Yes, L'Oréal Professionnel Liss Unlimited Serum can help manage and improve very dry hair. Enriched with Evening Primrose Oil, it deeply nourishes, moisturises, and softens the hair while adding natural shine, and also provides frizz control and protection against humidity. For best results, apply a small amount to damp hair, focusing on the mid-lengths and ends, and avoid the scalp to prevent greasiness. Regular use can enhance hair texture and manageability, especially when paired with a gentle shampoo and conditioner. Additionally, maintaining a balanced diet, staying hydrated, and minimising heat styling support overall hair health and strengthen results.
