LASIO Mocha Silk Treatment is our MOISTURIZING formula! It also contains cacao oil, which drenches dry strands in moisture. Mocha Silk is great to recommend to clients with naturally resistant hair, so while it isnt stronger in terms of formaldehyde content, it is EFFECTIVE at smoothing resistant hair. This treatment is excellent for extremely dry or damaged hair, or for those with thick, coarse and very curly hair looking to achieve a straighter look. Cacao oil's smooth texture, enticing aroma, and emollient properties contain natural antioxidants that strengthen and smooth hair. Cacao Oil works to retain moisture and provides a breathable barrier to protect hair that is dry or over-processed against environmental stress and fading.
