The goal is to strengthen the natural structure of the curls and maintain the hair's moisture balance.

    Although products according to the curl method are aimed at curly hair, they are also suitable for straight hair:

    1. Moisturizing: Since the curl method focuses on moisturizing, these products are also excellent for straight hair that needs extra moisture.

    2. Gentleness: Our products do not contain raw materials that can damage the hair structure. This makes them also suitable for more sensitive hair types.

    3. Frizz control: Our products help smooth the surface of the hair and control frizz.

    So Sumilay's products offer versatile benefits for different hair types, supporting the hair's natural beauty.

    Tästä hoitoaineesta on tullut luottotuote; pikkuruinen määrä riittää hoitamaan laineikkaat hiukset latistamatta.

    Vaikuttaa erinomaiselta

    Parin viikon käytön perusteella vaikuttaa riittoisalta loistotuotteelta! Ei latista hentoja hiuksia ja tuntuu selvittävän pestyjä takkuhiuksia ällistyttävän hyvin. Curly girl-tehoista en osaa sanoa t. Suorahiuksinen

    Tuulikki Silen

    Minulla aine toimi ja on hyvin miellyttävän tuntuista ja ihanan tuoksuista.



    Hyvä tuote!

    Kosteuttaa hyvin eikä jätä hiuksia rasvaisen näköisiksi!
