Universal Defense Serum for Unbalanced Scalps

Size: 90ml / 3.04fl.oz

Kerastase Specifique Potentialiste Serum is designed for unbalanced scalps that tend to be dry, sensitive or oily to defend against discomfort and uncomfortable feeling. It may also be used on normal scalps to reinforce and maintain the scalp barrier and to create the ideal environment for hair that is stronger, healthier, and more gorgeous. Microbiome Science lies at the heart of Kerastase Potentialiste Serum, which is crucial for human development, immunity, and nutrition. When the microbiota is in balance, the scalp defends and cures itself, making it your constant companion in the pursuit of a healthier scalp. The proprietary Microbiome research enabled the development of a flawless, fast-absorbing gel-texture serum with two key ingredients: Bifidus Prebiotics Fractions, which nourishes & cares for the scalp's good bacteria to maintain strong barrier, and Vitamin C that neutralizes the effect of daily aggressors, which can lead to imbalance in the scalp. Kerastase Potentialiste Serum protects the scalp microbiome from daily external stressors, which are a natural part of your very own ecosystem of living bacteria. This lightweight formula creates a well-kept, hydrated, and cooling sensation on the scalp that is reported by 73% of users. Hair feels airy and the scalp feels chilled and stimulated with a long-lasting fragrance of Kerastase Potentialiste Serum.

    Potentialiste serum

    Posted by Helen on 10th Dec 2021

    I have extremely thick and curly hair and I wash it only 2 twice per week so my scalp got itchy and flaky. This serum has changed my life. It has completely rid me of my scalp issues. I love the refreshing and invigorating scent that this product leaves on my hair. Highly recommend this! Thank you for the free samples.
