Kerastase is a professional luxury hair care brand that has been a staple in high-end salons since 1964. Known for its science-based formulas and targeted treatments, the brand offers a wide variety of products designed to address specific hair concerns. Because the product range is so extensive, choosing the right items for your hair type can sometimes feel overwhelming.
This guide provides a straightforward breakdown of the different Kerastase collections and how to use them effectively. By understanding the purpose of each line, you can build a customized routine that improves the health and appearance of your hair. Whether you are dealing with dryness, damage, or color fading, there is a specific solution available.
Understanding the Kerastase Approach to Hair Care
Kerastase categorizes its products into “ranges” or “collections,” each color-coded for easy identification. The brand follows a signature three-step routine: cleanse, treat, and prime. This method ensures that the hair is properly prepared, nourished, and protected from external stressors like heat and humidity.
When browsing products, you will notice specific French terms used for different types of formulas. A “Bain” refers to a shampoo, a “Fondant” is a lightweight conditioner, and a “Masque” is a deep-conditioning treatment. Understanding these terms helps you navigate the labels more confidently when shopping for your hair needs.
Identifying Your Hair Type and Concerns
Before selecting a product, it is important to accurately assess your hair’s current condition. Hair needs can change based on the season, chemical treatments, or lifestyle factors. Ask yourself if your hair feels brittle, looks dull, or if you are struggling with specific issues like an oily scalp or thinning strands.
Common hair concerns usually fall into one of several categories: hydration, repair, color protection, or volume. Kerastase designs its collections to target these specific areas. Once you identify your primary concern, you can look for the corresponding color-coded line to find your ideal products.
The Nutritive Range: For Dry and Sensitized Hair
The Nutritive collection is one of the brand’s most popular lines, easily recognized by its white packaging with orange accents. It is specifically formulated to provide intense nourishment to dry hair. These products use ingredients like plant-based proteins and niacinamide to restore moisture and softness.
This range is divided into sub-categories based on how dry the hair is. Some products are designed for fine hair that needs moisture without being weighed down, while others are richer for thick, extremely parched hair. If your hair feels rough or tangles easily, the Nutritive line is often the best place to start.
The Resistance Range: For Damaged and Weak Hair
If your hair has been weakened by heat styling or chemical processing, the Resistance range is the appropriate choice. These products come in light green packaging and are designed to rebuild the internal structure of the hair fiber. They focus on strengthening the hair to prevent breakage and split ends.
The Resistance line features different levels of intensity. The Force Architecte products are meant for hair with mild to moderate damage. For severely damaged or over-processed hair, the Therapiste products offer a more intensive repair system. Using these products consistently can help restore elasticity and resilience to fragile strands.
The Chroma Absolu Range: For Color-Treated Hair
Color-treated hair requires specialized care to maintain vibrancy and prevent damage caused by dyes. The Chroma Absolu range, found in dark pink packaging, uses healing acids to protect the hair. It focuses on reducing frizz and preventing color oxidation, which can cause hair to look dull or brassy.
This line is particularly effective because it addresses the porosity of the hair. By sealing the hair cuticle, it keeps the color molecules trapped inside for a longer period. It also provides essential hydration to counteract the drying effects often associated with permanent hair coloring.
The Blond Absolu Range: For Blonde and Bleached Hair
Blonde hair, whether natural or lightened, has unique requirements. The Blond Absolu collection comes in light purple packaging and is designed to provide deep hydration and neutralize unwanted yellow or orange tones. It contains hyaluronic acid and edelweiss flower to soothe sensitized hair fibers.
This range includes “Ultra-Violet” products, which contain purple pigments to keep blonde shades cool and bright. It also offers “Cicaflash” treatments that provide the restorative power of a mask with the lightweight feel of a conditioner. This is an essential line for anyone looking to maintain a healthy, vibrant blonde.
The Genesis Range: For Hair Fall and Breakage
Hair fall can occur due to stress at the root or breakage along the hair shaft. The Genesis range, identified by its pale pink bottles, offers a dual action to treat both causes. It strengthens the hair fiber to reduce breakage while stimulating the scalp to support healthy growth.
These products are formulated with ginger root and aminexil to improve hair retention. Unlike some heavy hair-growth products, the Genesis line is designed to be lightweight and suitable for daily use. It is an excellent choice for those noticing more hair than usual in their brush or shower drain.
The Discipline Range: For Frizzy and Unruly Hair
Managing frizz and flyaways is the primary goal of the Discipline range, which features peach-colored packaging. These products use “Morpho-Keratine” technology to coat each hair fiber, providing smoothness and control without making the hair feel stiff or greasy.
The Discipline line is ideal for those with curly or wavy hair who want to define their natural texture while reducing bulk. It also includes products specifically for blow-drying, which help speed up the styling process and protect against humidity throughout the day.
How to Build a Kerastase Routine
To get the best results, you should follow the brand’s recommended three-step process. Start with a Bain (Cleanse). Apply a small amount to wet hair, massage the scalp thoroughly, and rinse. Many professionals recommend a “double cleanse,” where you wash twice to ensure all product buildup is removed.
The second step is to Treat. For daily use, apply a Fondant (Conditioner) to the mid-lengths and ends. Once a week, swap the conditioner for a Masque. Deep treatments should be left on for five to ten minutes to allow the ingredients to penetrate the hair shaft deeply.
The final step is to Prime. This involves applying a leave-in cream, oil, or spray to damp hair before styling. These products, often called “Thermiques,” provide heat protection and seal the cuticle. This step is crucial for maintaining the benefits of the cleansing and treating stages.
Tips for Getting the Most Out of Your Products
Because Kerastase products are highly concentrated, a little goes a long way. Using too much product can lead to buildup and make the hair feel heavy. Start with a coin-sized amount and add more only if necessary. It is also helpful to emulsify the product in your hands with a little water before applying it to your hair.
Always rinse your hair thoroughly, especially after using a mask. Any residue left behind can dull the hair’s shine. Additionally, pay attention to the water temperature; using lukewarm water instead of hot water helps keep the hair cuticle closed, which preserves moisture and color.
Where to Purchase Authentic Kerastase Products
To ensure you are getting genuine products, it is best to purchase from authorized retailers. This includes professional hair salons, the official Kerastase website, and well-known beauty retailers. Purchasing from unverified third-party sellers online can sometimes result in receiving expired or counterfeit products.
If you are unsure which range is right for you, many authorized salons offer professional hair consultations. A stylist can examine your hair and scalp to recommend the exact combination of products that will work for your specific needs.
Conclusion
Kerastase offers a professional-grade solution for nearly every hair concern, from extreme damage to color maintenance. By identifying your primary hair goals and following the three-step routine of cleansing, treating, and priming, you can significantly improve the health of your hair. Remember that consistency is key to seeing long-term results with any hair care regimen.
