Hair serum that provides good nourishment

The Repair Shine Oil Serum is the Amos product I use the most. Oils tend to feel a bit heavy, so I usually apply them to wet hair and then dry it with a hairdryer. However, this product isn't too oily even when applied to dry hair, which is great. It is also excellent for managing damaged hair when applied to the ends, so I find myself continuing to use it.
