair: Most of the time, hair with a thinner diameter is called “fine” hair. This is confusing as the opposite hair type could be called coarse or thick.

This means that the fine or thin hair would be a lot stronger than the coarse or thick hair.

The thin hair determined by the amount of hair on the head can be in various hair textures. People might choose to use keratin treatment if their thin hair is coarse, color-treated, or curly. The thin hair which is straight and fine may not get a benefit from keratin hair routines.

People could be looking to give their hair more volume if their hair is thin or thinning down. This means that they might need to go for more effective hair treatment routines than Keratin.


Does the keratin thin hair treatment cause any risks?

Before getting a keratin hair treatment at home or in the salon, discuss with your hairstylist or understand the information on the product package and read up on all the online reviews on the product.

There are useful websites such as that of the Environmental Working Group for finding certain ingredients and products to ensure their safe consumption.

Just know that many companies label keratin hair routines as safe because keratins are naturally derived from animals and humans.

Then again, keratin routines also make use of hazardous chemicals such as formaldehyde. A risky chemical, formaldehyde, is known to be a toxic chemical. Many hair treatments with Keratin come with harmful amounts of this chemical that are not within the safe levels as fixed by the governing boards of cosmetic products.

Then again, it is disturbing that these products barely name formaldehyde as among the ingredient since the product makers rename the chemical once it gets mixed with elements such as water. Excess formaldehyde might prove too dangerous for the clients and the stylists that often use these products.

The keratin hair routine might also cause skin irritation and lead to different other physical reactions. Several supplements that come with excess Keratin are unregulated by the FDA, such as prescription and over-the-counter medications.

A study done in 2020 revealed that a reliable source from the Journal of Cosmetic Dermatology emphasized the dangers of contacting swelling and dermatitis from Keratin hair treatment procedures among people whose skins are sensitive. One likely reason for this is the presence of formaldehyde in the skin or different other ingredients.


More side effects noticed when keratin hair treatments are:

  • A burning feeling in the nose, mouth, and eye
  • A strong smell when being applied.


 How is keratin thin hair treatment done?

Keratin can be added to the hair in numerous ways. You can decide to visit a hairstylist to get your keratin hair treatment in the salon. These hair treatments might last for some hours and usually involves heat application for the setting of the keratin hair treatment.

We have different other keratin products sold over-the-counter that can be applied to the hair. You should closely stick to the given directions and check all reviews before buying and applying these products.


What is the duration of the keratin thin hair treatment?

Expertly administered keratin thin hair treatments could stay for about six months, and this depends on how you treat the hair after the first treatment. These treatments could last for a much shorter time if the hair is frequently washed with water or styled regularly using heat.


What other health tips for thin air are there?

We have many other ways of ensuring that the thin hair you have to keep on looking healthy and for treating thinning hair:

Consume a healthy balanced diet that contains a lot of fruits, dairy, vegetables, protein, whole grains, and healthy fats for the essential vitamins to make the hair strong and healthy.

The takeaway

It is debatable whether a keratin hair treatment can be used to improve thin hair. You could use keratin hair treatments if you have a thin hair density and if your hair is coarse, frizzy, curly, or damaged from bleach or color. A straight and fine hair may not necessarily need to undergo any keratin routine and any other useful volumizing techniques.

Before going for this option, you should check out how safe the keratine routine is before you get it or before you use keratin-based products. It can also be useful if you keep a healthy eating diet while looking for different options to handle hair thinning conditions.
