Professional keratin treatments, known as Brazilian straightening, use high heat and potent chemicals to deliver an extremely smooth result, but these intensive procedures are not suitable for those seeking a permanent solution for hair health. In contrast to salon treatments, at-home keratin-enriched hair care products focus on the benefits of the active ingredient, offering a gentler alternative that does not compromise the integrity of hair strands. Keratin is not new to the beauty market, but specialists' observations indicate a significant increase in the popularity of products containing this strengthening ingredient, with its benefits recognized for improving hair quality.

Specialist Elena Lavagni, owner and founder of Neville Hair & Beauty, explains that keratin is a fibrous structural protein that constitutes a major component in the composition of various human body tissues, including skin, hair, and nails. Previously considered an ingredient exclusive to hair salons, keratin has become the subject of broader discussions regarding its mechanism of action, details now explained by industry experts. According to Elena Lavagni, keratin is abundant in the outer layer of the skin (epidermis), where its primary role is to provide structural strength and protection to the body. [1]
For individuals dealing with fragile hair and breakage, keratin helps repair and strengthen the hair shaft, reducing loss and improving overall health, being particularly effective in smoothing the cuticle for more manageable hair. Keratin treatments are beneficial for hair damaged by chemical procedures such as coloring or perming, thermal stress caused by flat irons or curling wands, as well as environmental factors like sun exposure and pollution.

The ingredient not only corrects visible damage but also facilitates achieving a glass-like texture; it helps soften coarse or rough strands and adds volume and thickness to fine strands by reinforcing the structure, although lightweight formulations are recommended to avoid weighing the hair down.

The profile market offers a diverse selection of products tested and approved by Stylist magazine's beauty team, demonstrating that salon results can be achieved without prohibitive financial investment. A shampoo appreciated by the Stylist team integrates a smoothing complex with 4% keratin, combined with argan oil, to soften the cuticle, reduce tangles from the first wash, and leave hair shiny and soft. The restorative Gisou serum, known for its honey-rich formula, now integrates plant-origin keratin to seal split ends and strengthen flyaways, functioning simultaneously as an effective thermal protectant up to 230°C. The brand Virtue, renowned for its exclusive patent Alpha Keratin 60ku, offers a shampoo specialized in scalp clarification and tip fortification, making it an optimal choice for reversing damage caused over time. Kérastase Discipline Keratin Thermique styling creams receive positive reviews for their ability to create a protective shield around strands, resulting in smooth, humidity-resistant hair with reduced drying time. Viral keratin treatments promise similar results to salon treatments, with effects lasting up to three months, requiring only spraying, rinsing, blow-drying, and sealing by smoothing. The OGX Brazilian Keratin Smooth conditioner combines keratin proteins with hydrating coconut and avocado oils, as well as cocoa butter, in a balanced pH formula, ideal for sensitive scalps and quick drying. Pantene Repair & Protect Hair Oil with Vitamin E is an economical option in spray form, which instantly nourishes wet or dry tips and begins the process of repairing damage immediately. Philip Kingsley Body Building Shampoo busts the myth that keratin could make hair greasy or sticky, promising volume and vitality without weighing strands down, making it ideal for individuals with fine hair. Shower-melt masks containing hydrolyzed keratin and marula oil act synergistically to detangle, soften strands, and prevent frizz, ensuring a polished appearance. [1]
