Our Curl Stretching Cream smoothing treatment gently stretches out 4A-4C curls for quicker haircare. Stretched curls last up to a month, giving you less breakage, less knotting and faster dry time while keeping bounce and volume.
The Samuel’s Science Curl Stretching Cream is designed to reduce curl for 4A-4C hair by 50%-90% by using a naturally occurring amino acid. Sulfur (think of a hot spring) is the key ingredient that allows for reshaping of the hair by re-forming the core bond in your strands that creates hair shape.
100mL is enough for one treatment. We recommend monthly use for best results.
