The latest addition to Aveda's Botanical Repair haircare line-up is the Strengthening Overnight Serum. Enriched with nangai oil, the multi-benefit leave-in treatment helps to reduce the appearance of damage and flyaways, while visibly strengthening and smoothing unruly strands. Designed to protect against heat up to 230°, the lightweight formula envelops each strand in an invisible coat to help prevent visible damage whilst you sleep. The serum is suitable for all types and textures, leaving hair smooth and glossy after just one use.
