What Does Keratin Do for Hair? Strengthen and Protect!

Hair is one of our most prized possessions, and it is a great source of pride when it is healthy and strong. We use various hair care products to maintain the health of our hair, but have you ever heard of keratin and its benefits? In this article, we will discuss how keratin can improve the health and appearance of your hair. So, let’s get started.

What is Keratin?

Keratin is a fibrous protein that is the primary component of hair, nails, and skin in mammals. It is a tough, insoluble protein that protects and strengthens the hair. Keratin is produced by cells called keratinocytes, which are found in the outer layer of the skin, the nails, and the hair follicles.

How Does Keratin Strengthen Hair?

Keratin is an essential protein that plays a crucial role in the strength and structure of hair. It acts as a building block for the hair, and it makes up more than 90% of the hair’s composition. When the hair is exposed to heat, chemicals or the sun, the keratin protein in the hair breaks down. The result is hair that is brittle and prone to split ends. Keratin treatments and hair products that contain keratin can help to restore the health of your hair by increasing the protein content in your hair.

Keratin Treatments

Keratin treatments are a popular solution for those who want to improve the texture and appearance of their hair. The treatment involves applying a keratin formula to the hair, which then gets sealed with heat. This process allows the keratin to penetrate the hair shaft, creating a protective layer around the hair. This protective layer helps to prevent damage from heat, chemicals, and other environmental factors, making the hair stronger and less prone to breakage. Keratin treatments are suitable for all hair types, including curly, frizzy, and relaxed hair.

Keratin Hair Products

Keratin is not only available in treatments but also in various haircare products such as shampoos, conditioners, and hair masks. These products contain keratin as one of their active ingredients and help to reinforce the hair, making it stronger and more resilient. They also help to eliminate frizz and reduce breakage. Keratin hair products are an excellent option for those who want to maintain the effects of a keratin treatment or for those who want to improve the strength and appearance of their hair.

How Does Keratin Protect Hair?

Keratin not only strengthens the hair, but it also protects it from environmental factors that could cause damage. The hair is constantly exposed to external factors such as pollution, UV radiation, and humidity, which can have adverse effects on the hair. These factors can cause hair to become dry, weak, and prone to breakage. Keratin helps to protect the hair from these factors by creating a barrier on the hair’s surface. The barrier helps to lock in moisture, which is essential for healthy hair.

Keratin and UV Radiation

UV radiation from the sun can cause hair to become dry and brittle, leading to breakage. UV rays can penetrate the hair cuticle, leading to damage at the molecular level. Keratin can help to protect the hair from UV radiation by creating a barrier on the hair’s surface, preventing UV rays from penetrating the hair cuticle. Additionally, some keratin hair products contain UV filters, which provide additional protection from harmful UV rays.

Keratin and Pollution

Pollution is another environmental factor that can adversely affect the hair. Pollution can cause hair to become dull, lifeless, and prone to breakage. Keratin can help to protect the hair from pollution by creating a barrier on the hair’s surface, preventing pollutants from adhering to the hair. Additionally, some hair products that contain keratin also contain ingredients that help to remove pollutants from the hair.

The Benefits of Keratin for Hair

There are several benefits of keratin for hair, and these include:

  • Strengthening hair
  • Reducing breakage
  • Eliminating frizz
  • Improving hair texture and appearance
  • Protecting hair from environmental factors

How to Maintain Keratin-Treated Hair?

A keratin treatment can help to improve the health and appearance of your hair, but it is essential to maintain the results of the treatment. Caring for keratin-treated hair involves gentle handling of the hair and avoiding products that could strip the hair of its natural oils.

Gentle Handling

Gentle handling of the hair is essential when caring for keratin-treated hair. Rough handling of the hair could cause breakage, leading to split ends. Avoid pulling or tugging on the hair when brushing or combing. Instead, use a wide-toothed comb and start at the ends of the hair, working your way up to the roots.

Use Sulfate-Free Products

Use sulfate-free products when caring for keratin-treated hair. Sulfates are found in many shampoos and can strip the hair of its natural oils, leading to dryness and breakage. Using a sulfate-free shampoo and conditioner will help to maintain the moisture balance in your hair, leaving it soft and supple.

Avoid Heat Styling

Avoid heat styling your hair frequently. Heat can cause the keratin in your hair to break down, leading to damage and breakage. If you must use heat styling tools, use a heat protectant spray to minimize damage.

Regular Maintenance

Maintaining keratin-treated hair requires regular visits to the salon for touch-ups. The frequency of touch-ups will depend on the type of keratin treatment you received and your hair’s texture. Your stylist will advise you on how often you need touch-ups.

Conclusion

Keratin is an essential protein that is crucial for healthy hair. It strengthens the hair, improves its appearance, and protects it from environmental factors that could cause damage. Keratin treatments and hair products that contain keratin are excellent options for those who want to improve the health and appearance of their hair. Maintaining keratin-treated hair requires gentle handling, avoiding sulfates, and minimizing heat styling. With proper care, your hair will remain healthy and strong.
