Sulfate-free DD shampoo contains biodegradable surfactants of plant origin. A combination of skin-safe surfactants allows you to gently but effectively wash your hair and scalp. The shampoo contains a nutrient that strengthens hair, makes it smooth, soft and easy to comb. Olive oil is a source of polyunsaturated fatty acids Omega 3 and 6, has a softening effect and increases the plasticity of the hair shaft. Hydrolyzed vegetable protein partially replenishes lost keratin, thickening hair. Salicylic acid has an anti-inflammatory and antibacterial effect - removes stubborn scales, softens and exfoliates keratinized areas (the keratolytic effect helps to exfoliate dead tissue faster). The shampoo maintains the pH of the scalp and hair. The series, unlike other products in the Alan Hadash product line, is less perfumed, has a pleasant, unobtrusive fine fragrance, which is noticeable during use and practically does not remain on the hair after drying. Designed for daily use.
