Acidic Bonding Curls Duo

The Acidic Bonding Curls range is for people with damaged, chemically processed wavy, curly, and coily hair. It is best recommended for those with curl patterns 4-8 (3A-4C) but is suitable for curl patterns 3+ (2B and beyond). It is safe for color-treated hair.

Yes, Acidic Bonding Curls can be used on hair that’s been relaxed. However, these formulas have been designed to provide positive attributes such as frizz control and definition to all curl patterns. Hair that has been relaxed to the point that there is no longer a curl pattern might benefit from using Acidic Bonding Concentrate as an alternative.

Formulated with a Bonding Care Complex, Citric Acid, and Glycine, Acidic Bonding Curls are for processed, damaged curly, and coily hair. All Soft Mega Curls is formulated with a Nourishing Complex and Aloe for extremely dry curly and coily hair.

Over time, silicones can build up within the hair resulting in unwanted weight. Acidic Bonding Curls focuses on restoring curls with lightweight moisture while strengthening the hair from the inside to achieve bouncy, nourished hair.

​The shampoo and conditioner formulas are free of sulfate cleansing ingredients (SLES and SLS). All are vegan formulas with no animal-derived ingredients. ​

Alpha hydroxy acids (AHAs) are found in several hair and skin cosmetic products, as they are known to help cleanse without stripping moisture. The US FDA advises that all cosmetic products containing AHAs that are topically applied to the skin have the potential to increase the skin’s sensitivity to sunlight and recommends very specific usage instructions on these types of products. Acidic Bonding Curls products are hair products that contain the AHA known as citric acid and are not intended for topical application to the skin. However, unintentional exposure of the skin may occur during regular use and that’s why the FDA’s recommended statements are included on the packaging for your understanding and awareness.
