AVEDA Botanical Repair Overnight Strengthening Serum — 1 fl oz | Bond-Building, Reduces Split Ends

This lightweight, nearly all-natural serum works overnight to rebuild hair’s structure and smooth the surface so you wake to softer, stronger-looking hair. Powered by plant-derived technologies and a macro-green oil blend, it targets core damage inside the strand, nourishes the cortex, and forms a protective botanical layer on the cuticle. The formula includes nangai oil to help bring split ends together and a subtle Pure-Fume scent made from organic floral and plant essences.

How does this serum rebuild hair while I sleep?

The serum uses a bond-building plant molecule that helps form new hydrogen bonds deep within the hair cortex. Simultaneously, nourishing oils replenish essential lipids and amino-acid–supporting ingredients fortify internal structure, so repair happens at multiple levels overnight.

• Bond-building molecule creates new internal hydrogen bonds.
• Macro green blend (avocado, green tea, sacha inchi) replenishes lipids and nutrients.
• Overnight application allows continuous repair without rinsing.

Will it actually reduce the appearance of split ends by morning?

The serum’s nangai oil smooths and helps seal frayed strand tips, visibly reducing the look of split ends after one night in lab testing. Results depend on existing damage level, but many users report noticeably smoother ends and less visible splitting after a single use.

• Nangai oil helps bring split ends together and smooth surface fibers.
• Invisible botanical outer layer minimizes friction while you sleep.
• Can be used nightly or as a daytime spot treatment for visible ends.

Is this suitable for my hair type and styling routine?

The lightweight serum is formulated for most hair types and works under pillow or while styling the next day without residue. It’s designed to be applied to mid-lengths and ends, so it won’t weigh down fine hair when used sparingly and supports thicker or chemically treated hair by reinforcing internal bonds.

• Apply to lengths and ends—avoid the root area for fine hair.
• Non-greasy finish lets you style as usual in the morning.
• Safe for color-treated and chemically processed hair when used as directed.

What’s in the formula and what’s left out?

More than 99% of the ingredients come from plants, water, or non-petroleum minerals, and the formula combines botanical oils with plant-derived bond builders and smoothing complexes. Aveda excludes many common additives to keep the serum plant-forward and gentle on hair.

• Key actives: plant-based bond-building molecule, nangai oil, avocado, green tea, sacha inchi oils.
• Nearly 99% naturally derived per ISO 16128.
• Formulated without silicones, parabens, phthalates, mineral oil, formaldehyde donors, SLS/SLES, and synthetic fragrances.

Who is this for? This overnight serum is aimed at anyone looking to strengthen damaged, dry, or split-prone hair without heavy buildup—especially people who color, heat-style, or chemically treat their hair. If you want a plant-forward treatment that works while you sleep to reinforce hair from the inside out, reduce the visible appearance of split ends, and leave strands smoother for styling, this concentrated Aveda formula is a targeted option. Use nightly or as-needed on lengths and ends; style normally in the morning.
