This hand crafted hair oil was created using fresh rosemary oil (also handcrafted by the seller), jojoba oil, grape seed oil, sweet almond oil, organic calendula and chamomile extract, vitamin E, and pure peppermint essential oil. This mixture has been proven to strengthen and even lengthen hair. Rosemary oil has many benefits for hair including, promoting hair growth, reducing dandruff, preventing premature graying (*this is why I made it and it works wonders! My gray hairs are very limited now!), and it may help treat alopecia areata or patchy hair loss. This is a handcrafted product and although it helps my hair it may not work for everyone. As always be aware of any allergies you may have, every ingredient used is listed.
