Frequently Asked Questions

How does the ABC 24/7 Night & Day Serum repair damaged hair while I sleep?
The serum's 7% Bonding Care Complex, along with citric acid, works while you sleep to penetrate the hair fiber and rebuild weakened bonds. It is the first bonding serum designed for round the clock repair, so it keeps working on strength and hydration overnight, leaving hair shiny and manageable for up to 72 hours.
What makes the Bonding Care Complex different from a regular hair oil or leave-in treatment?
Unlike a standard oil or leave-in, the Bonding Care Complex combines citric acid, polyglutamic acid, and squalane to actively rebuild the hair's internal bonds rather than just coating the surface. This helps restore up to 9x stronger hair and 3x more hydration when used as part of the full Acidic Bonding Concentrate system.
How do I use the ABC 24/7 Night & Day Serum both at night and during the day?
Apply a quarter sized amount to clean, dry, or damp hair and do not rinse it out. At night, apply generously from mid-lengths to ends to maximize bond repair and hydration while you sleep. During the day, use a smaller amount as needed for instant frizz reduction, conditioning, and shine.
How much frizz reduction can I expect after using this serum?
Consumer testing shows a 72% reduction in frizz after just 8 hours of use, based on continued use of the ABC shampoo, conditioner, and serum system. 92% of users also agreed their hair looked and felt healthy after 24 hours of continuous repair.
Is the ABC 24/7 Night & Day Serum safe for color-treated and bleached hair?
Yes, the serum is formulated to support processed and color-treated hair. It helps repair daily damage overnight while protecting against the added stress of heat styling, environmental exposure, and everyday wear and tear, making it well suited for color-treated and chemically processed hair.
