Born in 1964 in Paris, Kérastase Paris was initially positioned as a hair salon-level high-end toiletry brand. After developing the world's first hair mask, Kérastase's sales skyrocketed, and its style became even higher, making it the "Rolls-Royce" of the hair care industry. At present, Kérastase Paris is a cleaning and care brand at the top of the pyramid, and its products have won many awards such as the InStyle UK Beauty Buys Award, the Fashion COSMO Beauty Award, the WWD Beauty Best Product Award in Japan, and the VOGUE Best Hair Product Award.
 
There is no one panacea shampoo in the world that can achieve the ideal treatment effect for all types of hair, and most open brands only adjust the amount of ingredients for different products due to cost considerations, and even only change the pigment and fragrance. Kérastase's success lies in the fact that it has launched more than 10 series of products with very different ingredients and formulas, all of which are first-class cleaning and care products.
 
Before choosing a shampoo, you need to know more about your hair. In fact, the vast majority of people have normal hair, and they only need to keep their hair clean every day. Unless there is a significant history of hair loss, pathology, or family genetics, don't easily classify yourself as oily hair, as the pursuit of oiliness will irritate the scalp and increase oiliness. For truly oily hair, Kérastase's dual-function shampoo is a surfactant with SLES that removes oil and no longer lubricates the ends for a noticeable dry feel. This product is not recommended for people with normal hair, otherwise they will experience the discomfort of being too dry.
 
Dry hair is characterized by being extremely difficult to comb, with high friction and prone to knots and frizz. Kérastase's Nourishing Constant Care and Oli Shun Gentle and Soothing Moisturizing are three shampoos for different levels of dry hair, among which the nourishing and constant care of the white bottle is more suitable for dry and obvious hair, and polyquaternary ammonium salts and silicone oil can play a good role in hair lubrication. The orange bottle of Ollie is more suitable for sofa people. The so-called sofa is a frizzy, curly hair type that resembles a "steel wool ball", most of which are derived from genetics. The orange bottle is effective in subduing this messy hair tip and increasing the softness of the hair. Blue Bottle's soothing and moisturizing shampoo is not added with silicone oil and is slightly less lubricating than the other two, making it suitable for milder dry hair.
 
The Color Care series is Kérastase's signature product, which is far more effective than similar products in protecting the color of hair color. Red Bottle's Brilliant Constant Care Shampoo is formulated with silicone oil and rice bran oil, which can smooth the hair cuticles that are opened during the hair dyeing process to a certain extent, and increase the shine of the colored hair. Hair coloring will gradually deviate from the first color of choice over time and light, and the more vivid the color, the more obvious the fading effect. This color care product is added with vitamin E acetate (Tocopheryl Acetate), which has a good antioxidant effect and delays the oxidation of hair color pigments to a certain extent. Cinnamon acid is an excellent ultraviolet absorber, and is one of the most widely used sunscreen ingredients, which can reduce the impact of ultraviolet rays on hair coloring and lock in color. However, no matter how good the product is, it can't protect it from the sun, and people who have dyed their hair should pay special attention to sun protection, and a parasol or hat is the most ideal way to protect it.
 
Although the effect of dyeing and perming can play a role in improving the image, too frequent dyeing and perming will damage the ends of the hair and reduce the texture of the hair, so it is not recommended to dye and perm more than 5 times in half a year. For those who dye and perm twice in half a year, Kérastase has launched a green bottle of strong repair shampoo, which combines polyquaternary ammonium salt with hydroxypropyl guar gum hydroxypropyltrimonium chloride to keep the hair lubricated and avoid further damage from opening the hair cuticle; For those who have been dyed and permed more than twice in half a year, cyan toothpaste-like silk rejuvenation is a more suitable choice, lubricating some hair strands after hair cuticle loss through aminodimethicone and dimethicone. Platinum Rejuvenating Shampoo has a certain styling effect, this shampoo is especially suitable for men with fine and flat hair, after use, the hair will have a clear "fried hair" feeling, the hair is elastic and firm, and the hair can also maintain the styling effect to a certain extent after bed rest.
 
Almost all Kérastase products contain salicylic acid. Salicylic acid dissolves the stratum corneum and has an antibacterial effect, which is often added to skin care products, and often acts as an anti-dandruff ingredient in shampoos in the past, but the effect is poor and irritating. The amount of salicylic acid in Kérastase is small, and the purpose is not to remove dandruff, but mainly to play an anti-inflammatory and conditioning role. People who need to get rid of dandruff can choose Kérastase Anti-Dandruff Purifying Shampoo, which is added with zinc pyrithione, which has a better anti-dandruff effect. It should be noted that all products with salicylic acid (or sodium salicylate) are labeled "not for children under 3 years old", and women who are pregnant or breastfeeding should also try to avoid it, so it is recommended that these people stop using Kérastase shampoo for a short time.
 
Kérastase shampoos vary in texture, ranging from a moisturizing lotion to a viscous paste, all of which are more economical. Each fragrance is different, mostly presented as a light smell of flowers, there are a variety of high-end fragrances such as vetiver iris, water lily lily fragrance, etc., which can cater to the preferences of most consumers. A variety of silicone-free products are properly adjusted in terms of cleaning power and washing feeling, without the dryness and frizz of general silicone-free products after use, but are light and comfortable, smooth and easy to care for. The price of Kérastase shampoo remains high, with 250ml priced at around 240 yuan and 500ml priced at 380 yuan.
