Keratin hair treatments

Keratin treatments help repair and moisturize hair. They revitalize and strengthen it, protecting it from external factors like the sun, dust, or smoke, which can make hair frizzy and dull. Additionally, using a keratin hair treatment will help protect it from the heat of hair dryers and straighteners.

Keratin is a protein naturally present in hair fibers, making up 80% of each strand. It directly affects the appearance of hair, from strength and shine to vitality and volume.

For this reason, when hair loses keratin, it appears lifeless. The hair cuticle opens and the hair expands in search of moisture in the environment, creating frizz.

There are a wide variety of keratin treatments that also include other ingredients based on the needs of each hair.

What does a keratin treatment consist of and which one should you choose?

Keratin treatments help regenerate the hair cuticle and enhance its protection, hydration, shine, and vitality. Currently, there are several nourishing and effective keratin treatments available for hair, tailored to your needs and intended for daily use.

Keratin treatments come in a variety of formats, from keratin serums, restructuring fluids, leave-in treatments, to concentrated masks and professional treatments. Their effects aren't necessarily the same and also depend on the formulation and ingredients.

Keratin serum

Keratin serum is a concentrated product designed to be applied directly to the hair fiber. Unlike a product that needs to be rinsed out immediately, the serum can remain on the hair longer, allowing the conditioning ingredients to form a film on the surface.

Therefore, not all keratin serums are the same. Molecular size influences how the ingredient interacts with the hair. The benefits of keratin serums are numerous:

• Shine: by acting on the surface of the hair, they leave a more uniform appearance that allows light to reflect more regularly, making the hair appear shinier.
• Softness : the fiber can be more pleasant to the touch thanks to the combination of proteins, conditioning substances and film-forming agents.
• Combability : The treatment can reduce friction and tangling, making combing easier.
• Frizz Control: Forming a film on the fiber can help reduce frizz and sensitivity to humidity.
• Reduced breakage : It gives a firmer appearance and some formulations containing keratin peptides have shown an improvement in the mechanical properties of the fibre.

Many keratin serums are combined with heat protectants to further protect the hair from heat and external agents.
