So you’ve probably heard the buzz about Castor - healthy, strong hair plus boost new growth? Check! It is GREAT, but if you haven’t tried it yet, we’re going to let you in on a little secret: it’s thick and sticky with a natural smell that, well, leaves something to be desired. Our solution? Combine Castor Oil with other hair-loving botanicals. Meet Rosemary & Castor Hair Oil! Packed full of Castor’s happy hair benefits - but better! We’ve blended Castor with Sweet Almond Oil to give this formula a silky soft feel and some added benefits (smooth, shiny strands!), and the scent? You’ll love the fresh, herbal notes that Rosemary Essential Oil provides, plus it supports hair growth and a healthy scalp. What could be better? Three clean, simple ingredients for gorgeous hair you’ll love! You can thank us later!

Prunus Amygdalus Dulcis (Sweet Almond) Oil, Ricinus Communis (Castor) Seed Oil, Rosmarinus Officinalis (Rosemary) Leaf/Stem Oil.

Pre-Wash: Fill the dropper with oil and apply directly to your hairline. Gently massage into scalp. Apply more or less as needed. Leave in for 30 minutes (or overnight if desired) and wash out with shampoo. Leave-In: Add a few drops of oil to your fingertips and rub together. Apply oil evenly through clean strands, focusing on the ends.

A little goes a long way, so use sparingly to achieve desired look.
