In the world of haircare, frizz is a familiar challenge for both professionals and anyone struggling with unruly, dry, or porous hair. After washing, in humid conditions, or due to improper care, hair may start sticking out in all directions, losing its smoothness and shine and appearing untidy. Before exploring solutions, it's essential to understand what causes frizz and how keratin treatments can help combat it.

Why Hair Gets Frizzy: Causes of Frizz

Frizz occurs due to changes in the hair’s structure. Normally, the cuticle (the outer layer of the hair shaft) lies flat, creating a smooth surface. But when this layer is raised, the hair absorbs moisture from the air, becoming porous, fragile, and difficult to manage.

Main causes of frizz include:

  • Cuticle damage – often caused by frequent coloring, bleaching, or excessive heat styling (straighteners, curling irons, blow dryers).
  • Lack of moisture – dry hair absorbs ambient humidity, which leads to frizz.
  • Porous hair – this can be genetically determined, especially common in curly or wavy hair, or acquired through improper care.
  • Inappropriate products – using harsh shampoos or products not suitable for your hair type, along with insufficient hydration and nourishment, can exacerbate the issue.

The key to fighting frizz is restoring hair structure, reducing porosity, and sealing the cuticle. One of the most effective methods is keratin treatment.

How Does Keratin Treatment Work?

Keratin is a protein and the main building block of hair. Chemical or mechanical damage can deplete keratin in the hair, making it lose its smoothness, shine, elasticity, and shape. Keratin treatment is a professional procedure that fills structural gaps with hydrolyzed keratin and locks in the result using heat.

The mechanism behind keratin treatments involves several steps:

  • Penetrating the cortex – small protein molecules fill in micro-damage in the hair shaft.
  • Smoothing the cuticle – hair becomes smooth as the cuticle scales align tightly again, creating a shiny surface.
  • Protective barrier – the treatment forms a coating that shields the hair from moisture, UV rays, dust, and other environmental stressors.

The result is significantly reduced frizz, enhanced shine and elasticity, and easier maintenance. Keratin treatment also straightens the hair, eliminating waves or curls. It is especially beneficial for those who deal with frizz every time they wash their hair.

What to Know Before Getting a Keratin Treatment

Keratin treatments are in-salon procedures that require knowledge of chemistry, hair types, and application techniques. Contrary to popular belief, they’re not just for straightening curls — they also repair and provide anti-frizz benefits for wavy or even straight but damaged hair.

Consider the following before undergoing the treatment:

  • Product formulation – While many brands advertise formaldehyde-free keratin, most keratin treatments still contain formaldehyde or its derivatives, which are responsible for the smoothing effect. Modern formulas are safer but must be applied strictly according to instructions.
  • Hair condition – Severely damaged hair may need preparatory treatments (such as hair botox or reconstruction) to ensure long-lasting results.
  • Post-treatment care – Use gentle (preferably sulfate-free) shampoos, avoid salt and harsh chemicals.

With proper care, results can last from 2 to 5 months, depending on the product, hair structure, and maintenance routine.

Top 3 Keratin Treatments for Managing Frizz

The market offers a wide range of keratin treatments varying in composition and intensity. One of the most advanced brands is Beneliss, created by a renowned Brazilian manufacturer. Here are the top three options for frizz control:

  • Beneliss Max Power – The strongest formula in the Beneliss lineup, designed for very curly, thick, and coarse hair. Enriched with macadamia oil, vitamins, and fatty acids, it deeply nourishes and restores damaged hair. It also creates a protective layer that shields hair from environmental damage. The result is smooth, silky, and healthy-looking hair.
  • Beneliss Coffee Force – Ideal for Afro-textured, tight curls, and dense natural hair. This treatment creates a thick, shiny protective layer while strengthening the hair with amino acids and coffee extract. It improves elasticity, reduces breakage, and acts as a heat protectant.
  • Beneliss Beneplastia – A medium-strength formula suitable for color-treated, lightened, or Slavic hair types with slight waves. It fills in gaps in the hair structure, eliminates frizz, and adds shine and smoothness. Ideal for restoring softness and hydration to damaged strands.

Post-Keratin Hair Care: Maintaining the Results

Keratin treatment is just the first step toward beautiful hair. Long-term results require proper at-home care. Without it, your hair may quickly revert to its previous condition.

Essential post-treatment care includes:

  • Sulfate- and paraben-free shampoo – gentle cleansing that doesn't strip keratin. If you have an oily scalp, you may need a balancing shampoo but should protect the hair length by pre-applying conditioner or limiting shampoo to the roots.
  • Keratin- or ceramide-infused conditioner – helps close the cuticle and maintain structure. Use it every time you wash your hair.
  • Heat protectant before styling – although the hair already has a protective layer, heat protectants preserve shine and elasticity.
  • Masks once or twice a week – for extra hydration and nourishment.

Also avoid saltwater, frequent coloring, and using high-heat tools without temperature control.

Are There Alternatives?

Keratin isn’t the only way to fight frizz. Alternatives like hair botox, nanoplasty, and lamination offer different mechanisms. However, keratin remains the most effective because it works at the structural level, not just cosmetically.

Frizz is not a curse — it's a sign that your hair lacks moisture, keratin, and proper care. Salon keratin treatments offer a reliable solution, bringing back shine, smoothness, and vitality. But remember: lasting results depend not only on your stylist but also on your daily routine. Choose quality treatments, maintain your hair properly, and frizz will become a thing of the past — not a daily struggle.
