Hair fillers are the perfect solution for hair that breaks easily. Here are the best ones

Just as a good facial filler can transform the look of the skin in a matter of minutes, a good hair filler can work wonders in an instant. After the treatment, the hair becomes smoother, stronger and shinier, almost like in the commercials I watched in my youth. However, unlike skin, hair treatments do not use hyaluronic acid. Instead, hair fillers contain nourishing and restorative ingredients that restore the hair’s natural shine.

The function of hair fillers applied before washing is not only to enhance the appearance of the strands. They precisely fill in damaged areas of the hair, repair brittle ends and strengthen the internal structure of each strand. Hair health and quality improve with every use. What I personally noticed when using fillers is that the hair becomes stronger, more manageable and more resistant to everyday breakage. For my fine hair, breakage was the main issue, which hair fillers resolved in a short time. At times, I could even skip conditioner and mask after washing, because the hair was already sufficiently smoothed by the filler, even though I used it before shampooing. Still, consistency is key.

Just like with facial cosmetic treatments, regular use delivers long lasting results. Over time, the hair becomes vital, more resilient and incredibly beautiful. Hair fillers are an ideal pre wash treatment for hair that breaks easily, loses volume, looks tired or is extremely fragile and dry. They deeply restore and strengthen each strand, bringing back the vitality the hair deserves. They are suitable for all hair types, from fine and fragile to thick and curly, and can be used on their own or combined with a conditioner for maximum effect. Below, we bring some of the best formulas for every hair concern and need.

The best hair fillers

1/ Best for removing limescale buildup from hair: Kérastase Paris Première Concentré Décalcifiant Ultra Réparateur Hair Treatment

In just a few minutes, you get a smooth, elastic and luxuriously glossy salon effect that is usually achieved only after a professional treatment.

Enriched with patented ingredients, this pre wash filler treatment “refills” one million micro cracks in just one minute. The hair becomes stronger and less prone to breakage, incredibly hydrated, smooth and easy to detangle.
