Rapunzel Hair Growth Oil strives to give you the hair you've always wanted. Rosemary, combined with other nourishing herbs, stimulates hair follicles to promote growth, lengthen strands, and nourish for less breakage. Coconut, olive, rosemary, peppermint, lavender, nettle, and ginger oils combine in this treatment. Simply section hair, apply to the scalp, and massage for one to two minutes.
