The Fortifying and Revitalizing Treatment Shampoo integrates the restorative features of four unique honeys, chosen by Guerlain Research for their combined benefits on both hair and scalp. This shampoo offers a gentle cleanse while rejuvenating the scalp, which is crucial for healthy hair growth. From the very first use, users can see noticeable improvements in hair strength and shine, as it becomes more elastic and voluminous. Its rich, honey-like formula, crafted with Guerlain's expertise in product development, is made up of 87% naturally sourced ingredients and is gentle enough for everyday use. Inspired by the properties of honey from beehives, this cleansing treatment is formulated as an emulsion that transforms into a luxurious foam upon contact with water, providing a smooth application over the scalp and hair. After a decade of exploring the skin-enhancing qualities of honey, Guerlain has introduced the innovative Blackbee Honey Repair Technology, which merges the four selected honeys with active components inspired by dermocosmetics. This treatment delivers dual benefits for both the hair and scalp, utilizing the potent honeys in conjunction with phytoceramides for restructuring, arginine for smoothing, D-panthenol for enhancing strength, and Cassia alata extract to safeguard color. Test results demonstrate that after one month of use, women observed significant improvements in their hair, noting a revival (+35%), increased strength (+24%), enhanced softness (+31%), greater brilliance (+36%), and improved elasticity (+26%). These assessments were self-reported by 32 women in France who used the product three times a week for a month.
