What is Keratin?

chemical structure of human keratin
Keratin is a fibrous structural protein found in the hair, skin, and nails of the human body. This protein is arranged in a helical shape, allowing for flexibility and movement. Up to 90% of hair is composed of it. Because it can bend and move freely, it gives hair an elasticated property.

Although it’s less prone to damage than other types of proteins, its outer layer can be compromised. When the surface of a hair cuticle is weakened, it can affect the underlying proteins as well. This leads to dull, dry hair.

What’s a good, effective keratin treatment for hair?

Keratin is good for smoothing down the cells that overlap each other to form your hair strands. The end results depend on the kind of treatment you use and your hair type, but generally, the hair becomes glossy and easier to style.

These hair treatments use keratin that’s derived from natural sources such as the feathers, horns, or wool from other animals. It’s applied to the hair with the purpose of filling in any holes on the outside of the cuticle caused by damage. The extracted protein is then added into the following products:

1. Keratin shampoo

This shampoo formula gently coats the hairs with a keratin solution that’s suitable for frequent use. It works by nourishing the hair with every wash to smooth the hair strands and create sleek hair every day.

Dr. Balwi recommends using a hair shampoo that’s enriched with keratin as a way to combat hair loss. When used regularly, the formula helps to strengthen the hair strands and improve the general condition of the hair.

2. An intensive hair treatment

The end result of this intensive treatment depends on the kind of formula that you use and your hair type. Some treatments are more intensive than others depending on the different ingredients included within the product.

With an intensive keratin hair treatment, you can expect the results to last for 4-6 months. Long-lasting, intensive hair treatments like this should be performed in a hair salon to ensure that there’s no overprocessing that can cause damage. The chemicals within these treatments can be harsh to the hair if not used correctly.

3. Diet supplements

Taking keratin in the form of a dietary supplement supplies the hair follicles with the protein needed for healthy hair growth. A supplement will not have the same effect of repairing present hair cuticles, but it will promote the growth of strong, shiny hair.

The product that will work best for you depends on your hair type and your hair concerns. Sometimes, a combination of the products can be used to maximise the benefit.

How does keratin repair damaged hair?

how does keratin repair damaged hairKeratin serves as an impermeable protective barrier for hair cuticles. When hair is damaged, the cuticle becomes porous, allowing moisture to enter. The strand then swells, resulting in fragile, dull, or dry hair. A treatment or shampoo containing this protein repairs damaged hair by restoring the protective barrier which also prevents further damage.

Can keratin help to grow hair?

While keratin does not inherently cause hair to grow faster than its normal rate, it can prevent breakage which protects the hair that’s already present. Therefore, it helps to maintain a thick head of hair to combat hair loss.

A study has demonstrated that a soluble form of keratin, Cynatine HNS, can lead to a significant increase in hair shine, growth, thickness, and strength. The largest impact on hair growth is the improvement of hair health.

If you are experiencing hair loss due to androgenic alopecia, telogen effluvium, or other reasons, using a shampoo with keratin can help to slow down the hair loss process. It cannot entirely reverse the effects of hair loss, but it can be beneficial for preventing further damage or breakage.

What are the side effects of keratin treatments?

If you choose to apply it directly to hair through a treatment process, it is important to recognize the potential risks that could occur. Some treatments can include the chemical formaldehyde, which is a potential carcinogen. In addition, formaldehyde exposure can also lead to irritation of the eyes, ears, nose, and throat. So, make sure you know the ingredients before applying this to your hair.

When taken in supplement form, keratin can exhibit many of the same benefits of a topical treatment. It can lead to stronger, shinier, thicker hair. However, overconsumption can have harmful impacts on the body. If you take too much keratin, it could lead to kidney damage. Therefore, be careful to take only the recommended dose of this oral supplement.

Is a keratin treatment good for thin hair?

Despite the many perks of intensive treatments, not everyone is an ideal candidate. If your hair is naturally thin or you are experiencing substantial hair thinning, a keratin treatment could cause more harm than good.

This type of chemical treatment could be too harsh for thinner hair or weigh it down, drawing attention to the already thin condition. However, a keratin supplement or shampoo may be able to provide the benefits of this treatment without the negative effects.

Can hair grow back after it started thinning?

can hair grow back after it started thinningOften, hair can grow back after it has started to thin. The best approach to addressing thinning hair is to establish the cause, and then find the solution. If you suffer from androgenic alopecia, or pattern baldness, the hormone that provokes follicle miniaturisation, eventually causing hair loss, should be treated.

If you are instead faced with telogen effluvium, or stress-induced hair loss, your solution lies in making changes in your personal life to reduce stress etc. If a hair follicle is dead and the skin has scarred, it cannot regrow hair. But if the skin hasn’t scarred there’s the potential to restore the growth of strong, thick strands of hair.

Have a proper nutrient intake to increase your hair’s health

In addition to treating the cause of your hair loss, it is also beneficial to provide your hair with the nutrients it needs. If you are wanting to make your hair grow back faster and thicker, focus on your diet and hair care routine. Be sure to consume vitamins and minerals that sustain healthy follicles. These include the following:

  • Vitamins A, B, C, and E
  • Iron
  • Zinc

Providing your body with the nutrients it needs allows for more successful hair growth results. Furthermore, preventing damage through an appropriate hair care routine can also maintain a healthy head of hair. Reduce the use of hot styling tools, chemical treatments, and tying up your hair. This will avoid drying out your hair and breakage.


There are many products on the market that can help treat damaged or thinning hair. A great option is keratin-rich formulas that come in the form of hair treatments, shampoos, or dietary supplements.

Keratin is a structural protein that comprises up to 90% of hair. It creates a protective barrier, and if this is damaged, can allow water to enter and cause swelling. The purpose of a keratin treatment is to restore any gaps in the hair cuticle, restoring strength, shine, and flexibility.

Keratin consumed through an oral supplement will provide the body with the nutrients it needs to maintain healthy follicles. In addition to keratin, a well-balanced diet and a hair care routine that prevents damage can foster healthy hair. With the proper care, a thicker, stronger, shinier mane can be restored.
