What Is Keratin Treatment? A Complete Guide to Smooth, Frizz-Free Hair

Do you dream of smooth, frizz-free hair that stays sleek for weeks? If so, a keratin treatment might be the perfect solution. You may have heard about it from your hairstylist or wondered how supermodels achieve such straight, shiny hair. Well, you're in the right place!

In this article, we’ll explore what is keratin treatment, how it works, its benefits and risks, and how to maintain the results.

A keratin treatment is a professional hair-smoothing procedure designed to reduce frizz, enhance shine, and make hair more manageable. It infuses keratin—a natural protein found in hair—into the cuticle to repair damage and create a sleek, polished look. If you're looking for the best hair treatment for smooth hair, keratin treatments are among the top solutions.

Keratin treatments are ideal for those struggling with frizz or unmanageable hair. They help smooth and soften the hair for several weeks without permanently altering its natural texture, making styling easier while maintaining a sleek, polished appearance.

The Science Behind What Is Keratin Treatment

Before diving into how keratin treatments work, let’s first understand the structure of human hair. Hair consists of three layers:

  • Medulla – The innermost core (mostly present in thick hair).
  • Cortex – The thick middle layer, which determines strength, elasticity, and color.
  • Cuticle – The thin, protective outer layer that shields the inner structures.

Keratin treatments primarily target the cortex, infusing keratin into the hair structure to smooth and strengthen it. This process changes how hair reacts to humidity, significantly reducing frizz.

Inside the cortex, keratin exists as long spiral-shaped protein chains, held together by chemical bonds such as ionic, disulfide, and hydrogen bonds. Additionally, weaker forces known as van der Waals forces help maintain the alpha-helical structure of keratin. Groups of these helices form filaments, which make up the bulk of the hair's structure.

Keratin treatments modify these protein strands, temporarily altering their structure to transform hair texture and appearance. As keratin penetrates the hair, it interacts with these bonds, adjusting the hair’s smoothness and manageability based on its thickness and length.

The Keratin Treatment Process

The keratin treatment process may take 3 to 6 hours in general, and if you are with a professional, it will not be a problem. Let's review the whole process step by step.

  1. Double Shampoo – Your stylist will first apply a double shampoo to your hair to remove all dirt, oil, and other products.
  2. Blow Dry – After washing your hair, your stylist will blow-dry it. It could take longer if you have thick, heavy hair. The stylist will continue drying until your hair is 80% dry.
  3. Apply Keratin and Wait – After drying, the stylist will apply keratin with gloved hands and wait for at least 15 minutes.
  4. Blow Dry Again – The fourth step is blow-drying your hair again while the solution is still in it. This can be difficult due to the thick consistency of the product.
  5. Flat Iron – In the next step, your stylist will use a flat iron to straighten the hair. Starting at the nape of the neck, they'll take sections about two to three inches wide and iron them several times. This process is the most important and can take 2 to 3 hours.
  6. Shampoo and Final Blow Dry – After the solution is dry, your stylist will wash it out with shampoo, followed by a sealant and a final blow-dry to reveal smooth, shiny hair.

Benefits of Keratin Treatment

Keratin treatments provide multiple benefits:

  • Frizz Control & Smoothness – Reduces frizz and makes hair more manageable.

  • Easier Styling – Cuts down styling time significantly.

How Long Does a Keratin Treatment Last?

After spending 5 to 6 hours and a hefty amount on this process, you must be wondering how long it will last. Generally, a keratin treatment for hair lasts between 12 and 30 weeks, depending on your hair type and aftercare.

Using a sulfate-free shampoo and limiting hair washes can help extend its lifespan.

Cost & Aftercare Tips

How much does a keratin treatment cost, and what maintenance is required?

Treatment Costs – The price of a keratin treatment varies widely depending on the product, location, and hair length, ranging from $100 to $450 per session.

Aftercare Requirements – You might be wondering, how long will it last? Well, the results typically last between 12 and 30 weeks. Why such variation? Because, like everything else, our hair requires proper care, maintenance, and treatment to retain the effects of a keratin treatment.

Safety and Health Considerations

Keratin treatments smooth hair, but some contain chemicals like formaldehyde, which can cause irritation, especially in enclosed spaces. While they provide long-lasting results, excessive exposure may be uncomfortable.

Choosing a low-formaldehyde or formaldehyde-free keratin treatment can reduce potential risks while still delivering excellent results. Proper ventilation during application and limiting the frequency of treatments can help maintain healthy hair.

If you're pregnant or have health concerns, it's best to consult a professional first to ensure a keratin treatment is safe for you.
