Review: No good for African hair. - No change was seen after use.
Review: Highly recommend to tame your curly, freeze hair - This was easy to use and has worked great on my naturally curly hair. I use it at the beginning of summer when the humidity hits to calm my freeze down. I get about three uses out of the one bottle and I have shoulder length, thick hair. The smell is strong when you flat iron it but not unbearable, I turn the vent on in my bathroom and it is fine. The results last me about three months if I only leave it on my hair for a day or two before the first wash. If I can I leave it for at least three days and get an extra month out of it. Highly recommend.

### ⭐⭐⭐⭐⭐ Keine Wirkung – Geldverschwendung
*by C***B on 30 June 2026*

Ich bin sehr enttäuscht von diesem Produkt. Die Flaschen sind sehr klein und die Menge reicht kaum aus. Ich habe das Produkt wie empfohlen verwendet, aber leider überhaupt keine Wirkung festgestellt. Für den Preis lohnt es sich meiner Meinung nach nicht. Ich werde dieses Produkt definitiv nicht noch einmal kaufen und kann es leider nicht weiterempfehlen.
