Aveda Botanical Repair Strengthening Overnight Serum 3.4 fl oz — Bond‑Building, Nangai Oil for Split Ends

Aveda Botanical Repair Strengthening Overnight Serum is an overnight bond-building treatment that helps repair damaged hair and visibly reduce the appearance of split ends while you sleep.

Designed for hair weakened by heat, styling, color and daily wear, this 99% naturally derived* serum works while you rest to rebuild structural integrity and smooth the surface of each strand. Its plant-powered formula combines a bond-forming molecule, a nourishing macro green blend and nangai oil to target core damage, replenish essential lipids, and seal the cuticle. The result is softer, easier-to-manage hair with fewer visible split ends.

How does this treatment rebuild hair bonds overnight?

The serum contains a plant-based bond-building molecule that forms new hydrogen bonds deep in the hair cortex, helping reinforce the fiber from within. While you sleep, these micro-repairs accumulate to strengthen fragile areas and improve resilience.

• Bond-building molecule creates thousands of new hydrogen bonds
• Works on the cortex to reinforce internal structure
• Applied at night to maximize uninterrupted repair time

What ingredients smooth and reduce the look of split ends?

Nangai oil is central to sealing and smoothing strand tips to diminish the appearance of splits. A macro green blend of organic avocado, green tea and sacha inchi oils nourishes, softens and detangles while a plant-derived outer complex forms an invisible protective layer.

• Nangai oil helps bring split ends together and seal tips
• Avocado, green tea and sacha inchi oils replenish lipids and softness
• Plant-based outer layer minimizes friction and future damage

How do I use it and when will I see results?

Apply the serum to lengths and ends at bedtime—do not rinse—and style as usual in the morning. Many users notice improved smoothness after the first application and laboratory testing shows an 84% reduction in the visible appearance of split ends after one overnight use**.

• Apply to towel-dried or dry lengths and ends before bed
• Leave in overnight; style in the morning without rinsing
• Can be used daily for ongoing split-end management
