If I had to pick my favourite thing about the Amika The Kure Multi-task Repair Treatment ($28), it'd be how light it is. The product has a light jelly texture that's so easy to apply without overdoing it thanks to the bottle's nozzle applicator. This treatment is meant to be used to reduce breakage and strengthen the hair, but it can also be used as a leave-in depending on how damaged your hair might be.
