Why Choose Rausch Damaged Hair Repair Serum with Amaranth? When your hair needs an extra boost of nourishment, RAUSCH Repair Serum with Amaranth offers the perfect solution. This rich, leave-in serum strengthens and repairs damaged hair from root to tip, helping to stop split ends and breakage in their tracks, while giving your hair a natural, healthy shine without weighing it down. Made in Switzerland with a luxurious blend of five nourishing oils — including amaranth, argan, abyssinian, cuckoo flower, and babassu oils — this vegan, silicone-free serum deeply regenerates and protects hair structure. The high-quality pump applicator makes it easy to use just the right amount: a little goes a long way. One or two pumps on damp or dry hair smooth frizz and leave your locks silky, soft, and radiant all day long, with a subtle, fresh scent of apricot and floral notes. Pair it with the Rausch Damaged Hair Repair Shampoo for better results.
