Aveda Botanical Repair Strengthening Overnight Serum — 3.4 fl oz, Bond-Building & Split-End Repair with Nangai Oil

Aveda Botanical Repair Strengthening Overnight Serum is an overnight bond-building treatment that strengthens hair, repairs three structural layers, and visibly reduces split ends while you sleep.

Designed as a leave-in night serum, this plant-powered formula works overnight to restore hair integrity and smooth strands using Aveda’s Bond-Building 3-Layer Repair system and nourishing oils. Lightweight and 99% naturally derived*, it forms an invisible protective veil to minimize friction and help prevent new damage from daily styling and environmental stressors.

How does this serum rebuild damaged hair while I sleep?

The serum uses a plant-derived bond-building molecule to form new hydrogen bonds deep inside the hair cortex, reinforcing the fiber. Simultaneously, it strengthens the inner structure and smooths the cuticle for improved manageability by morning.

• Bond-Building 3-Layer Repair targets cortex, cuticle, and outer layer.
• Creates new hydrogen bonds to reinforce hair fibers.
• Overnight application lets ingredients penetrate without rinsing.

Will it really reduce the appearance of split ends overnight?

Nangai oil in the formula helps bring split ends together by smoothing and sealing strand tips, producing a visible reduction in split end appearance after one night in lab testing. Results can vary depending on hair condition and previous damage.

• Clinically shown in testing to reduce split-end appearance by up to 84% overnight**.
• Nangai oil smooths and seals strand tips for a neater finish.
• Use nightly or as a daytime spot treatment on ends.

What plant ingredients nourish and protect hair in this serum?

The formula combines a macro green blend—certified organic avocado, green tea, and sacha inchi oils—with a plant-based complex that forms an invisible botanical outer layer. These botanicals replenish essential lipids, soften hair, and reduce friction to help prevent future breakage.

• Organic avocado oil replenishes moisture and lipids.
• Green tea and sacha inchi oils help soften and detangle.
• Botanical outer layer helps shield hair from mechanical damage.

How do I use it and what should I expect the next morning?

Apply the serum to lengths and ends at bedtime and leave it in—no rinsing required. In the morning, hair should feel smoother, appear more polished, and be easier to detangle and style; continue regular styling or use as a daytime repair touch-up when needed.

• Apply to dry or damp lengths and ends before bed; do not rinse.
• Use a small amount on problem areas during the day for targeted repair.
• Style as usual in the morning; expect softer, more manageable hair.
