Kerastia | Product description | Bestseller 2025

Is your hair dry and lacking in shine?

Are you tired of breakage and split ends?

Are you looking for an intensive and effective treatment that really works?

Daily drying, styling, sun exposure, wind, and even hard water… All these factors cause your hair to lose its natural elasticity! They become rough to the touch, dull, and difficult to style. You might notice that more hair is left behind on the brush after brushing or that the ends of your once-beautiful hair break off more quickly than you can trim them. These are some of the reasons why you are seeking an effective and modern solution. One of the answers to these issues is Kerastia serum&mask — a contemporary and intensive daily care solution. This product delivers professional care that restores natural harmony to both your hair’s length and the scalp, in perfect harmony with nature. No unnecessary additives, no excess cosmetics, and no empty promises. Kerastia stands on its own, with results visible in the smiles of men and women across Europe.

A selection of 5-star reviews for Kerastia

A hair mask? What is that? Now I know!

“I had never used hair masks before because I had no idea they even existed! I was at the point where I was washing my hair every day with just shampoo and occasionally using conditioner—that was the extent of my hair care routine. I had no idea that a mask could make such a difference!”

“Kerastia caught my attention because it was named Kerastia serum&mask—a catchy name, yes, but it seemed like it combined two products in one. I thought: ‘Since I’m trying something new, I’d better choose a product that does more than just wash my hair.’ Sure enough, from the first application, it was a whole new experience. The gentle formula absorbed quickly into my scalp. After the first use, my hair felt smoother than ever. I thought it was just a temporary effect, but it was like that every time I used it. I didn’t use it daily, yet my hair still looked healthy and felt pleasant to the touch. After a few weeks, it was noticeably less frizzy, softer, and easier to manage. I realized this wasn’t a coincidence. My previous products must have been of low quality, and I didn’t truly understand what proper hair care was until now. I can’t imagine going back to the old methods. I highly recommend Kerastia to anyone with any kind of hair problems.” — Giulia, Milan

Hair care for men is more important than you think

“For most of my life, I didn’t care about hair products. I thought it was something unnecessary, something only women used. After all, it’s just hair, right? But then, it started falling out at a rate I couldn’t ignore. It was thinning, weak, and I was losing more and more hair with every wash. That’s when I realized I needed to do something.”

“I didn’t want to go to the pharmacy because it felt embarrassing and ‘unmanly.’ After some research, I bought Kerastia. I was skeptical, but I was desperate to at least keep my hair looking presentable. To my surprise, I wasn’t disappointed. Not only did my hair stop falling out so excessively, but the grey faded a little too. Now, I feel more confident knowing that I look better. If you think, as I did just a few weeks ago, that hair care isn’t ‘manly,’ you’re missing out on the benefits of taking care of your appearance.” — Marco, Rome

What is Kerastia?
How can it help you?

Kerastia is an advanced hair care product that combines the benefits of a serum and a hair mask. It is a complete solution that works on a deeper level, offering intense regeneration and protection that traditional shampoos and conditioners cannot match. The key difference between Kerastia and standard cosmetics like shampoos or soaps is how it works.

Shampoos and soaps are designed primarily to cleanse the hair, removing dirt, excess sebum, and other impurities. Although some may have moisturizing ingredients, their action is mainly limited to surface-level cleaning and conditioning. Kerastia’s serum and mask, however, work in multiple ways. Not only does it cleanse, but it also regenerates, nourishes, and strengthens hair from the inside.

While shampoos are suitable for daily use, Kerastia is a solution designed for more advanced care, focusing on deep regeneration, the restoration of hair structure, and long-term protection from damage. It’s a choice that combines the benefits of both a mask and a serum to help make hair stronger, healthier, and shinier.

The top 5 reasons why Kerastia is your perfect hair care ally

• Prevents hair loss and strengthens hair follicles: Kerastia stimulates scalp microcirculation, providing essential nutrients for strong, fall-resistant hair growth.
• Rebuilds damaged hair structure: Thanks to its advanced formula with keratin and vitamins, it penetrates deep into the hair, rebuilding it from within. Hair becomes smoother, more resilient, and less brittle.
• Increases volume and density: If your hair has become thin and lifeless, Kerastia helps add volume, making your hair appear fuller and thicker over time.
• Improves scalp hydration and prevents dryness: As a combined serum and mask, it moisturizes both your hair and scalp, combating dryness and flaking, which is crucial for resolving trichological issues.
• Protects against harmful external factors and styling: Kerastia creates a protective layer that shields your hair from UV rays, pollution, and frequent styling damage.

Kerastia serum & mask ingredients – harnessing the power of nature

Kerastia is not about empty promises. Its roots trace back nearly a decade, when the first results of combining ingredients in optimal proportions started to show. Below are the exceptional ingredients in the 2025 version of Kerastia serum&mask:

• Sweet almond oil: Rich in vitamins E and A, as well as fatty acids, it deeply moisturizes the hair, prevents dryness, and strengthens the roots, promoting growth while protecting against UV rays and pollution.
• Hydrolyzed corn protein: Strengthens hair structure, protecting it from breakage and mechanical damage, while creating a barrier that retains moisture and provides elasticity and shine.
• Radish root fermentation filtrate: Intensively hydrates, promotes regeneration, and imparts a healthy shine. Its antibacterial properties help maintain scalp balance for better hair growth.
• Aloe vera extract: Deeply moisturizes the hair and scalp, soothes irritation, and combats dandruff. The vitamins and minerals in aloe support hair regeneration, leaving it soft and healthy-looking.
• Shea butter: Acts as a natural protective barrier, preventing dryness and shielding hair from the damaging effects of UV rays, pollution, and wind.
• Vitamin E: A powerful antioxidant that protects hair from free radicals and harmful external elements. It hydrates, regenerates hair, and improves scalp circulation to stimulate healthy growth.

Effects of Kerastia serum & mask

With regular use, Kerastia delivers both immediate and long-term results. While hair damage can take weeks, months, or even years to develop, full restoration requires patience and a consistent approach.
